A Valentinean Gnostic Sage, possibly from Sicily, who flourished around 120? A.D. He declared that, "the orthodox church was dogmatic and like unourishing stagnant water". Origen and Clement preserved some of his commentary on the "Gospel of John", and others of which some fragments still exist. (See "Fragments of Heracleon".) http://www.sacred-texts.com/gno/fff/fff56.htm
