Tyrannius Rufinus
Of the original twenty-five books in Origen's "Commentary on the Gospel of Matthew", only eight have survived in the original Greek (Books 10–17), covering Matthew 13.36–22.33. An anonymous Latin translation beginning at the point corresponding to Book 12, Chapter 9 of the Greek text and covering Matthew 16.13–27.66 has also survived. The translation contains parts that are not found in the original Greek and is missing parts that are found in it. Origen's "Commentary on the Gospel of Matthew" was universally regarded as a classic, even after his condemnation, and it ultimately became the work which established the Gospel of Matthew as the primary gospel. Origen's "Commentary on the Epistle to the Romans" was originally fifteen books long, but only tiny fragments of it have survived in the original Greek. An abbreviated Latin translation in ten books was produced by the monk Tyrannius Rufinus at the end of the fourth century. The historian Socrates Scholasticus records that Origen had included an extensive discussion of the application of the title "theotokos" to the Virgin Mary in his commentary, but this discussion is not found in Rufinus's translation, probably because Rufinus did not approve of Origen's position on the matter, whatever that might have been.
