 The candelabrum, 2.26 metres high with a span of 1.88 metres is composed of 46 individual cast bronze pieces.The candelabrum symbolises the unity of the Trinity and the Earth with its four cardinal points and the idea of Christ as the light of the World, which will lead the believers home at the Last Judgement (Book of Revelation).Other remarkable items in the Cathedral treasury include the so-called Childhood Crown of Otto III, four Ottonian processional crosses, the long-revered Sword of Saints Cosmas and Damian, the cover of the Theophanu Gospels, several gothic arm-reliquaries, the largest surviving collection of Burgundian fibulae in the world and the Great Carolingian Gospels.
