San Silvestro in Capite
He was originally buried in the Catacombs of San Callisto and the inscription by Damasus was placed later on his tomb. Some time later his relics were moved to the San Silvestro in Capite church in Rome. His feast day is celebrated on 15 August; that day is widely observed as the Feast of the Assumption, therefore he is not mentioned in the General Roman Calendar, but only in the Roman Martyrology.
