Aristides

, an Athenian philosopher, became a convert to Christianity in the second century, and wrote “An Apology for the Christian faith,” which, at the same time with Quadratus, he presented to the emperor Adrian. It is not now extant, but is mentioned by Jerom and by Eusebius who had probably seen it. Jerom adds, that after he was converted he continued to wear the habit of a philosopher. He speaks very highly of the learning displayed in the “Apology,” which Justin imitated in the book he presented to Antoninus Pius, and his sons, and the Roman senate. ²
