Cerdo (Cerdon)

CERDO (CERDON): A Syrian Gnostic, who, according to Irenæus (I. xxvii. 1, III. iv. 3) and Eusebius (Chron., ed. Schoene, i. 168), lived in Rome in the time of the bishop Hyginus (c. 136–140). Epiphanius (xli. 1) connects him with Saturninus. He is of importance chiefly as having been the teacher of Marcion.
