their special age, size, purpose, &c. Thus they include under it various dissimilar things. We may distinguish (1) Roman “camps” (castra) of three kinds, large permanent fortresses, small permanent forts (both usually built of stone) and temporary earthen encampments (see Roman Army); (2) Pre-Roman; and (3) Post-Roman camps, such as occur on many English hilltops. We know far too little to be able to assign these to their special periods. Often we can say no more than that the “camp” is not Roman. But we know that enclosures fortified with earthen walls were thrown up as early as the Bronze Age and probably earlier still, and that they continued to be built down to Norman times. These consisted of hilltops or cliff-promontories or other suitable positions fortified with one or more lines of earthen ramparts with ditches, often attaining huge size. But the idea of an artificial elevation seems to have come in first with the Normans. Their mottes or earthen mounds crowned with wooden palisades or stone towers and surrounded by an enclosure on the flat constituted a new element in fortification and greatly aided the conquest of England. (See Castle.)
CAMPAGNA DI ROMA, the low country surrounding the city of Rome, bounded on the N.W. by the hills surrounding the lake of Bracciano, on the N.E. by the Sabine mountains, on the S.E. by the Alban hills, and on the S.W. by the sea. (See Latium, and Rome (province).)
CAMPAIGN, a military term for the continuous operations of an army during a war or part of a war. The name refers to the time when armies went into quarters during the winter and literally “took the field” at the opening of summer. The word is also used figuratively, especially in politics, of any continuous operations aimed at a definite object, as the “Plan of Campaign” in Ireland during 1886–1887. The word is derived from the Latin Campania, the plain lying south-west of the Tiber, c.f. Italian, la Campagna di Roma, from which came two French forms: (1) Champagne, the name given to the level province of that name, and hence the English “champaign,” a level tract of country free from woods and hills; and (2) Campagne, and the English “campaign” with the restricted military meaning.
CAMPAN, JEANNE LOUISE HENRIETTE (1752–1822), French educator, the companion of Marie Antoinette, was born at Paris in 1752. Her father, whose name was Genest, was first clerk in the foreign office, and, although without fortune, placed her in the most cultivated society. At the age of fifteen she could speak English and Italian, and had gained so high a reputation for her accomplishments as to be appointed reader to the three daughters of Louis XV. At court she was a general favourite, and when she bestowed her hand upon M. Campan, son of the secretary of the royal cabinet, the king gave her an annuity of 5000 livres as dowry. She was soon afterwards appointed first lady of the bedchamber by Marie Antoinette; and she continued to be her faithful attendant till she was forcibly separated from her at the sacking of the Tuileries on the 20th of June 1792. Madame Campan survived the dangers of the Terror, but after the 9th Thermidor finding herself almost penniless, and being thrown on her own resources by the illness of her husband, she bravely determined to support herself by establishing a school at St Germain. The institution prospered, and was patronized by Hortense de Beauharnais, whose influence led to the appointment of Madame Campan as superintendent of the academy founded by Napoleon at Écouen for the education of the daughters and sisters of members of the Legion of Honour. This post she held till it was abolished at the restoration of the Bourbons, when she retired to Mantes, where she spent the rest of her life amid the kind attentions of affectionate friends, but saddened by the loss of her only son, and by the calumnies circulated on account of her connexion with the Bonapartes. She died in 1822, leaving valuable Mémoires sur la vie privée de Marie Antoinette, suivis de souvenirs et anecdotes historiques sur les règnes de Louis XIV.-XV. (Paris, 1823); a treatise De l’Éducation des Femmes; and one or two small didactic works, written in a clear and natural style. The most noteworthy thing in her educational system, and that which especially recommended it to Napoleon, was the place given to domestic economy in the education of girls. At Écouen the pupils underwent a complete training in all branches of housework.
CAMPANELLA, TOMMASO (1568–1639), Italian Renaissance philosopher, was born at Stilo in Calabria. Before he was thirteen years of age he had mastered nearly all the Latin authors presented to him. In his fifteenth year he entered the order of the Dominicans, attracted partly by reading the lives of Albertus Magnus and Aquinas, partly by his love of learning. He took a course in philosophy in the convent at Morgentia in Abruzzo, and in theology at Cosenza. Discontented with this narrow course of study, he happened to read the De Rerum Natura of Bernardino Telesio, and was delighted with its freedom of speech and its appeal to nature rather than to authority. His first work in philosophy (he was already the author of numerous poems) was a defence of Telesio, Philosophia sensibus demonstrata (1591). His attacks upon established authority having brought him into disfavour with the clergy, he left Naples, where he had been residing, and proceeded to Rome. For seven years he led an unsettled life, attracting attention everywhere by his talents and the boldness of his teaching. Yet he was strictly orthodox, and was an uncompromising advocate of the pope’s temporal power. He returned to Stilo in 1598. In the following year he was committed to prison because he had joined those who desired to free Naples from Spanish tyranny. His friend Naudée, however, declares that the expressions used by Campanella were wrongly interpreted as revolutionary. He remained for twenty-seven years in prison. Yet his spirit was unbroken; he composed sonnets, and prepared a series of works, forming a complete system of philosophy. During the latter years of his confinement he was kept in the castle of Sant’ Elmo, and allowed considerable liberty. Though, even then, his guilt seems to have been regarded as doubtful, he was looked upon as dangerous, and it was thought better to restrain him. At last, in 1626, he was nominally set at liberty; for some three years he was detained in the chambers of the Inquisition, but in 1629 he was free. He was well treated at Rome by the pope, but on the outbreak of a new conspiracy headed by his pupil, Tommaso Pignatelli, he was persuaded to go to Paris (1634), where he was received with marked favour by Cardinal Richelieu. The last few years of his life he spent in preparing a complete edition of his works; but only the first volume appears to have been published. He died on the 21st of May 1639.
In philosophy, Campanella was, like Giordano Bruno (q.v.), a follower of Nicolas of Cusa and Telesio. He stands, therefore, in the uncertain half-light which preceded the dawn of modern philosophy. The sterility of scholastic Aristotelianism, as he understood it, drove him to the study of man and nature, though he was never entirely free from the medieval spirit. Devoutly accepting the authority of Faith in the region of theology, he considered philosophy as based on perception. The prime fact in philosophy was to him, as to Augustine and Descartes, the certainty of individual consciousness. To this consciousness he assigned a threefold content, power, will and knowledge. It is of the present only, of things not as they are, but merely as they seem. The fact that it contains the idea of God is the one, and a sufficient, proof of the divine existence, since the idea of the Infinite must be derived from the Infinite. God is therefore a unity, possessing, in the perfect degree, those attributes of power, will and knowledge which humanity possesses only in part. Furthermore, since community of action presupposes homogeneity, it follows that the world and all its parts have a spiritual nature. The emotions of love and hate are in everything. The more remote from God, the greater the degree of imperfection (i.e. Not-being) in things. Of imperfect things, the highest are angels and human beings, who by virtue of the possession of reason are akin to the Divine and superior to the lower creation. Next comes the mathematical world of space, then the corporeal world, and finally the empirical world with its limitations of space and time. The impulse of self-
