the Western text-type. Comparison of Jerome's Gospel texts with those in Vetus Latina witnesses, suggests that his revision was concerned with substantially redacting their expanded "Western" phraseology in accordance with the Greek texts of better early Byzantine and Alexandrian witnesses. One major change Jerome introduced was to re-order the Latin Gospels. Most Vetus Latina gospel books followed the "Western" order of Matthew, John, Luke, Mark; Jerome adopted the "Greek" order of Matthew, Mark, Luke, John. His revisions became progressively less frequent and less consistent in the gospels presumably done later. In places Jerome adopted readings that did not correspond to a straightforward rendering either of the Vetus Latina or the Greek text, so reflecting a particular doctrinal interpretation; as in his rewording panem nostrum supersubstantialem at Matthew 6:11. The unknown reviser of the rest of the New Testament shows marked differences from Jerome, both in editorial practice and in their sources. Where Jerome sought to correct the Vetus Latina text with reference to the best recent Greek manuscripts, with a preference for those conforming to the Byzantine text-type, the Greek text underlying the revision of the rest of the New Testament demonstrates the Alexandrian text-type found in the great uncial codices of the mid-4th century, most similar to the Codex Sinaiticus. The reviser's changes generally conform very closely to this Greek text, even in matters of word order—to the extent that the resulting text may be only barely intelligible as Latin. After the Gospels, the most widely used and copied part of the Christian Bible is the Book of Psalms. Consequently, Damasus also commissioned Jerome to revise the psalter in use in Rome, to agree better with the Greek of the Common Septuagint. Jerome said he had done this cursorily when in Rome, but he later disowned this version, maintaining that copyists had reintroduced erroneous readings. Until the 20th century, it was commonly assumed that the surviving Roman Psalter represented Jerome's first attempted revision, but more recent scholarship—following de Bruyne—rejects this identification. The Roman Psalter is indeed one of at least five revised versions of the mid-4th century Vetus Latina Psalter, but compared to the other four, the revisions in the Roman Psalter are in clumsy Latin, and fail to follow Jerome's known translational principles, especially in respect of correcting harmonised readings. Nevertheless, it is clear from Jerome's correspondence (especially in his defence of the Gallican Psalter in the long
