Tatian (redirected from Taitian)

Tatian (tā`shən), 2d cent., Christian apologist. Probably born in Syria, he was a pupil of Justin Martyr. After his master's death, he left Christianity, becoming an Encratitic Gnostic—i.e., he regarded all matter as evil and denied the salvation of Adam. While a Christian, he wrote Oratio ad Graecos [address to the Greeks] (152–55), a defense of Christianity bolstered by a bitter attack on Greek arts, philosophers, and institutions, and the Diatessaron, a harmony of the four Gospels that was long the only life of Jesus available in Syria.
