Duns Scotus, owing largely to the prominence of the latter as champion of the Immaculate Con- ception in the disputes between the Franciscans and Dominicans. Sixtus V, howe\-er, founded a special chair at Rome for tlie study of St. Bona- venture; such chairs also existed in several uni- versities, notably at Ingolstadt, Salzburg, Valencia, and Osuna. It is worthy of note that the Capuchins forbade their Friars to follow Scotus and ordered them to return to the study of Bonaventure. The centenary celebrations of 1874 appear to have revived interest in the life and work of St. Bona- venture. Certain it is that since then the study of his WTitings has steadily increased.
Unfortunately not all of Bonaventure's WTitings have come dowTi to us. Some were lost before the invention of printing. On tlie other hand, several works have in the course of time been attributed to him which are not his. Such are the "Centiloquium", the "Speculum Disciplinae", which is probably the work of Bernard of Besse, Bonaventure's secretarj^; the rhythmical "Philomela", which seems to be from the pen of John Peckham; the "Stimulus Amoris" and the "Speculum B. M. V.", written respectively by James of Milan and Conrad of Saxony; "The Legend of St. Clare", which is by Thomas of Celano; the "Meditationes vitte Christi" composed by a Friar Minor for a Poor Clare, and the " Biblia pau- perum" of the Dominican Nicholas of Hanapis. Those familiar with the catalogues of European libraries are aware that no writer since the Middle Ages had been more widely read or copied than Bonaventure. The earliest catalogues of his works are those given by Salimbene (1282), Henry of Cdient (d. 1293), Ubertino of Casale (1305), Ptolemy of Lucca (1327) and the "Chronicle of the XXIV Cienerals" (1368). The fifteenth century saw no less than fifty editions of Bonaventure's works. More celebrated than any preceding edition was that published at Rome (1588-96) by order of Sixtus V (7 vols, in fol.). It was reprinted with but slight emendations at Metz in 1609 and at Lyons in 1678. A fourth edition appeared at Venice (13 vols, in 4to) 1751, and was reprinted at Paris in 1864. All these editions were ^'ery imperfect in so far as they in- clude spurious works and omit genuine ones. They have been completely superseded by the celebrated critical edition published by the Friars Minor at Quaracchi, near Florence. Any scientific study of Bonaventure must be based upon this edition, upon which not only Leo XIII (13 December, 1885) and Pius X (11 April, 1904). but scholars of all creeds have lavished the highest encomiums. Nothing seems to have been omitted which could make this edition perfect and complete. In its preparation the editors visited over 400 libraries and examined nearly 52,000 MSS. while the first volume alone ^•ontains 20,000 variant readings. It was com- menced by Father Fidelis a Fanna (d. ISSl) and ■completed by Father Ignatius Jeiler (d. 1904): ■"Doctoris Seraphici S. Bonaventura; S. R. E. Epis- copi Cardinalis Opera Omnia, edita studio et cura P. P. Collegii S. Bonaventura; in fol. ad Claras Aquas [Quaracchi] 1882-1902". In this edition the works of tlie .saint are distributed througli the ten volumes as follows: the first four contain his great "Com- mentaries on the Book of Sentences"; the fifth com- prises eight smaller scholastic works such as the " Brevilonuium " and ' Itinerarium"; the sixth and
seventli are devoted to his commentaries on Scrip- ture; the eighth contains his mystical and ascetic writings and works having special reference to the order; the ninth his sermons; whilst the tenth is taken up witli the index and a short sketch of the saint's life and writings by Father Ignatius Jeiler.
We do not possess any formal, contemporary biography of St. Bonaventure. That written by
the Spanish Franciscan, Zamorra, who flourished before 1300, has not been preserved. The references to Bonaventure's life contained in the works of Salimbene (1282), Bernard of Besse (c. 1380) Bl. Francis of Fabriano (d. 1322), AngeloClareno (d. 1337), Ubertino of Casale (d. 1338), Bartliolomew of Pisa (d. 1399) and the "Clironicle of the XXIV Generals" (c. 1368), are given in vol. X of the Quaracchi Edition (pp. 39-72).

He was a member of the illustrious family to which had belonged Gregorj' XIII, the reformer of the calendar. He studied mathematics and physics un- der Santucci and became known as a prolific writer on mathematical and historical subjects. At an early age (1840) he contributed to the "Giornale Ar- cadico" biographical sketches of Father Joseph Calandrelli, director of the observatory of the Roman College after the suppression of the Society of Jesus, and his assistant Conti. These were followed by his "Recherches sur les integrales d^finies", which ap- peared in "Crelle's Journal" (Berlin). In 1846 the "Giornale Arcadico" published his "Studi intorno ad alcuni avanzamenti della fisica in Italia net secoli
