Talk about a bit of history. The Philoxenian version was written by Aksenāyâ Mabûḡāyâ which is probably translated as most people say Philoxenus of Mabbug.
This version started in the 5th Century by the above to be a more accurate translation of the Septuagint ( the Greek Old Testament written in long before ).
This is a Syriac Translation of the Bible but then you also get the Syriac Peshitta which is supposedly something else. It can get very confusing. The Philoxenus or Philoxenian version is based on the Peshitta as far as I know.
