Apologist, Bishop of Athens, “Disciple of the Apostles”. He was the first Christian apologist, and c.125 addressed a discourse to the Emperor Hadrian containing an apology for the Christian religion. This has disappeared but Eusebius states, incorrectly however, that it moved the emperor to issue a favorable edict. Quadratus is quoted in Eusebius and Jerome, and mentioned in the martyrologies. Feast, 26 May.
