Very good copy of the third and last revised and extended version of the standard edition of the complete works of John Cassian. The literary history of Cassian's works is not without an interest of its own. They were held in great estimation in spite of their Semi-Pelagian doctrines. These were naturally accounted a blemish, and it is not surprising that those who most admired their excellences were anxious to avoid propagating their errors. Hence they were often expurgated, and in many mss. the text has suffered considerably from the changes made by copyists in the interests of orthodoxy. In 1616 there was published at Douay in two volumes what has remained until the present day the standard edition of Cassian's works, prepared with loving care by a Benedictine monk of the Abbey of St. Vaast at Arras, Allart Gazet (1566-1626). Besides the Institutes, Conferences, and the work on the Incarnation against Nestorius, these volumes contained the following among other material: The Rule of St. Pachomius. The Catholic doctrine substituted for the latter part of Conference XIII. by Dionysius Carthusianus. Prosper Contra Collatorem. Furthermore this edition is enriched throughout with copious annotations, containing an immense amount of illustrative matter; and besides the text of Cassian's works it contains several other documents of importance for a right understanding of them. We offer here the third and final edition of the revised and extended text by Gazet in 1 volume, containing still more illustrative material (Cf. Ceillier, Auteurs sacrés et ecclésiastiques, VIII p. 204). It still remains indispensable to the student of Cassian's works by reason of the valuable commentary with which it is throughout enriched. Only for the mere text it was superseded by the edition prepared by Petschenig for the Vienna Corpus Scriptorum Ecclesiasticorum Latinorum. Graesse, II, p. 62; BNF nr. 30203248; 4 copies in OCLC (of which 1 US). Stamp on half-title, waterstain in lower and inner margin of first 20 pages, solid and internally clean.
