The literary activity of St. Jerome, …
A first period extends to his sojourn in Rome (382), a period of preparation. From this period we have the translation of the homilies of Origen on Jeremias, Ezechiel, and Isaias (379-81), and about the same time the translation of the Chronicle of Eusebius; then the "Vita S. Pauli, prima eremitae" (374-379).
A second period extends from his sojourn in Rome to the beginning of the translation of the Old Testament from the Hebrew (382-390). During this period the exegetical vocation of St. Jerome asserted itself under the influence of Pope Damasus, and took definite shape when the opposition of the ecclesiastics of Rome compelled the caustic Dalmatian to renounce ecclesiastical advancement and retire to Bethlehem. In 384 we have the correction of the Latin version of the Four Gospels; in 385, the Epistles of St. Paul; in 384, a first revision of the Latin Psalms according to the accepted text of the Septuagint (Roman Psalter); in 384, the revision of the Latin version of the Book of Job, after the accepted version of the Septuagint; between 386 and 391 a second revision of the Latin Psalter, this time according to the text of the "Hexapla" of Origen (Gallican Psalter, embodied in the Vulgate). It is doubtful whether he revised the entire version of the Old Testament according to the Greek of the Septuagint. In 382-383 "Altercatio Luciferiani et Orthodoxi" and "De perpetua Virginitate B. Mariae; adversus Helvidium". In 387-388, commentaries on the Epistles to Philemon, to the Galatians, to the Ephesians, to Titus; and in 389-390, on Ecclesiastes.
... In 392-93, "De viris illustribus", and "Adversus Jovinianum"; in 395, commentaries on Jonas and Abdias; in 398, revision of the remainder of the Latin version of the New Testament, and about that time commentaries on chapters 13-23 of Isaias; in 398, an unfinished work "Contra Joannem Hierosolymitanum"; in 401, "Apologeticum adversus Rufinum"; between 403-406, "Contra Vigilantium"; finally from 398 to 405, completion of the version of the Old Testament according to the Hebrew.
In the last period of his life, from 405 to 420, … he commented on Osee, Joel, Amos, Zacharias, Malachias; in 408, on Daniel; from 408 to 410, on the remainder of Isaias; from 410 to 415, on Ezechiel; from 415-420, on Jeremias. From 401 to 410 date what is left of his sermons; treatises on St. Mark, homilies on the Psalms, on various subjects, and on the Gospels; in 415, "Dialogi contra Pelagianos".
