From St. Gregory, (Dial. l. 2, c. 1,) who assures us that he received
his account of this saint from four abbots, the saint's disciples;
namely, Constantine, his successor at Monte Cassino, Simplicius, third
abbot of that house, Valentinian, the first abbot of the monastery of
Lateran, and Honoratus, who succeeded St. Benedict at Subiaco. See the
remarks of Mabillon, Annal. Ben. l. 1, p. 3, and l. 2, p. 38. and Act.
