Theodotion (/ˌθiːəˈdoʊʃən/; Greek: Θεοδοτίων, gen.: Θεοδοτίωνος; died ca. 200) was a Hellenistic Jewish scholar, perhaps working in Ephesus, who in ca. 150 CE translated the Hebrew Bible into Greek. Whether he was revising the Septuagint, or was working from Hebrew manuscripts that represented a parallel tradition that has not survived, is debated. His finished version, which filled some lacunae in the Septuagint version of the Book of Jeremiah and Book of Job, formed one column in Origen of Alexandria's Hexapla, c. 240 CE. Theodotion's translation was so widely copied in the Early Christian church that its version of the Book of Daniel virtually superseded the Septuagint's.
