High Quality Content by WIKIPEDIA articles! Saint Hippolytus is usually understood to mean Hippolytus of Rome, a Roman priest celebrated in a common feast with Pope Pontian on 13 August as having both won the martyr's crown after being exiled to Sardinia after a period in which the priest had opposed the pope. Most, if not all, of what appear to be other martyrs of the same name seem to be in reality this same Hippolytus. The feast of Saint Hippolytus formerly celebrated on 22 August (see General Roman Calendar as in 1954) was a duplicate of the 13 August feast and for that reason was deleted when the Roman Catholic calendar of saints was revised in 1960.
