This Dorotheus and his contemporary, Lucian (mentioned below, in Bk. VIII. chap. 13), are the earliest representatives of the sound critical method of Biblical exegesis, for which the theological school at Antioch was distinguished, over against the school of Alexandria, in which the allegorical method was practiced. From Bk. VIII. chap. 6 we learn that Dorotheus suffered martyrdom by hanging early in the Diocletian persecution, so that it must have been from this emperor, and not from Constantine, that he received his appointment mentioned just below. Diocletian, before he began to persecute, had a number of Christian officials in his household, and treated them with considerable favor.
