Hippolytus was a priest and a learned man, the most important writer of the Church at Rome in the early third century. He strongly attacked the popes of the time, and was set up as a rival Pope to St Callistus. Some time later, in Maximin’s persecution, he was sent to labour in the quarries of Sardinia. There he met the then Pope, Pontian, and was reconciled with him.
Pontian was made Pope in 231, and was sent to the quarries in 235, where he resigned the papacy and died. Pontian’s successor, Fabian, had both bodies brought back to Rome for burial, and Pontian and Hippolytus were already being venerated by the Roman Church by the start of the fourth century.
