257. Sources and Bibllography. -- The great critical edition of St. Bonaventure's works, published at Quaracchi, 1882-1902, is a scientific monument of the highest excellence and a model of the best style ot editing scholastic works. Vols. i - iv contain the Commentaries on the Sentences. Each volume contains critical prolegomena, a critical edition of the text, and, after the principal questions, scholia which are veritable monographs on the history of the theories dealt with in the questions. Vol. v. contains eight theologico-philosophical opuscula. Vols. vi - ix. contain but little of interest to philosophy. Many portions of the text, especially the Quaestiones Disputatae (except the De Paupertate) are here published for the first time (vol. v.). The prolegomena to vol. iii. give tables of philosophical divergences of view between St. B. and St. Thomas Aquinas in their Commentaries on the Sentences. Vol. x. gives a dissertation on the life and writings of the Saint: very useful. See too a list of the principal scholia of the first four volumes -- and a study of some 108 apocryphal or doubtful writings. The scholastic side of the Saint's life and personality is excellently handled.
