Other works of art such as the crowns of light (circular chandeliers) made in cast bronze, dating from the Fatimid-Zirid period (around the tenth to the early eleventh century), originally belonged to the furniture of the mosque. These polycandelons, now scattered in various Tunisian museums including Raqqada, consist of three chains supporting a perforated brass plate, which has a central circular ring around which radiate 18 equidistant poles connected by many horseshoe arches and equipped for each of two landmarks flared. The three chains, connected by a suspension ring, are each fixed to the plate by an almond-shaped finial. The crowns of light are marked by Byzantine influence to which the Kairouanese artisan brought the specificities of Islamic decorative repertoire (geometric and floral motifs).
