"The Biblia Sacra Vulgata originated about the year 382 A.D. Pope Damasus commissioned St Jerome to translate the original Greek and Hebrew texts into Latin." http://www.drbo.org/lvb/ , the Bible on which both the King James Version, and the
Douay Rheims bible would eventually be based and cite for translation. It contained 73 canonical books. Jerome, objected as to whether or not the non-hebrew books found in the Septuagint Version and not the Hebrew, were in fact canonical, but submitted to the church, who had recently investigated such issues. Jerome accepted the official canon.
The Vulgate is considered one of the best Catholic bibles in existance, especially recognised at the council of trent.
