Couronne de saint Étienne
There are three small holes on each of the two side stone-plates from which probably hung chains with pendant jewels, known as "pendilia". These were a feature of the now-lost crown of Byzantine emperors, as in the mosaic portrait of Justinian I in the Basilica of San Vitale in Ravenna. Pendilia are still extant on the Holy Crown of Hungary, or the Crown of Constance of Aragon held in Palermo Cathedral.
