Addas
From the Catholic Encyclopedia
One of the three original disciples of Manes (q.v.), who according to the Acts of Archelaus introduced the heretical teachings of Manes into Scythia and later went on a similar mission to the East, being also commissioned to collect Christian books. He is called Baddas by Cyril of Jerusalem. Photius refers to a work of his (Biblioth. Cod. 85) entitled "Modion" (Mark, iv, 21) which was refuted by Diodorus of Tarsus. A work against Moses and the Prophets by Addas and Adimantus is also mentioned.
