Cassiani opera. Collationes XXIIII

Johannes Cassianus (ca. 360–430), presbyter in Gaul and author of the famous De institutis coenobiorum and the Collationes, is not only one of the most important witnesses to the early period of monastic life, but also, having spent years in several monasteries in Egypt and Palestine, he was an unique intermediary between the different monastic types that developed in the Greek-speaking east and the Latin west: His influence on the Regula Benedicti for example can hardly be overestimated. His De incarnatione contra Nestorium, a work that is less well known, is nevertheless one of the main sources of our knowledge of the theology of Nestorius. Ever since it was first published the edition of all three texts by Michael Petschenig in 1886 (CSEL 13) and 1888 (CSEL 17) has rightly been regarded as an outstanding editorial achievement and has been adopted virtually unaltered even by more recent editions. The reprint of both volumes presented here faithfully reproduces the Prolegomena, the text and the critical notes of Petschenig’s edition. The indexes however have been completely reworked by deleting obsolete parts, adding a large amount of addenda especially to the so-called apparatus similium, and dividing it equally between the two volumes, hopefully making them more user-friendly.
