Very little historical information about Saint Hippolytus has been preserved. It is fragmentary and piecemeal in nature, and the data about him, recorded in the works of different authors, largely contradict each other, making it impossible to accurately identify his personality or compile a complete and reliable list of his writings. According to the most common hypothesis, Hippolytus was the leader of a rigorist faction within the Roman Church who opposed Hieromartyr Callistus, Pope of Rome, and created an alternative community in Rome, which persisted during the two subsequent pontificates. Nevertheless, the current state of historiography on this problem indicates that its solution is impossible through any particular combination of the available sources. It is possible that in the 6th century, the identity of this saint was conflated with Hieromartyr Hippolytus, who was buried on the Via Tiburtina.
