Priscillianus the bishop.
Priscillianus, 2554 bishop of Abila, belonged to the party of Hydatius and Ithacius, and was put to death at Trèves by the tyrant Maximus. He published many short writings, some of which have reached us. He is still accused by some, of being tainted with Gnosticism, that is, with the heresy of Basilides or Mark, of whom Irenæus writes, while his defenders maintain that he was not at all of this way of thinking.
