a Cynic philosopher who acquired great influence over the mind of the emperor Aurelius. While the other schools of philosophers looked down with contempt on the Christians, the Cynics had been more favorably inclined towards them; but Justin Martyr having offended Crescens by some remarks he made against him in an apology addressed to the emperor, Crescens swore to be revenged, and, to accomplish his purpose, incited the emperor to persecute the Christians. Justin Martyr was one of the victims of this persecution. (See JUSTIN MARTYR).
