Throne of the Emperor of Constantinople from a 9th century Greek manuscript. The Chrysotriklinos was the main reception and ceremonial hall of the Great Palace of Constantinople from its construction, in the late 6th century, until the 10th century. Despite its prominence in Byzantine texts, no full description of it is ever given. From the fragmented literary evidence, the hall appears to have been of octagonal shape crowned by a dome. The roof was supported by 8 arches, which formed kamarai (apses or niches), and pierced by 16 windows. The imperial throne was placed on the eastern apse behind a bronze railing.
