Paul was from very early days celebrated as the first of the anchorites. Indeed S. Jerome, who wrote his life (Works, Vol. ii. p. 13 ed. Migne) calls him “auctor vitæ monasticæ” (Ep. xxii. ad Eustochium). He is said to have fled to the Thebaid from the terrors of the Decian persecution, and to have died there in extreme old age. Antony has already been several times mentioned by Cassian. See the Institutes V. iv.: Conference II. ii.; III. iv., etc.
