Chapter five moves to the third main theme of the book, that of Aachen itself. Where earlier scholars took note of only a few sources, Sulovsky reconstructs Barbarossa’s crown chandelier, known as the Barbarossaleuchter, on the basis of findings ranging from annals, charters, liturgical books and theological literature to the visual and textual consonances of the chandelier with other parts of the Marienkirche in Aachen. This demonstrates deep traditionalism of Aachen, including the link between Aachen’s Carolingian dome mosaics, Alcuin’s commentary on the Apocalypse that was its textual counterpart and exposition, and the Barbarossaleuchter, which imitates both the dome and the commentary numerologically and visually. By using the annals of Aachen, a text barely noticed by historians, the dating of the chandelier’s inauguration is established. The chapter shows how Saladin’s emissaries were kept in attendance during Easter 1174, when the chandelier was being dedicated, so that Barbarossa could have Arabic representatives present. This was done in order to imitate Charlemagne’s cordial relationship with the Arab caliph Harun al-Rashid, who had given his Christian counterpart two golden candelabra, which Charlemagne then dedicated to the Virgin of Aachen. Thus, Frederick was not trying to sacralise the Empire, but to follow Charlemagne’s example.
