CHRONOLOGY (from the Greek χρονολογία, computation of time) is the science which treats of time. Its object is to arrange and exhibit the various events which have occurred in the history of the world in the order of their succession, and to ascertain the intervals of time between them.

The preservation of any record, however rude, of the lapse of time implies some knowledge of the celestial motions, by which alone time can be accurately measured, and some advancement in the arts of civilized life, which could only be attained by the accumulated experience of many generations. Before the invention of letters the memory of past transactions could not be preserved beyond a few years with any tolerable degree of accuracy. Events which greatly affected the physical condition of the human race, or were of a nature to make a deep impression on the minds of the rude inhabitants of the earth, might be vaguely transmitted through several ages by traditional narrative; but intervals of time, expressed by abstract numbers, and these constantly varying besides, would soon escape the memory. The invention of the art of writing afforded the means of substituting precise and permanent records for vague and evanescent tradition; but in the infancy of the world, mankind had learned neither to estimate accurately the duration of time, nor to refer passing events to any fixed epoch. Writing was practised many centuries before historians began to assign dates to the events they narrated. The masterpieces of Herodotus and Thucydides, while setting forth, each in the manner suited to the author's aim, events in the order of their succession, are stories without dates.

For these reasons the history of the early ages of the world is involved in almost impenetrable obscurity, and chronology, comparatively speaking, is only of recent origin. After political relations began to be established, the necessity of preserving a register of passing seasons and years would soon be felt, and the practice of recording important transactions must have grown up as a necessary consequence of social life. But of these early records a very small portion only has escaped the ravages of time and barbarism.

The earliest written annals of the Greeks, Etruscans, and Romans are irretrievably lost. The traditions of the Druids perished with them. A Chinese emperor has the credit of burning “the books” extant in his day (about 220 B.C.), and of burying alive the scholars who were acquainted with them. And a Spanish adventurer destroyed the picture records which were found in the pueblo of Montezuma.
Of the more formal historical writings in which the first ineffectual attempts were made in the direction of systematic chronology we have no knowledge at first-hand. Of Hellenicus, the Greek logographer, who appears to have lived through the greater part of the 5th century B.C., and who drew up a chronological list of the priestesses of Hera at Argos; of Ephorus, who lived in the 4th century B.C., and is distinguished as the first Greek who attempted the composition of a universal history; and of Timæus, who in the following century wrote an elaborate history of Sicily, in which he set the example of using the Olympiads as the basis of chronology, the works have perished, and our meagre knowledge of their contents is derived only from fragmentary citations in later writers. The same fate has befallen the works of Berosus and Manetho, Eratosthenes and Apollodorus. Berosus, a priest of Belus living at Babylon in the 3d century B.C., added to his historical account of Babylonia a chronological list of its kings, which he claimed to have compiled from genuine archives preserved in the temple. Manetho, likewise a priest, living at Sebennytus in Lower Egypt in the 3d century B.C., wrote in Greek a history of Egypt, with an account of its thirty dynasties of sovereigns, which he professed to have drawn from genuine archives in the keeping of the priests. Of these works fragments only, more or less copious and accurate, have been preserved. Eratosthenes, who in the latter half of the 2d century B.C. was keeper of the famous Alexandrian Library, not only made himself a great name by his important work on geography, but by his treatise entitled Chronographia, one of the first attempts to establish an exact scheme of general chronology, earned for himself the title of “father of chronology.” His method of procedure, however, was usually conjectural; and guess-work, however careful, acute, and plausible, is still guess-work and not testimony. Apollodorus, an Athenian who flourished in the middle of the 2d century B.C., wrote a metrical chronicle of events, ranging from the supposed period of the fall of Troy to his own day. These writers were followed by other investigators and systematizers in the same field, but their works are lost. Of the principal later writers whose works are extant, and to whom we owe what little knowledge we possess of the labours of their predecessors, mention will be made hereafter.
The absence or incompleteness of authentic records, however, is not the only source of obscurity and confusion in the chronology of remote ages. There can be no exact computation of time or placing of events without a fixed point or epoch from which the reckoning takes its start. It was long before this was apprehended. When it began to be seen, various epochs were selected by various writers; and at first each small separate community had its own epoch and method of time-reckoning. Thus in one city the reckoning was by succession of kings, in another by archons or annual magistrates, in a third by succession of priests. It seems now surprising that vague counting by generations should so long have prevailed and satisfied the wants of inquiring men, and that so simple, precise, and seemingly obvious a plan as counting by years, the largest natural division of time, did not occur to any investigator before Eratosthenes.
Precision, which was at first unattainable for want of an epoch, was afterwards no less unattainable from the multiplicity, and sometimes the variation, of epochs. But by a natural process the mischief was gradually and partially remedied. The extension of intercourse between the various small groups or societies of men, and still more their union in larger groups, made a common epoch necessary, and led to the adoption of such a starting point by each larger group. These leading epochs continued in use for many centuries. The task of the chronologer was thus simplified and reduced to a study and comparison of dates in a few leading systems.
The most important of these systems In what we call ancient times were the Babylonian, the Greek, and the Roman. The Jews had no general era, properly so called. In the history of Babylonia, the fixed point from which time was reckoned was the era of Nabonassar, 747 B.C. Among the Greeks the reckoning was by Olympiads, the point of departure being the year in which Corœbus was victor in the Olympic Games, 776 B.C. The Roman chronology started from the foundation of the city, the year of which, however, was variously given by different authors. The most generally adopted was that assigned by Varro, 753 B.C. It is noteworthy how nearly these three great epochs approach each other,—all lying near the middle of the 8th century B.C. But it is to be remembered that the beginning of an era and its adoption and use as such are not the same thing, nor are they necessarily synchronous, Of the three ancient eras above spoken of, the earliest is that of the Olympiads, next that of the foundation of Rome, and the latest the era of Nabonassar. But in order of adoption and actual usage the last is first. It is believed to have been in use from the year of its origin. It is not known when the Romans began to use their era. The Olympiads were not in current use till about the middle of the 3d century B.C., when Timæus, as already mentioned, set the example of reckoning by them. Of these and other ancient and modern eras a full account is given in the following pages.
Even after the adoption in Europe of the Christian era, a great variety of methods of dating—national, provincial, and ecclesiastical—grew up and prevailed for a long time in different countries, thus renewing in modern times the difficulties experienced in ancient times from diversities of reckoning. An acquaintance with these various methods is indispensable to the student of the charters, chronicles, and legal instruments of the Middle Ages.
In reckoning years from any fixed epoch in constant succession, the number denoting the years is necessarily always on the increase. But rude nations and illiterate people seldom attach any definite idea to large numbers. Hence it has been a practice, very extensively followed, to employ cycles or periods, consisting of a moderate number of years, and to distinguish and reckon the years by their number in the cycle. The Chinese and other nations of Asia reckon, not only the years, but also the months and days, by cycles of sixty. The Saros of the Chaldeans, the Olympiad of the Greeks, and the Roman Indiction are instances of this mode of reckoning time. Several cycles were formerly known in Europe; but most of them were invented for the purpose of adjusting the solar and lunar divisions of time, and were rather employed in the regulation of the calendar than as chronological eras. They are frequently, however, of very great use in fixing dates that have been otherwise imperfectly expressed, and consequently form important elements of chronology.
Chronology has shared with history the fruits of the novel researches and remarkable discoveries in the field of antiquity which have especially distinguished the present century. The memorabilia of early peoples and ages were set down not only in written records but in monumental inscriptions. The latter, graven on stone or metal, could resist the touch of time and the hand of the barbarian better than the former; and although at various times terrible havoc has been made among them, immense numbers are in existence to this day. In Assyria, Egypt, Persia, Greece, and Italy, the practice of monumental inscription was very general. These inscriptions have attracted the attention of learned men from very remote ages. But as contributions to history and chronology, they have within the present century risen into new and surprising importance. By Grotefend's decipherment of the cuneiform characters, the language of the Babylonian and Persian inscriptions, and by Young's decipherment of hieroglyphics, the language of the Egyptian monuments, two discoveries made within a few years of each other, new fields of vast extent and unknown richness have been opened to historical explorers. These fields are now being diligently worked by some of the greatest living scholars; and from granite block and fragile papyrus roll results are already obtained of rare value and of rarer promise. The Assyrian inscribed cylinders, disinterred but thirty years ago, are yielding up the secrets of a long-buried past, enlarging the horizon of history, and even furnishing the means of giving a precise chronology to periods where all was vague. The publication of the Assyrian Canon by Sir Henry Rawlinson in 1862, verified as it was by the subsequent discovery of a record of a solar eclipse, must mark an epoch in chronological science. Egyptian researches and interpretations have been of similar service, and have strongly tended, if not to establish the complete accuracy, at least to indicate the credibility, of Manetho's account of the Egyptian dynasties. The period through which these dynasties apparently reached was so vast, stretching so far beyond the traditionally accepted limits of man's existence on the earth, that modern chronologers, when they grew critical, could for a long time only shake their heads in profound doubt over Manetho and his vistas of shadowy kings. For Egyptian chronology the discovery by Mariette, in 1864, of the Apis Stelæ is one of the highest importance. A flood of light has been poured on some obscure pages of early Persian history by the great cuneiform inscription of Behistun, discovered in 1835 by Colonel Rawlinson, who subsequently copied and translated it.
In the article Calendar (q.v.), that part of chronology has been already treated of which relates to the measurement of time, and the principal methods explained with sufficient detail that have been employed, or are still in use, for adjusting the lunar months of the solar year, as well as the intercalations necessary for regulating the civil year according to the celestial motions. In the present article it is our purpose to give an account (without repeating what has been discussed in full in the article just named) of the different Eras and Periods that have been employed by historians, and by the different nations of the world, in recording the succession of time and events, to fix the epochs at which the eras respectively commenced, to ascertain the form and the initial day of the year made use of, and to establish their correspondence with the years of the Christian era. These elements will enable us to convert, by a simple arithmetical operation, any historical date, of which the chronological characters are given according to any era whatever, into the corresponding date in our common are of the Incarnation.

Julian Period.

Although the Julian Period (the invention of Joseph Scaliger, in 1582) is not, properly speaking, a chronological era, yet, on account of its affording considerable facilities in the comparison of different eras with one another, and in marking without ambiguity the years before Christ, it is very generally employed by chronologers. It consists of 7980 Julian years; and the first year of the Christian era corresponded with the year 4714 of the Julian period. (See vol. iv. p. 670.)


The Olympic games, so famous in Greek history, were celebrated once every four years, between the new and full moon first following the summer solstice, on the small plain named Olympia in Elis, which was bounded on one side by the River Alpheus, on another by the small tributary stream the Cladeus, and on the other two sides by mountains. The games lasted five days. Their origin, lost in the dimness of remote antiquity, was invested by priestly legends with a sacred character. They were said to have been instituted by the Idæan Heracles, to commemorate his victory over his four brothers in a foot race. According to a tradition, possibly more authentic, they were re-established by Iphitus, king of Elis, in concert with the Spartan Lycurgus and Cleosthenes of Pisa. The practice was long afterwards adopted of designating the Olympiad, or period of four years, by the name of the victor in the contests of the stadium, and of inscribing his name in the gymnasium of Olympia. The first who received this honour was Corœbus. The games in which Corœbus was victor, and which form the principal epoch of Greek history, were celebrated about the time of the summer solstice 776 years before the common era of the Incarnation, in the 3938th year of the Julian period, and twenty-three years, according to the account of Varro, before the foundation of Rome. Before the introduction of the Metonic cycle, the Olympic year began sometimes with the full moon which followed, at other times with that which preceded the summer solstice, because the year sometimes contained 384 days instead of 354. But subsequently to its adoption, the year always commenced with the eleventh day of the moon which followed the solstice. In order to avoid troublesome computations, which it would be necessary to recommence for every year, and of which the results differ only by a few days, chronologers generally regard the 1st of July as the commencement of the Olympic year. Some authors, however, among whom are Eusebius, Jerome, and the historian Socrates, place its commencement at the 1st of September; these, however, appear to have confounded the Olympic year with the civil year of the Greeks, or the era of the Seleucidæ.
It is material to observe, that as the Olympic years and periods begin with the 1st of July, the first six months of a year of our era correspond to one Olympic year, and the last six months to another. Thus, when it is said that the first year of the Incarnation corresponds to the first of the 195th Olympiad, we are to understand that it is only with respect to the last six months of that year that the correspondence takes place. The first six months belonged to the fourth year of the 194th Olympiad. In referring dates expressed by Olympiads to our era, or the contrary, we must therefore distinguish two cases.
1st, When the event in question happened between the 1st of January and the 1st of the following July, the sum of the Olympic year and of the year before Christ is always equal to 776. The year of the era, therefore, will be found by subtracting the number of the Olympic year from 776. For example, Varro refers the foundation of Rome to the 21st of April of the third year of the sixth Olympiad, and it is required to find the year before our era. Since five Olympic periods have elapsed, the third year of the sixth Olympiad is 5 × 4 + 3 = 23; therefore, subtracting 23 from 776, we have 753, which is the year before Christ to which the foundation of Rome is referred by Varro.
2d, When the event took place between the summer solstice and the 1st of January following, the sum of the Olympic year and of the year before Christ is equal to 777. The difference therefore between 777 and the year in one of the dates will give the year in the other date. Thus, the moon was eclipsed on the 27th of August, a little before midnight, in the year 413 before our era; and it is required to find the corresponding year in the Olympic era. Subtract 413 from 777, the remainder is 364; and 364 divided by four gives 91 without a remainder; consequently the eclipse happened in the fourth year of the ninety-first Olympiad, which is the date to which it is referred by Thucydides.
If the year is after Christ, and the event took place in one of the first six months of the Olympic year, that is to say, between July and January, we must subtract 776 from the number of the Olympic year to find the corresponding year of our era; but if it took place in one of the last six months of the Olympic year, or between January and July, we must deduct 777. The computation by Olympiads seldom occurs in historical records after the middle of the 5th century of our era.
The names of the months were different in the different Grecian states. The Attic months, of which we possess the most certain knowledge, were named as follows:—

Hecatombæon.  Gamelion.
Metageitnion. Anthesterion.
Boedromion. Elaphebolion.
Pyanepsion. Munychion.
Mæmacterion. Thargelion.
Poseideon. Scirophorion.

Era of the Foundation of Rome.

After the Olympiads, the era most frequently met with in ancient history is that of the foundation of Rome, which is the chronological epoch adopted by all the Roman historians. There are various opinions respecting the year of the foundation of Rome.
1st, Fabius Pictor places this event in the latter half of the first year of the eighth Olympiad, which corresponds with the 3967th of the Julian period, and with the year 747 B.C.
2d, Polybius places it in the second year of the seventh Olympiad, corresponding with 3964 of the Julian period, and 750 B.C.
3d, M. Porcius Cato places it in the first year of the seventh Olympiad, that is, in 3963 of the Julian period, and 751 B.C.
4th, Verrius Flaccus places it in the fourth year of the sixth Olympiad, that is, in the year 3962 of the Julian period, and 752 B.C.
5th, Terentius Varro places it in the third year of the sixth Olympiad, that is, in the year 3961 of the Julian period, and 753 B.C.
A knowledge of these different computations is necessary, in order to reconcile the Roman historians with one another, and even any one writer with himself. Livy in general adheres to the epoch of Cato, though he sometimes follows that of Fabius Pictor. Cicero follows the account of Varro, which is also in general adopted by Pliny. Dionysius of Halicarnassus follows Cato. Modern chronologers for the most part adopt the account of Varro, which is supported by a passage in Censorinus, where it is stated that the 991st year of Rome commenced with the festival of the Palilia, in the consulship of Ulpius and Pontianus. Now this consulship corresponded with the 238th year of our era; therefore, deducting 238 from 991, we have 753 to denote the year before Christ. The Palilia commenced on the 21st of April; and all the accounts agree in regarding that day as the epoch of the foundation of Rome.
The Romans employed two sorts of years, the civil year, which was used in the transaction of public and private affairs, and the consular year, according to which the annals of their history have been composed. The civil year commenced with the calends of January, but this did not hold a fixed place in the solar year till the time of Julius Cæsar (see vol. iv. p. 666.) The installation of the consuls regulated the commencement of the consular year. The initial day of the consulate was never fixed, at least before the 7th century of Rome, but varied with the different accidents which in times of political commotion so frequently occurred to accelerate or retard the elections. Hence it happens that a consular year, generally speaking, comprehends a part not only of two Julian years, but also of two civil years. The consulate is the date employed by the Latin historians generally, and by many of the Greeks, down to the 6th century of our era.
In the era of Rome the commencement of the year is placed at the 21st of April; an event therefore which happened in the months of January, February, March, or during the first twenty days of April, in the year (for example) 500 of Rome, belongs to the civil year 501. Before the time of the Decemvirs, however, February was the last month of the year. Many authors confound the year of Rome with the civil year, supposing them both to begin on the 1st of January. Others again confound both the year of Rome and the civil year with the Julian year, which in fact became the civil year after the regulation of the calendar by Julius Cæsar. Through a like want of attention, many writers also, particularly among the moderns, have confounded the Julian and Olympic years, by making an entire Julian year correspond to an entire Olympic year, as if both had commenced at the same epoch. Much attention to these particulars is required in the comparison of ancient dates.

The Christian Era.

The Christian or vulgar era, called also the era of the Incarnation, is now almost universally employed in Christian countries, and is even used by some Eastern nations. Its epoch or commencement is the 1st of January in the fourth year of the 194th Olympiad, the 753d from the foundation of Rome, and the 4714th of the Julian period. It is usually supposed to begin with the year of the birth of Christ, but there are various opinions with regard to the year in which that event took place. This epoch was introduced in Italy in the 6th century, by Dionysius the Little, a Roman abbot, and began to be used in Gaul in the 8th, though it was not generally followed in that country till a century later. From extant charters it is known to have been in use in England before the close of the 8th century. Before its adoption the usual practice in Latin countries was to distinguish the years by their number in the cycle of Indiction.
In the Christian era the years are simply distinguished by the cardinal numbers; those before Christ being marked B.C. (Before Christ), or a.c. (Ante Christum), and those after Christ A.D. (Anno Domini). This method of reckoning time is more convenient than those which employ cycles or periods of any length whatever; but it still fails to satisfy in the simplest manner possible all the conditions that are necessary for registering the succession of events. For, since the commencement of the era is placed at an intermediate period of history, we are compelled to resort to a double manner of reckoning, backward as well as forward. Some ambiguity is also occasioned by the want of uniformity in the method of numbering the preceding years. Astronomers denote the year which preceded the first of our era by 0, and the year previous to that by 1 B.C.; but chronologers, in conformity with common notions, call the year preceding the era 1 B.C., the previous year 2 B.C., and so on. By reckoning in this manner, there is an interruption in the regular succession of the numbers; and in the years preceding the era, the leap years, instead of falling on the fourth, eighth, twelfth, &c., fall, or ought to fall, on the first, fifth, ninth, &c.
In the chronicles of the Middle Ages much uncertainty frequently arises respecting dates on account of the different epochs assumed for the commencement of the Christian year. Dionysius, the author of the era, adopted the day of the Annunciation, or the 25th of March, which preceded the birth of Christ by nine months, as the commencement of the first year of the era. This epoch therefore precedes that of the vulgar era by nine months and seven days. This manner of dating was followed in some of the Italian states, and continued to be used at Pisa even down to the year 1745. It was also adopted in some of the Papal bulls; and there are proofs of its having been employed in France about the middle of the 11th century. Some chroniclers, who adhere to the day of the Annunciation as the commencement of the year, reckon from the 25th of March following our epoch, as the Florentines in the 10th century. Gregory of Tours, and some writers of the 6th and 7th centuries, make the year commence some times with the 1st of March, and sometimes with the 1st of January. In France, under the third race of kings, it was usual to begin the year with Easter; and this practice continued at least till the middle of the 16th century, for an edict was issued by Charles IX. in the month of January 1663, ordaining that the commencement of the year should thenceforth be considered as taking place on the 1st of January. An instance is given, in L'Art de Vérifier les Dates, of a date in which the year is reckoned from the 18th of March; but it is probable that this refers to the astronomical year, and that the 18th of March was taken for the day of the vernal equinox. In Germany, about the 11th century, it was usual to commence the year at Christmas; and this practice also prevailed at Milan, Rome, and other Italian cities, in the 13th, 14th, and 15th centuries.
In England, the practice of placing the beginning of the year at Christmas was introduced in the 7th century, and traces of it are found even in the 13th. Gervase of Canterbury, who lived in the 13th century, mentions that almost all writers of his country agreed in regarding Christmas day as the first of the year, because it forms, as it were, the term at which the sun finishes and recommences his annual course. In the 12th century, however, the custom of beginning the civil year with the day of the Annunciation, or the 25th of March, began to prevail, and continued to be generally followed from that time till the reformation of the calendar in 1752. The historical year has always been reckoned by English authors to begin with the 1st of January. The liturgic year of the Church of England commences with the first Sunday of Advent.
A knowledge of the different epochs which have been chosen for the commencement of the year in different countries is indispensably necessary to the right interpretation of ancient chronicles, charters, and other documents in which the dates often appear contradictory. We may cite an example or two. It is well known that Charles the Great was crowned emperor at Rome on Christmas day in the year 800, and that he died in the year 814, according to our present manner of reckoning. But in the annals of Metz and Moissac, the coronation is stated to have taken place in the year 801, and his death in 813. In the first case the annalist supposes the year to begin with Christmas, and accordingly reckons the 25th of December and all the following days of that month to belong to 801, whereas in the common reckoning they would be referred to the year 800. In the second case the year has been supposed to begin with the 25th of March, or perhaps with Easter; consequently the first three months of the year 814, reckoning from the 1st of January, would be referred to the end of the year 813. The English Revolution is popularly called the Revolution of 1688. Had the year then begun, as it now does, with the 1st of January, it would have been the revolution of 1689, William and Mary being received as king and queen in February in the year 1689; but at that time the year was considered in England as beginning on the 25th of March. Another circumstance to which it is often necessary to pay attention in the comparison of dates, is the alteration of style which took place on the adoption of the Gregorian Calendar (see vol. iv. pp. 671 sqq.)

Era of the Creation of the World.

As the Greek and Roman methods of computing time were connected with certain pagan rites and observances, which the Christians held in abhorrence, the latter began at an early period to imitate the Jews in reckoning their years from the supposed period of the creation of the world. The chronological elements on which both Jews and Christians founded their computations for determining this period were derived from the Old Testament narratives, which have been transmitted to us through three distinct channels. These are the Hebrew text of the Scriptures, the Samaritan text, and the Greek version known as the Septuagint. In respect of chronology, the three accounts are totally irreconcilable with each other; and no conclusive reason can be given for preferring any one of them to another. We have no concurrent testimony with which to compare them; nor is it even known which of them was regarded as the most probable by the Jews themselves, when the books of the Old Testament were revised and transcribed by Ezra. The ordinary rules of probability cannot be applied to a state of things in which the duration of human life is represented as extending to nearly a thousand years.
From computations founded on loose and conflicting data it would be vain to look for knowledge or even for concord of opinion. From the very nature of the case discussion is hopeless labour. The subject is one to which the saying Quot homines tot sententiæ applies with almost literal truth. Des Vignoles, in the preface to his Chronology of Sacred History, asserts that he collected upwards of two hundred different calculations, the shortest of which reckons only 3483 years between the creation of the world and the commencement of the vulgar era, and the longest 6984. The difference amounts to thirty-five centuries. It suffices, therefore, to point out that the so-called era of the creation of the world is a purely conventional and arbitrary epoch; that, practically, it means the year 4004 B.C., this being the date which, under the sanction of Archbishop Ussher's opinion, has won its way, among its hundreds of competitors, into most general acceptance. The reader who is desirous of more detailed information on this subject may consult the first volume of the Universal History, or L'Art de Vérifier les Dates, avant J. C., p. 9.

Jewish Year and Eras.

Before the departure of the Israelites from Egypt their year commenced at the autumnal equinox; but in order to solemnize the memory of their deliverance, the month of Nisan or Abib, in which that event took place, and which falls about the time of the vernal equinox, was afterwards regarded as the beginning of the ecclesiastical or legal year. In civil affairs, and in the regulation of the jubilees and sabbatical years, the Jews still adhere to the ancient year, which begins with the month Tisri, about the time of the autumnal equinox. (On the regulation of the Jewish year, see vol. iv. p. 677.)
After their dispersion, the Jews were constrained to have recourse to the astronomical rules and cycles of the more enlightened heathen, in order that their religious festivals might be observed on the same days in all the countries through which they were scattered. For this purpose they adopted a cycle of eighty-four years, which is mentioned by several of the ancient fathers of the church, and which the early Christians borrowed from them for the regulation of Easter. This cycle seems to be neither more nor less than the Calippic period of seventy-six years, with the addition of a Greek octæteris, in order to disguise its true source, and give it an appearance of originality. In fact, the period of Calippus containing 27,759 days, and the octæteris 2922 days (see vol. iv. p. 688), the sum, which is 30,681, is exactly the number of days in eighty-four Julian years. But the addition was very far from being an improvement on the work of Calippus; for instead of a difference of only five hours and fifty-three minutes between the places of the sun and moon, which was the whole error of the Calippic period, this difference, in the period of eighty-four years, amounted to one day, six hours, and forty-one minutes. Buccherius places the commencement of this cycle in the year 162 B.C.; Prideaux in the year 291 B.C. According to the account of Prideaux, the fifth cycle must have commenced in the year 46 of our era; and it was in this year, according to St Prosperus, that the Christians began to employ the Jewish cycle of eighty-four years, which they followed, though not uniformly, for the regulation of Easter, till the time of the Council of Nice.
Soon after the Nicene council, the Jews, in imitation of the Christians, abandoned the cycle of eighty-four years, and adopted that of Meton, by which their lunisolar year is regulated at the present day. This improvement was first proposed by Rabbi Samuel, rector of the Jewish school of Sora in Mesopotamia, and was finally accomplished in the year 360 of our era by Rabbi Hillel, who introduced that form of the year which the Jews at present follow, and which, they say, is to endure till the coming of the Messiah.
Till the 15th century the Jews usually followed the era of the Seleucidæ or of Contracts. Since that time they have generally employed a mundane era, and dated from the creation of the world, which, according to their computation, took place 3760 years and about three months before the commencement of our era. No rule can be given for determining with certainty the day on which any given Jewish year begins, without entering into the minutiæ of their irregular and complicated calendar. A table comprising twelve cycles of Jewish years will be found at pp. 678, 679 of vol. iv.

Era of Constantinople.

This era, which is still used in the Greek Church, and was followed by the Russians till the time of Peter the Great, dates from the creation of the world. The Incarnation falls in the year 5509, and corresponds, as in our era, with the fourth year of the 194th Olympiad. The civil year commences with the 1st of September; the ecclesiastical year sometimes with the 21st of March, sometimes with the 1st of April. It is not certain whether the year was considered at Constantinople as beginning with September before the separation of the Eastern and Western empires.
At the commencement of our era there had elapsed 5508 years and four months of the era of Constantinople. Hence the first eight months of the Christian year 1 coincide with the Constantinopolitan year 5509, while the last four months belong to the year 5510. In order, therefore, to find the year of Christ corresponding to any given year in the era of Constantinople, we have the following rule:—If the event took place between the 1st of January and the end of August, subtract 5508 from the given year; but if it happened between the 1st of September and the end of the year, subtract 5509.

Era of Alexandria.

The chronological computation of Julius Africanus was adopted by the Christians of Alexandria, who accordingly reckoned 5500 years from the creation of Adam to the birth of Christ. But in reducing Alexandrian dates to the common era, it must be observed that Julius Africanus placed the epoch of the Incarnation three years earlier than it is placed in the usual reckoning, so that the initial day of the Christian era fell in the year 5503 of the Alexandrian era. This correspondence, however, continued only from the introduction of the era till the accession of Diocletian, when an alteration was made by dropping ten years in the Alexandrian account. Diocletian ascended the imperial throne in the year of Christ 284. According to the Alexandrian computation, this was the year 5787 of the world, and 287 of the Incarnation; but on this occasion ten years were omitted, and that year was thence forth called the year 5777 of the world, and 277 of the Incarnation. There are, consequently, two distinct eras of Alexandria, the one being used before and the other after the accession of Diocletian. It is not known for what reason the alteration was made; but it is conjectured that it was for the purpose of causing a new revolution of the cycle of nineteen years (which was introduced into the ecclesiastical computation about this time by Anatolius, bishop of Hierapolis) to commence with the first year of the reign of Diocletian. In fact, 5777 being divided by 19 leaves 1 for the year of the cycle. The Alexandrian era continued to be followed by the Copts in the 15th century, and is said to be still used in Abyssinia.
Dates expressed according to this era are reduced to the common era by subtracting 5502, up to the Alexandrian year 5786 inclusive, and after that year by subtracting 5492; but if the date belongs to one of the four last months of the Christian year, we must subtract 5503 till the year 5786, and 5493 after that year.

Mundane Era of Antioch.

The chronological reckoning of Julius Africanus formed also the basis of the era of Antioch, which was adopted by the Christians of Syria, at the instance of Panodorus, an Egyptian monk, who flourished about the beginning of the 4th century. Panodorus struck off ten years from the account of Julius Africanus with regard to the years of the world, and he placed the Incarnation three years later, referring it to the fourth year of the 194th Olympiad, as in the common era. Hence the era of Antioch differed from the original era of Alexandria by ten years; but after the alteration of the latter at the accession of Diocletian, the two eras coincided. In reckoning from the Incarnation, however, there is a difference of seven years, that epoch being placed, in the reformed era of Alexandria, seven years later than in the mundane era of Antioch or in the Christian era.
As the Syrian year began in autumn, the year of Christ corresponding to any year in the mundane era of Antioch is found by subtracting 5492 or 5493 according as the event falls between January and September or from September to January.

Era of Nabonassar


This era is famous in astronomy, having been generally followed by Hipparchus and Ptolemy. It is believed to have been in use from the very time of its origin; for the observations of eclipses which were collected in Chaldea by Callisthenes, the general of Alexander, and transmitted by him to Aristotle, were for the greater part referred to the commencement of the reign of Nabonassar, founder of the kingdom of the Babylonians. It is the basis of the famous Canon of Kings, also called Mathematical Canon, preserved to us in the works of Ptolemy, which, before the recent astonishing discoveries at Nineveh, was the sole authentic monument of Assyrian and Babylonian history known to us. The epoch from which it is reckoned is precisely determined by numerous celestial phenomena recorded by Ptolemy, and corresponds to Wednesday at mid-day, the 26th of February of the year 747 before Christ. The year was in all respects the same as the ancient Egyptian year. On account of the difference in the length of the Julian and Babylonian years, the conversion of dates according to the era of Nabonassar into years before Christ is attended with considerable trouble. The surest way is to follow a comparative table. Frequently the year cannot be fixed with certainty, unless we know also the month and the day.
The Greeks of Alexandria formerly employed the era of Nabonassar, with a year of 365 days; but soon after the reformation of the calendar by Julius Cæsar, they adopted, like other Roman provincials, the Julian intercalation. At this time the first of Thoth had receded to the 29th of August. In the year 136 of our era, the first of Thoth in the ancient Egyptian year corresponded with the 20th of July, between which and the 29th of August there are forty days. The adoption of the Julian year must therefore have taken place about 160 years before the year 136 of our era (the difference between the Egyptian and Julian years being one day in four years), that is to say, about the year 25 B.C. In fact, the first of Thoth corresponded with the 29th of August in the Julian calendar, in the years 25, 24, 23, and 22 B.C.

Era of the Seleucidæ, or Macedonian Era.

The era of the Seleucidæ dates from the time of the occupation of Babylon by Seleucus Nicator, 311 years before Christ, in the year of Rome 442, and twelve years after the death of Alexander the Great. It was adopted not only in the monarchy of the Seleucidæ but in general in all the Greek countries bordering on the Levant, was followed by the Jews till the 15th century, and is said to be used by some Arabians even at the present day. By the Jews it was called the Era of Contracts, because the Syrian governors compelled them to make use of it in civil contracts; the writers of the books of Maccabees call it the Era of Kings. But notwithstanding its general prevalence in the East for many centuries, authors using it differ much with regard to their manner of expressing dates, in consequence of the different epochs adopted for the commencement of the year. Among the Syrian Greeks the year began with the mouth Elul, which corresponds to our September. The Nestorians and Jacobites at the present day suppose it to begin with the following month, or October. The author of the first book of Maccabees makes the era commence with the month Nisan, or April; and the author of the second book with the first Tishrin, or October. Albategni, a celebrated Arabian astronomer, dates from the 1st of October. Some of the Arabian writers, as Alfergani, date from the 1st of September. At Tyre the year was counted from the 19th of our October, at Gaza from the 28th of the same month, and at Damascus from the vernal equinox. These discrepancies render it extremely difficult to determine the exact correspondence of Macedonian dates with those of other eras; and the difficulty is rendered still greater by the want of uniformity in respect of the length of the year. Some authors who follow the Macedonian era, use the Egyptian or vague year of 365 days; Albategni adopts the Julian year of 3651/4 days.
According to the computation most generally followed, the year 312 of the era of the Seleucidæ began on the 1st of September in the Julian year preceding the first of our era. Hence, to reduce a Macedonian date to the common era, subtract 311 years and four months.
The names of the Syrian and Macedonian months, and their correspondence with the Roman months, are as follows:—

Syrian. Macedonian. English.
Elul. Gorpiæus. September.
Tishrin I. Hyperberetæus. October.
Tishrin II. Dius. November.
Canun I. Apellæus. December.
Canun II. Audynæus. January.
Sabat. Peritius. February.
Adar. Dystrus. March.
Nisan. Xanthicus. April.
Ayar. Artemisius. May.
Haziran. Dæsius. June.
Tamus. Panemus. July.
Ab. Loüs. August.

Era of Alexander.

Some of the Greek historians have assumed as a chronological epoch the death of Alexander the Great, which took place in the year 325 B.C. The form of the year is the same as in the preceding era. This era has not been much followed; but it requires to be noticed in order that it may not be confounded with the era of the Seleucidæ.

Era of Tyre.

The era of Tyre is reckoned from the 19th of October, or the beginning of the Macedonian month Hyperberetæus, in the year 126 B.C. In order, therefore, to reduce it to the common era, subtract 125; and when the date is B.C., subtract it from 126. Dates expressed according to this era occur only on a few medals, and in the acts of certain councils.

Cæsarean Era of Antioch.

This era was established to commemorate the victory obtained by Julius Cæsar on the plains of Pharsalia, on the 9th of August in the year 48 B.C., and the 706th of Rome. The Syrians computed it from their month Tishrin I.; but the Greeks threw it back to the month Gorpiæus of the preceding year. Hence there is a difference of eleven months between the epochs assumed by the Syrians and the Greeks. According to the computation of the Greeks, the year of the Cæsarean era began in the autumn of the year preceding the commencement of the Christian era; and, according to the Syrians, the 49th year began in the autumn of the first year of the Incarnation. It is followed by Evagrius in his Ecclesiastical History.

Julian Era.

The Julian era commences with the 1st of January, forty-five years B.C. It was designed to commemorate the reformation of the Roman calendar by Julius Cæsar.

Era of Spain, or of the Cæsars.

The conquest of Spain by Augustus, which was completed in the thirty-ninth year B.C., gave rise to this era, which began with the first day of the following year, and was long used in Spain and Portugal, and generally in all the Roman provinces subdued by the Visigoths, both in Africa and the South of France. Several of the councils of Carthage, and also that of Aries, are dated according to this era. After the 9th century it became usual to join with it in public acts the year of the Incarnation. It was followed in Catalonia till the year 1180, in the kingdom of Aragon till 1350, in Valencia till 1358, and in Castile till 1382. In Portugal it is said to have been in use so late as the year 1415, or 1422, though it would seem that after the establishment of the Portuguese monarchy, no other era was used in the public acts of that country than that of the Incarnation. As the era of Spain commenced with the 1st of January, and the months and days of the year are those of the Julian calendar, any date is reduced to the common era by subtracting thirty-eight from the number of the year.

Era of Actium, and Era of Augustus.

This era was established to commemorate the battle of Actium, which was fought on the 3d of September, in the year 31 B.C., and in the 15th of the Julian era. By the Romans the era of Actium was considered as commencing on the 1st of January of the 16th of the Julian era, which is the 30th B.C. The Egyptians, who used this era till the time of Diocletian, dated its commencement from the beginning of their month Thoth, or the 29th of August; and the Eastern Greeks from the 2d of September. By the latter it was also called the era of Antioch, and it continued to be used till the 9th century. It must not be confounded with the Cæsarean era of Antioch, which began seventeen years earlier. Many of the medals struck by the city of Antioch in honour of Angustus are dated according to this era.
Besides the era of Actium, there was also an Augustan era, which commenced four years later, or 27 B.C., the year in which Augustus prevailed on the senate and people of Rome to decree him the title of Augustus, and to confirm him in the supreme power of the empire.

Era of Diocletian, or Era of Martyrs.

It has been already stated that the Alexandrians, at the accession of the Emperor Diocletian, made an alteration in their mundane era, by striking off ten years from their reckoning. At the same time they established a new era, which is still followed by the Abyssinians and Copts. It commences with the 29th of August (the first day of the Egyptian year) of the year 284 of our era, which was the first of the reign of Diocletian. The denomination of Era of Martyrs, subsequently given to it in commemoration of the persecution of the Christians, would seem to imply that its commencement ought to be referred to the year 303 of our era, for it was in that year that Diocletian issued his famous edict; but the practice of dating from the accession of Diocletian has prevailed. The ancient Egyptian year consisted of 365 days; but after the introduction of the Julian calendar, the astronomers of Alexandria adopted an intercalary year, and added six additional days instead of five to the end of the last month of every fourth year. The year thus became exactly similar to the Julian year. The Egyptian intercalary year, however, does not correspond to the Julian leap year, but is the year immediately preceding; and the intercalation takes place at the end of the year, or on the 29th of August. Hence the first three years of the Egyptian intercalary period commence on the 29th of our August, and the fourth commences on the 30th of that month. Before the end of that year the Julian intercalation takes place, and the beginning of the following Egyptian year is restored to the 29th of August. Hence to reduce a date according to this era to our own reckoning, it is necessary, for common years, to add 283 years and 240 days; but if the date belongs to the first three months of the year following the intercalation, or, which is the same thing, if in the third year of the Julian cycle it falls between the 30th of August and the end of the year, we must add 283 years and 241 days. The Ethiopians do not reckon the years from the beginning of the era in a consecutive series, but employ a period of 532 years, after the expiration of which they again begin with 1. This is the Dionysian or Great Paschal Period, and is formed by the multiplication of the numbers 28 and 19, that is, of the solar and lunar cycles, into each other.
The following are the names of the Ethiopian or Abyssinian months, with the days on which they begin in the Julian calendar, or old style;—

Masearam. 29th August. Magabit. 25th February.
Tikmith. 28th September. Miazia 27th March.
Hadar 28th October. Gimbot 26th April.
Tacsam 27th November. Sene 26th May.
Tir 27th December. Hamle 25th June.
Yacatit 26th January. Nahasse 25th July.

The additional or epagomenal days begin on the 24th of August. In intercalary years the first seven months commence one day later. The Egyptian months, followed by the modern Copts, agree with the above in every respect excepting the names.


The cycle of Indiction, already explained at p. 670 of vol. iv., was very generally followed in the Roman empire for some centuries before the adoption of the Christian era. Three Indictions may be distinguished; but they differ only in regard to the commencement of the year.
1. The Constantinopolitan Indiction, like the Greek year, commenced with the month of September. This was followed in the Eastern empire, and in some instances also in France.
2. The Imperial or Constantinian Indiction is so called because its establishment is attributed to Constantine. This was also called the Cæsarean Indiction. It commences on the 24th of September. It is not unfrequently met with in the ancient chronicles of France and England.
3. The Roman or Pontifical Indiction began on the 25th of December or 1st of January, according as the Christian year was held to commence on the one or other of these days. It is often employed in papal bulls, especially after the time of Gregory VII., and traces of its use are found in early French authors.

Era of the Armenians.

The epoch of the Armenian era is that of the Council of Tiben, in which the Armenians consummated their schism from the Greek Church by condemning the acts of the Council of Chalcedon; and it corresponds to Tuesday, the 9th of July of the year 552 of the Incarnation. In their civil affairs the Armenians follow the ancient vague year of the Egyptians; but their ecclesiastical year, which begins on the 11th of August, is regulated in the same manner as the Julian year, every fourth year consisting of 366 days, so that Easter and the other festivals are retained at the same place in the seasons as well as in the civil year. The Armenians also make use of the mundane era of Constantinople, and sometimes conjoin both methods of computation in the same documents. In their correspondence and transactions with Europeans, they generally follow the era of the Incarnation, and adopt the Julian year.
To reduce the civil dates of the Armenians to the Christian era, proceed as follows. Since the epoch is the 9th of July, there were 176 days from the beginning of the Armenian era to the end of the year 552 of our era; and since 552 was a leap year, the year 553 began a Julian intercalary period. Multiply, therefore, the number of Armenian years elapsed by 365; add the number of days from the commencement of the current year to the given date; subtract 176 from the sum, and the remainder will be the number of days from the 1st of January 553 to the given date. This number of days being reduced to Julian years, add the result to 552, and the sum gives the day in the Julian year, or old style.
In the ecclesiastical reckoning the year begins on the 11th of August. To reduce a date expressed in this reckoning to the Julian date, add 551 years, and the days elapsed from the 1st of January to the 10th of August, both inclusive, of the year 552,—that is to say (since 552 is a leap year), 223 days. In leap years, one day must be subtracted if the date falls between the 1st of March and 10th of August.
The following are the Armenian ecclesiastical months with their correspondence with those of the Julian calendar:—

1. Navazardi begins... 11th August.
2. Hori 10th September.
3. Sahomi 10th October.
4. Dre Thari 9th November.
5. Kagoths 9th December.
6. Aracz 8th January.
7. Malegi 7th February.
8. Arcki 9th March.
9. Angi 8th April.
10. Mariri 8th May.
11. Marcacz 7th June.
12. Herodiez 7th July.

To complete the year, five complementary days are added in common years, and six in leap years.

The Mahometan Era, or Era of the Hegira.

The era in use among the Turks, Arabs, and other Mahometan nations is that of the Hegira or Hejra, the flight of the prophet from Mecca to Medina, 622 A.D. Its commencement, however, does not, as is sometimes stated, coincide with the very day of the flight, but precedes it by sixty-eight days. The prophet, after leaving Mecca, to escape the pursuit of his enemies, the Koreishites, hid himself with his friend Abubekr in a cave near Mecca, and there lay for three days. The departure from the cave and setting out on the way to Medina is assigned to the ninth day of the third month, Rabia I.—corresponding to the 22d of September of the year 622 A.D. The era begins from the first day of the month of Moharram preceding the flight, or first day of that Arabian year, which coincides with Friday, July 16, 622 A.D. It is necessary to remember that by astronomers and by some historians the era is assigned to the preceding day, July 15. It is stated by D'Herbelot that the era of the Hegira was instituted by Omar, the second caliph, in imitation of the Christian era of the martyrs. (For details of the Mahometan year, names and length of months, and for the method of reduction of Mahometan dates to Christian, see vol. iv. pp. 679–681).

Era of Yezdegird, or Persian or Gelalæan Era.

This era commences with the elevation of Yezdegird III. to the throne of Persia, on the 16th of June in the year of our era 632. Till the year 1079 the Persian year resembled that of the ancient Egyptians, consisting of 365 days without intercalation; but at that time the Persian calendar was reformed by Gelal-ed-din Malek Shah, sultan of Khorasau, and a method of intercalation adopted which, though less convenient, is considerably more accurate than the Julian. The intercalary period is 33 years,—one day being added to the common year seven times successively at the end of four years, and the eighth intercalation being deferred till the end of the fifth year (see vol. iv. p. 667). This era was at one period universally adopted in Persia, and it still continues to be followed by the Parsees of India. The months consist of thirty days each, and each day is distinguished by a different name. According to Alfergani, the names of the Persian months are as follows:—

Afrudin-meh. Merded-meh. Adar-meh.
Ardisascht-meh. Schaharir-meh. Di-meh.
Cardi-meh. Mahar-meh. Behen-meh.
Tir-meh. Aben-meh. Affirer-meh.

The five additional days (in intercalary years six) are named Musteraca.
As it does not appear that the above-mentioned rule of intercalation was ever regularly followed, it is impossible to assign exactly the days on which the different years begin. In some provinces of India the Parsees begin the year with September, in others they begin it with October. We have stated that the era began with the 16th June 632. But the vague year, which was followed till 1079, anticipated the Julian year by one day every four years. In 447 years the anticipation would amount to about 112 days, and the beginning of the year would in consequence be thrown back to near the beginning of the Julian year 632. To the year of the Persian era, therefore, add 631, and the sum will be the year of our era in which the Persian year begins.

Chinese Chronology.

From the time of the Emperor Yaou, upwards of 2000 years B.C., the Chinese had two different years,—a civil year, which was regulated by the moon, and an astronomical year, which was solar. The civil year consisted in general of twelve months or lunations, but occasionally a thirteenth was added, in order to preserve its correspondence with the solar year. Even at that early period the solar or astronomical year consisted of 3651/4 days, like our Julian year; and it was arranged in the same manner, a day being intercalated every fourth year.
According to the missionary Gaubil, the Chinese divided the day into 100 ke, each ke into 100 minutes, and each minute into 100 seconds. This practice continued to prevail till the 17th century, when, at the instance of the Jesuit Schall, president of the tribunal of mathematics, they adopted the European method of dividing the day into twenty-four hours, each hour into sixty minutes, and each minute into sixty seconds. The civil day commences at midnight and ends at the midnight following.
Since the accession of the emperors of the Han dynasty, 206 B.C., the civil year of the Chinese has begun with the first day of that moon in the course of which the sun enters into the sign of the zodiac which corresponds with our sign Pisces. From the same period also, they have employed, in the adjustment of their solar and lunar years, a period of nineteen years, twelve of which are common, containing twelve lunations each, and the remaining seven intercalary, containing thirteen lunations. It is not, however, precisely known how they distributed their months of thirty and twenty-nine days, or, as they termed them, great and small moons. This, with other matters appertaining to the calendar, was probably left to be regulated from time to time by the mathematical tribunal.
The Chinese divide the time of a complete revolution of the sun with regard to the solstitial points into twelve equal portions, each corresponding to thirty days, ten hours, thirty minutes. Each of these periods, which is denominated a tsëĕ, is subdivided into two equal portions called chung-ki and tsie-ki, the chung-ki denoting the first half of the tsëĕ, and the tsie-ki the latter half. Though the tsëĕ are thus strictly portions of solar time, yet, what is remarkable, though not peculiar to China, they give their name to the lunar months, each month or lunation having the name of the chung-ki or sign at which the sun arrives during that month. As the tsëĕ is longer than a synodic revolution of the moon, the sun cannot arrive twice at a chung-ki during the same lunation; and as there are only twelve tsëĕ, the year can contain only twelve months having different names. It must happen sometimes that in the course of a lunation the sun enters into no new sign; in this case the month is intercalary, and is called by the same name as the preceding month.
For chronological purposes, the Chinese, in common with some other nations of the east of Asia, employ cycles of sixty, by means of which they reckon their days, moons, and years. The days are distributed in the calendar into cycles of sixty, in the same manner as ours are distributed into weeks, or cycles of seven. Each day of the cycle has a particular name, and as it is a usual practice, in mentioning dates, to give the name of the day along with that of the moon and the year, this arrangement affords great facilities in verifying the epochs of Chinese chronology. The order of the days in the cycle is never interrupted by any intercalation that may be necessary for adjusting the months or years. The moons of the civil year are also distinguished by their place in the cycle of sixty; and as the intercalary moons are not reckoned, for the reason before stated, namely, that during one of these lunations the sun enters into no new sign, there are only twelve regular moons in a year, so that the cycle is renewed every five years. Thus the first moon of the year 1873 being the first of a new cycle, the first moon of every sixth year, reckoned backwards or forwards from that date, as 1868, 1863, &c., or 1877, 1882, &c., will also commence a new lunar cycle of sixty moons. In regard to the years, the arrangement is exactly the same. Each has a distinct number or name which marks its place in the cycle, and as this is generally given in referring to dates, along with the other chronological characters of the year, the ambiguity which arises from following a fluctuating or uncertain epoch is entirely obviated. The present cycle began in the year 1864 of our era; the year 1876 is consequently the 13th of the current cycle.
The cycle of sixty is formed of two subordinate cycles or series of characters, one of ten and the other of twelve, which are joined together so as to afford sixty different combinations. The names of the characters in the cycle of ten, which are called celestial signs, are—

1. Keă; 2. Yĭh; 3. Ping; 4. Ting; 5. Woo;
6. Ke; 7. Kăng; 8. Sin; 9. Jin; 10. Kwei;

and in the series of 12, denominated terrestrial signs,

1. Tsze; 2. Chow; 3. Yin; 4. Maou; 5. Shin; 6. Sze;
7. Woo; 8. We; 9. Shin; 10. Yew; 11. Seŭh; 12. Hae.

The name of the first year, or of the first day, in the sexagenary cycle is formed by combining the first words in each of the above series; the second is formed by combining the second of each series, and so on to the tenth. For the next year the first word of the first series is combined with the eleventh of the second, then the second of the first series with the twelfth of the second, after this the third of the first series with the first of the second, and so on till the sixtieth combination, when the last of the first series concurs with the last of the second. Thus Keă-tsze is the name of the first year, Yĭh-chow that of the second, Keă-seuh that of the eleventh, Yĭh-hae that of the twelfth, Ping-tsze that of the thirteenth, and so on. The order of proceeding is obvious.
In the Chinese history translated into the Tatar dialect by order of the emperor Kang-he, who died in 1721, the characters of the cycle begin to appear at the year 2357 B.C. From this it has been inferred that the Chinese empire was established previous to that epoch; but it is obviously so easy to extend the cycles backwards indefinitely, that the inference can have very little weight. The characters given to that year 2357 B.C. are Keă-shin, which denote the 41st of the cycle. We must, therefore, suppose the cycle to have begun 2397 B.C., or forty years before the reign of Yaou. This is the epoch assumed by the authors of L'Art de Vérifier les Dates. The mathematical tribunal has, however, from time immemorial counted the first year of the first cycle from the eighty-first of Yaou, that is to say, from the year 2277 B.C.
Since the year 163 B.C. the Chinese writers have adopted the practice of dating the year from the accession of the reigning emperor. An emperor, on succeeding to the throne, gives a name to the years of his reign. He ordains, for example, that they shall be called Ta-te. In consequence of this edict, the following year is called the first of Ta-te, and the succeeding years the second, third, fourth, &c., of Ta-te, and so on, till it pleases the same emperor or his successor to ordain that the years shall be called by some other appellation. The periods thus formed are called by the Chinese Nien-hao. According to this method of dating the years a new era commences with every reign; and the year corresponding to a Chinese date can only be found when we have before us a catalogue of the Nien-hao, with their relation to the years of our era.
The Chinese chronology is discussed with ample detail by Freret, in the Memoirs of the Academy of Inscriptions, tom. xviii.; and an abridgment of his memoir is given in L'Art de Vérifier les Dates (tom. ii. p. 284, et seq.; ed. in 4to, 1818), from which the preceding account is principally taken.

Indian Chronology.

The method of dividing and reckoning time followed by the various nations of India resembles in its general features that of the Chinese, but is rendered still more complex by the intermixture of Mahometan with Hindu customs. Like the Chinese, the Hindus have a solar year, which is generally followed in the transaction of public business, especially since the introduction of European power; and they have also a lunar year, which regulates their religious festivals, and which they follow in their domestic arrangements. Their solar year, or rather sidereal year, is measured by the time in which the sun returns to the same star, and is consequently longer than our astronomical year, by the whole quantity of the precession of the equinoxes. It is reckoned by the Hindus at 365 days, 6 hours, 12 minutes, 30 seconds, and consequently exceeds a Gregorian year by one day in sixty years. The Indian zodiac is divided into twelve solar and twenty-eight lunar signs; and the year begins with the sun's arrival at the first degree of the first sign. The month is the time the sun takes to pass through one sign; and as each sign contains the same number of degrees, the months vary somewhat in length, according as the sun is nearer the apogee or the perigee. The longest month may contain 31 days, 14 hours, 39 minutes, and the shortest only 29 days, 8 hours, 21 minutes. The civil months, however, depend solely on the moon; though, with the same perversion of ingenuity which we have already remarked with regard to the Chinese, and of which it would be difficult to find an example except in the east of Asia, they derive their names from the solar signs of the zodiac. The first civil month commences with the day after the full moon of that lunation in the course of which the sun enters the first Hindu sign, and so on with the others. When the sun enters into no new sign during the course of a lunation, the month is intercalary, and is called by the name of that which precedes or follows it, which some prefix to distinguish it from the regular month. In some provinces of India, as in Bengal, the civil mouth commences with the day after the new moon; but in the upper or northern provinces, it begins, as we have stated, with the day after the full moon. From the manner in which they are reckoned, it is evident that the Hindu months, both solar and lunar, neither consist of an entire number of days, nor are regulated by any cycle, but depend solely on the motion of the sun and moon. The time of their commencement is different on every different meridian; and a Hindu has no means of knowing beforehand on what day any month begins, excepting by consulting his almanac. The civil day in all parts of India begins at sunrise.
The Hindu eras have been the subject of much controversy. According to the dreams of Indian mythology, the duration of the world is limited to four yugs or ages, three of which have already passed, and the fourth, which is the kali-yug, is the last and most deteriorated. It is this only which has any reference to authentic chronology. It forms the principal era of India, and comprehends several others in common use, as the era of Vicramaditya, the era of Salivahana, the Bengalee era, and the cycle of sixty years.
The Kali-yug commenced in the year 3101 B.C. The year is sidereal, and begins when the sun enters the first sign of the Hindu zodiac, which at present happens about the 11th of April. Owing to the precession of the equinoxes the beginning of the year advances in the seasons at the rate of about one day in sixty years.
The Era of Vicramaditya is reckoned from the year 57 B.C., which corresponds to 3044 of the Kali-yug. This era, the years of which are called Samvat, prevails chiefly in the higher or northern provinces of India, and in Guzerat. Its name is derived from, that of a sovereign of Malwa, who, by defeating Saka, king of Delhi, acquired possession of the principal throne of India. Whether the year from which it is reckoned was that of the accession or death of this prince is uncertain. The years are reckoned in the same manner as those of the Kali-yug; and it may be remarked of the Indian eras in general that, though some of them profess to be counted from the deaths of their kings, or other historical events, they all commence at the time the sun reaches the same point in his annual course through the zodiac.
The Era of Salivahana is the year 78 A.D., which corresponds to 3179 of the Kali-yug, and 135 of the Vicramaditya. The name is derived from Salivahan, who is said to have reigned many years over the kingdom of Narsinga, and to have been a liberal encourager of the arts and sciences. It is generally used in records or writings of importance, but is most prevalent in the southern provinces of Hindustan. The years are called Saka.
The Fuslee Era, from the near coincidence of its dates with those of the Hegira, seems to have been imposed on the natives of India by their Mahometan conquerors. It is principally used in revenue transactions, and is pretty generally known over India. There are several eras of this name; but the most common is that which is reckoned from the year 590 A.D. At Madras the commencement of the Fuslee year is fixed on the 12th of July. In Bengal it begins in September, or with the full moon preceding the autumnal equinox.
The Bengalee Era is also supposed to be derived from the Hegira; but the year is measured by solar time, and therefore differs entirely from the Mahometan year, which is purely lunar. At the present time the Bengalee epoch is about nine years later than the Hegira,—the year 1245 of the Hegira having commenced in July 1829, and the Bengalee year 1236 in April 1829. The sidereal year exceeds the lunar year by 10 days 211/2 hours nearly; consequently, by reckoning backwards, it will be found that the dates of the Bengalee era and of the Hegira coincided about the middle of the 16th century. History is silent on the subject; but it seems probable, that though the epoch of the Hegira was partially adopted in India, the Hindus pertinaciously resisted all attempts to disturb their ancient methods of reckoning the subdivisions of the year.
Besides the Indian eras here enumerated, there are some others which are less generally known, or which are followed only in particular provinces. The cycle of sixty years is also sometimes used, particularly in connection with the era of Vicramaditya. According to the Bengal account, the first cycle began 3185 years B.C.; and the year 1876 of our era is consequently the twenty-first of the eighty-fifth cycle. In the Telinga account the first cycle began 3114 B.C.; and the year 1876 is the tenth of the eighty-fourth cycle.
Fuller information regarding Indian chronology will be found in Prinsep's Essays on Indian Antiquities (1858), vol. ii., Warren's Kala Sankalita (1825), and Burnett's Elements of South Indian Palæography (1874).

Principal Works on Chronology.

To meet the wants of those who may desire to enter more fully into chronological studies, we subjoin a list of the leading works on the subject. In addition to the early Greek writings already named, there are the forty books (some fifteen only extant in their entirety) of universal history compiled (about 8 B.C.) by Diodorus Siculus, and arranged in the form of annals; the Pentabiblos of Julius Africanus (about 220-230 A.D.); the treatise of Censorinus entitled De die natali, written 238 A.D.; the Chronicon, in two books, of Eusebius Pamphili, bishop of Cæsarea (about 325 A.D.), distinguished as the first book of a purely chronological character which has come down to us; and three important works forming parts of the Corpus Scriptorum Historiæ Byzantinæ, namely, the Chronographia of Georgius Syncellus (800 A.D.), the Chronographia of Johannes Malalas (9th century), and the Chronicon Paschale.

Chronological Table

Of the principal events of political and military history, with notices of great men and famous books, and of the most important inventions and discoveries, from the earliest times to the close of the year 875.

Chronological tables, however unattractive to minds whose inclinations or occupations do not lie in the direction of them, are of much value and real interest for those who have knowledge and occasion to make a right use of them. To the historical student they not only serve as a storehouse of individual facts with dates, but by the orderly juxtaposition and sequence of these they indicate relations. They are maps on which are delineated or suggested the lines of the main currents in the ocean of human history. When the student, engaged on any special series of events, desires to find their place and surroundings in world-history, he has but to turn to such tables, and a glance or two will inform him.
In the preparation of the subjoined table great pains have been taken to bring it as closely as possible into agreement with the results of recent historical and chronological determinations. Events and dates of purely legendary character, once accepted as historical facts with unquestioning acquiescence, have no place in it; and the whole has been subjected to a searching examination and comparison with the best sources of information. The conflict of the authorities makes absolute certainty in many cases unattainable. The reader will therefore remember in using the table, that, as differences and authorities cannot be given, the dates are necessarily in some cases approximate or probable only.
