ATHENAGORAS, an Athenian philosopher who flourished about the middle of the second century. Originally a disciple of Plato, he embraced Christianity, and distinguished himself by the zeal and learning which he brought to its defence. Two of his works are extant—an Apology for Christianity, addressed to the Emperors Marcus Aurelius Antoninus and Lucius Commodus, and a Treatise on the Resurrection. The best edition of his works is that of the Benedictines, published at Paris in 1742, together with the writings of Justin Martyr, Theophilus of Antioch, and Hermias, in one vol. folio. There is also an English translation by Humphreys, London, 1714.
