This second-century Ebionite* is remembered primarily for his translation of the Hebrew OT into Greek. The translation was readable, but it lacked verbal accuracy and thus the extant fragments of his work have been of little value to textual critics, although Origen* did incorporate Symmachus's work into his Hexapla. He was particularly offended at the many anthropomorphic expressions in the OT and promptly removed them. He is referred to in Eusebius's Ecclesiastical History.
