St. Aristidis + Commemorated on September 13
Aristides the Athenian was a 2nd-century Christian Greek author who is primarily known as the author of the Apology of Aristides. Very little is known of Aristides, except for the introductory information given by Eusebius of Caesarea and Saint Jerome, both writing in the 4th century AD. According to their account, Aristides practiced philosophy in Athens, where he lived, prior to and after his conversion to Christianity. Eusebius writes in his Ecclesiastical History (Book 4, Ch. 3): "Aristides also, a faithful disciple of our religion, has left an Apology of the faith dedicated to Hadrian."
