The most numerous surviving works of the Carolingian renaissance are illuminated manuscripts. A number of luxury manuscripts, mostly Gospel books, have survived, decorated with a relatively small number of full-page miniatures, often including evangelist portraits, and lavish canon tables, following the precedent of the Insular art of Britain and Ireland. Narrative images and especially cycles are rarer, but many exist, mostly of the Old Testament, especially Genesis; New Testament scenes are more often found on the ivory reliefs on the covers.[3] The oversized and heavily decorated initials of Insular art were adopted, and the historiated initial further developed, with small narrative scenes seen for the first time towards the end of the period—notably in the Drogo Sacramentary.
