Laurentian, Angelo Maria Bandini suggested that the author was Servandus, a follower of St. Benedict, and that it had been produced at Monte Cassino around the 540s. This claim was accepted for the next hundred years, establishing it as the oldest copy of the Vulgate, but scholars in Germany noted the similarity to 9th-century texts. In 1888, Giovanni Battista de Rossi established that the Codex was related to the Bibles mentioned by Bede. This also established that Amiatinus was related to the Greenleaf Bible fragment in the British Library. Although de Rossi's attribution removed 150 years from the age of the Codex, it remains the oldest complete text of the Vulgate. As the primary source of the Vulgate, the manuscript was of particular importance to the Catholics during the Counter-Reformation. Protestant translations derived from the original language of the Scriptures, but the Latin text of the Amiatinus was earlier than any then-known Hebrew manuscript, making it a "major piece of propaganda in the battle for textual precedence". In 1587 Pope Sixtus V demanded the book be sent to Rome where it was consulted for a new papal edition of the Bible, the Sixtine Vulgate; although in the event, little or no use was made of its readings in either the Sistine or subsequent Sixto-Clementine official Vulgate editions, whose editors rather preferred later medieval Vulgate texts and editions now known to have been heavily corrupted by non-Vulgate readings. In view of the many accumulated corruptions in all published editions of the Vulgate so far, the Oxford University Press accepted in 1878 a proposal from classicist John Wordsworth (later Bishop of Salisbury) to produce a new critical edition of the Vulgate New Testament. This was eventually published as Nouum Testamentum Domini nostri Iesu Christi Latine, secundum editionem sancti Hieronymi in three volumes between 1889 and 1954; the Codex Amiatinus being a primary source for the entire text; which also followed this manuscript in presenting the text in sense lines, cola et commata without any other indication of punctuation. In 1907 Pope Pius X commissioned the Benedictine monks in Rome to prepare a critical edition of Jerome's Vulgate, entitled Biblia Sacra iuxta latinam vulgatam versionem, which eventually emerged as a counterpart Old Testament to the Oxford New Testament, following largely the same critical principles, and according similar primary status to the Codex Amiatinus text (other than for the Psalms); and similarly deriving its
