This beautiful illuminated manuscript, now in Vienna, Osterreichische Nationalbibliothek, is one of the earliest surviving examples of a unique group of Bibles containing the most extensive cycles of biblical illustrations juxtaposed with theological and allegorical interpretative images. The present moralized Bible was produced in Paris in the first half of the 13th century, and contains over 1000 exquisitely illuminated medallions accompanied by textual extracts and commentaries that act as captions to the illustrations and thus reveal, by word and image, the relevance of the Bible to contemporary life. They reflect the rapidly-changing world of the thirteenth century and highlight the many ideological problems prominent in the intellectual and political milieu of the time. It is a book that has long fascinated both historians and art-historians, since it stands out not only as one of the major artistic achievements of its time, but also as an important historical document for an understanding of medieval Europe. All illuminated pages of Codex 2554 are reproduced in full colour in this volume. In his commentary to the manuscript, Gerald Guest explains the origins of this type of Bible manuscript; he compares the work with other surviving examples, examines the style and meaning of the illuminations, poses the likely patrons and puts the creation of the moralized Bible in its intellectual and artistic context. The author has also translated all the French texts that accompany the illuminations into English.
