22 There was in Egypt one Scythianus, a Saracen by birth, having nothing in common either with Judaism or with Christianity. This man, who dwelt at Alexandria and imitated the life of Aristotle, composed four books, one called a Gospel which had not the acts of Christ, but the mere name only, and one other called the book of Chapters, and a third of Mysteries, and a fourth, which they circulate now, the Treasure. This man had a disciple, Terebinthus by name. But when Scythianus purposed to come into Judæa, and make havoc of the land, the Lord smote him with a deadly disease, and stayed the pestilence.
