Bishop of Heraclea, Egypt. Tortured, mutilated and crippled for his faith during the persecutions of Maximinus Daia in the early 4th century. Attended the Council of Nice in 325 and zealously opposed Arianism. Friend of Saint Athanasius whom he defended in the Council of Tyre in 335. When the Arian Gregory grabbed power in Egypt in 341, he had Potamon beaten with clubs and left for dead; Potamon received medical help, survived his inujuries for a while, but eventually died from the damage. Martyr. Athanasius wrote about his life and referred to Potamon as a “double martyr” because of the abuse he suffered in two separate persecutions.
