The Last Judgement was normally shown on the western wall, with a Christ in Majesty in the apse semi-dome. Extensive narrative cycles of the Life of Christ were developed, and the Bible, with the Psalter, became the typical focus of illumination, with much use of historiated initials. Metalwork, including decoration in enamel, became very sophisticated, and many spectacular shrines made to hold relics have survived, of which the best known is the Shrine of the Three Kings at Cologne Cathedral by Nicholas of Verdun and others (ca 1180–1225).
