Something wrong?He held the papacy for less than nine months in 336, yet Pope Mark may have launched two of the early Church's most enduring record-keeping traditions and secured Ostia's bishop as the consecrator of future popes.

About this person
Mark was a Roman, son of Priscus, who succeeded Sylvester I on 18 January 336. Evidence suggests the Depositio episcoporum and Depositio martyrum - early lists of bishops and martyrs - were begun under his watch. He issued a constitution giving the bishop of Ostia the pallium and the authority to consecrate newly elected popes, formalizing a ritual that would last centuries. He founded the Basilica of San Marco in Rome and a cemetery church over the Catacomb of Balbina on land donated by Constantine. Mark died of natural causes on 7 October 336, just under nine months into his papacy, and was buried in the catacomb of Balbina. His remains were moved to Velletri in 1048, then to the Basilica of San Marco in 1145, where they rest in an urn beneath the altar.
