A creative, independent, Irish exegetical tradition was well established by the year 700 CE, influencing Northumbria but not Continental Europe. This book contains eight studies by the distinguished Irish biblical scholar, Martin McNamara, which he has published over the past twenty-five years, on the Latin biblical texts (Vulgate, Gallicanum and Jerome's Hebraicum) of the Psalter and commentaries on it in Ireland from 600 CE onwards. The oldest Irish Vulgate text, the Cathach of St Columba of Iona (died 597), shows signs of correction against the Irish recension of the Hebrew text. The central exegetical tradition is strongly Antiochene, being dependent on the commentary of Theodore of Mopsuestia (in Julian's translation), while another branch understands the Psalms as principally about David, rather than christologically or as about later Jewish history.
