Hippolytus's principal work is his Refutation of all Heresies (largely discovered only in the 19th cent.), whose object was to show that all heresies derived from pagan philosophy. Historically more important is his treatise The Apostolic Tradition; this was composed c.215, and contains detailed descriptions of the rites of ordination, baptism, and the eucharist as practised at the time in Rome. Feast day, 13 Aug. (W.), 30 Jan. (E.).
