A small group of Ottonian monasteries received direct sponsorship from the Emperor and bishops and produced some magnificent medieval illuminated manuscripts, the premier art form of the time. Corvey produced some of the first manuscripts, followed by the scriptorium at Hildesheim after 1000. The most famous Ottonian scriptorium was at the island monastery of Reichenau on Lake Constance: hardly any other works have formed the image of Ottonian art as much as the miniatures which originated there. One of the greatest Reichenau works was the Codex Egberti, containing narrative miniatures of the life of Christ, the earliest such cycle, in a fusion of styles including Carolingian traditions as well as traces of insular and Byzantine influences. Other well known manuscripts included the Reichenau Evangeliary, the Liuther Codex, the Pericopes of Henry II, the Bamberg Apocalypse and the Hitda Codex.
