 As cities became more crowded, bones were sometimes recovered after a period, and placed in ossuaries where they might be arranged for artistic effect, as at the Capuchin Crypt in Rome or the Czech Sedlec Ossuary, which has a chandelier made of skulls and bones.The church struggled to eliminate the pagan habits of leaving grave goods except for the clothing and usual jewellery of the powerful, especially rings.Kings might be buried with a sceptre, and bishops with a crozier, their respective symbols of office.
