Canonical Scope
The Vulgate canon, as affirmed by the Council of Trent, includes 72 books: 45 in the Old Testament and 27 in the New Testament. This canon incorporated deuterocanonical books, which were part of the Vetus Latina tradition but not found in the Hebrew Bible.
The Psalter Versions
The Book of Psalms saw multiple Latin versions associated with Jerome. The Versio Romana, a revision of an earlier Vetus Latina, was the first attempt. This was followed by the Versio Gallicana, a translation from the Greek Hexapla Septuagint, which became the most common version. Jerome also produced a Versio juxta Hebraicum, a translation directly from the Hebrew.
Textual Variants
Like other ancient texts, Vulgate manuscripts exhibit variations due to scribal practices. Efforts were made throughout history to standardize and purify the text, leading to various editions and scholarly attempts to reconstruct Jerome's original work.
