I think we should explain something about the Vulgate here. While popular imagination thinks that St. Jerome translated the whole Bible, in reality the Vulgate Old Testament protocanon and the gospels are the only ones we can be reasonably certain are his work. (We aren’t completely sure if he managed to complete the New Testament when he revised the gospels under Pope Damasus’ orders in 382, and if so, whether the translation included today in the Vulgate is that same one.) Certain books, such as Baruch, Sirach, Wisdom, Prayer of Manasses, Ecclesiasticus, 1-2 Maccabees, 3-4 Esdras, Epistle to the Laodiceans and perhaps the rest of the NT, are likely to be either
Vetus Latina translations either revised by somebody else or totally unrevised that were appended later to Jerome’s translation to complete the set, as it were.
Baruch is a very interesting case. Even after he apparently deferred to the Church regarding the canonicity of six of the seven disputed (by Protestants) deuterocanonicals, St. Jerome
continued to have some personal reservations regarding Baruch “which is neither read nor found among the Hebrews”, though he realized full well that he would come under some attack for his opinion. Consequently, a Vulgate version of Baruch is not found before the 9th century, and is present only in a minority of manuscripts before the 13th century. In his
Prologue to Jeremiah he says:
Besides this, the order of visions, which is entirely confused among the Greeks and Latins, we have corrected to the original truth. And the Book of Baruch, his scribe, which is neither read nor found among the Hebrews, we have omitted, standing ready, because of these things, for all the curses from the jealous, to whom it is necessary for me to respond through a separate short work. And I suffer because you think this. Otherwise, for the benefit of the wicked, it was more proper to set a limit for their rage by my silence, rather than any new things written to provoke daily the insanity of the envious.
In Italy, the 71 books as listed by St. Jerome (counting Maccabees as a single book and excluding Baruch), although not in his order, formed the standard text of the Vulgate (note: the term
versio vulgata was only applied to the translation - which originally never had a specific name - during the late Middle Ages by people like Friar Roger Bacon, when it had become the ‘commonly-used version’ in the West parallel to the
Greek Vulgate in common use among the Eastern Churches) as it became established in the 5th and 6th centuries. The case was slightly different in other areas like Spain. There the readings tended to vary much further from Jerome’s original, specifically in the retention of many Old Latin readings, in the expansion of the text of Proverbs, and in the insertion of the infamous
Comma Johanneum. Some editions here also included an Old Latin translation of ‘missing’ book of Baruch as well as 3 and 4 Esdras (aka 1 and 2 Esdras). Spanish, Italian and Irish Vulgate traditions were all reflected in bibles created in northern France, which by the end of the 8th century featured a wide variety of highly variable texts.
Because of the huge variance among the textual traditions there was a movement during the Carolingian period to standardize the text. The English scholar
Alcuin produced a version based on the Italian recensions, but with the major change of substituting Jerome’s Gallican Psalter (including Psalm 151) for his third version from the Hebrew. Alcuin’s contemporary
Theodulf of Orleans produced a second independent reformed recension of the Vulgate, also based largely on Italian exemplars, but with variant readings, from Spanish texts and patristic citations, indicated in the margin. Theodulf kept Jerome’s Hebrew Psalter, and also incorporated Baruch (and with it, the Letter of Jeremiah) within the book of Jeremiah. However, otherwise Theodulf adopted Jerome’s proposed order of the Old Testament, with the five (six) deuterocanonical books at the end.
