Dorotheus a presbyter of Antioch, mentioned by Eusebius as "a man of fine taste in sacred literature, who was much devoted to the study of the Hebrew language, so that he read the Hebrew Scriptures with great facility. He also was of a very liberal mind, and not unacquainted with the preparatory studies pursued among the Greeks, but in other respects a eunuch by nature, having been such from his birth; so that the emperor, on this account, as if it were a great miracle, received him into his house and family, and honored him with an appointment over the purple dye establishment of Tyre. Him we have heard in the church expounding the Scriptures with great judgment." As Eusebius says that he flourished under Cyril, who is supposed to have been bishop of Antioch from A.D. 280 to 300, the date of Dorotheus may be given as about A.D. 290. — Eusebius, Hist.
