Reigned in 308 to 309. Born Rome; died in exile. After an interregnum of two years Marcellus became pope and undertook the ecclesiastical reorganization of Rome. He incurred the enmity of the Lapsi who wished to be pardoned without doing the penance prescribed for their apostasy. Serious conflicts ensued, and the tyrant Maxentius seized the pope and sent him into exile, where he died. Feast, Roman Calendar, 16 January.
