Paulof Samosata
Paul of Samosata, an heresiarch of the third century, was born at Samosata, the capital of Commagene, on the Euphrates. He became Bishop of Antioch in 262, and was supported in his heresy by Zenobia, Queen of Palmyra, who made him her chief minister. After the defeat of Zenobia by the Roman emperor Aurelian, in 272, Paul was deposed. His heresy consisted in denying the distinction of the three Persons of the Trinity.
