This article provides a description of MS 'Erfurt 1', now classified as Cod. Or. Fol. 1210-1211 at the Staatsbibliothek zu Berlin. This manuscript is a huge Hebrew and Aramaic Bible, rooted in the tradition of the giant Bibles. The creation of this Bible was finished in 1343, most probably in or in the neighbourhood of Erfurt. The consonantal text is Ashkenazi, related to MS El. f.6 at the Thüringer Universitäts- und Landesbibliothek of Jena. It also contains the text of an Ashkenazi tosefta-targum to 1 Sam. 17.8. The manuscript was severely damaged during the World War II. Restoration of the first volume is already underway.
