The large bronze candelabrum in the left transept is said to be 13th century work.
One type took the form of a candelabrum with a small flat brazier on the top. They were carried in processions and were lifted by cords.
The first specimen of the apparatus found at Perugia resembles a candelabrum on a base, tapering towards the top, with a blunt end, on which the small disk (found near the rod), which has a hole near the edge and is slightly hollow in the middle, could be balanced.
The interior is in the form of a basilica, the double aisles being borne by ancient columns, and contains ambones and a candelabrum of 1311, the former resting on columns supported by lions, and decorated with reliefs and coloured marble mosaic. The castle at the highest point of the town was erected in the 14th century.
On some pages these micrographic bands form a candelabrum, a motif that was mainly used in 14th century Catalan Bibles.
