David St

David, St. (about 601), the patron saint of Wales, was first Archbishop of Caerleon, and then of Menevia (now St. David's). Not much is known of him, though legends speak of his piety, of his energetic opposition to Pelagianism, and of miracles wrought at his tomb. He is said to have written some theological treatises.
