1 Serapion when young was a pupil of Theonas, and an anecdote of his youthful indulgence in good things in secret has been already told in II. c. xi. Another story of him is given in XVIII. xi. One of this name is mentioned by Palladius in the Lausiac History, c. lxxvi., and by Rufinus in the History of the Monks, c. xviii., where we are told that he lived at Arsinöe, and that he had ten thousand monks subject to his rule; a number which Sozemen also gives (H.E. VI. xxviii.). It is however, doubtful whether this Serapion of Arsinöe is the person whose Conference Cassian here gives. Gazet identifies, Tillemont distinguishes the two. Jerome, it should be noticed, speaks in Ep. cviii. (Epitaphium Paulae) as if there was not only one of this name famous among the monks of Egypt at that time.
