Theodotion (; /Theodotiōn) is traditionally identified as one of three major Jewish translators of the Hebrew Bible into Greek during the second century CE, alongside Aquila and Symmachus. According to Irenaeus (d. c.202 CE), Theodotion was a proselyte from Asia Minor, likely Ephesus (Adversus haereses III.23). Epiphanius dates his activity to the reign of Emperor Commodus (c.190 CE) (de Mensuris et Ponderibus §17), though this chronology may derive from the column order in Origen's Hexapla rather than historical evidence.
