Sacramentarium, so called of Robert de Jumièges England, 11th century (early). 228 f. 332 x 225 mm. Bibliothèque municipale de Rouen, ms. 274 ( Y 6)

This sumptuous manuscript was given to its abbey of origin by Robert de Jumièges, when he was still Bishop of London (1044-1050), as is noted in an inscription at the head of the volume. As a key example of the school known as the Winchester school, it is illustrated with thirteen full-page paintings, arranged in very characteristic frames, frequently imitated in the 11^th century by Norman illuminators. This manuscript, with others of the same style, played a crucial role in the artistic training of the Norman monks of this period.
