Laurentius (possibly Caelius) was the Archpriest of Santa Prassede and later antipope of the See of Rome. Elected in 498 at the Basilica Saint Mariae (presumably Saint Maria Maggiore) with the support of a dissenting faction with Byzantine sympathies, who were supported by Eastern Roman Emperor Anastasius I Dicorus, in opposition to Pope Symmachus, the division between the two opposing factions split not only the church, but the Senate and the people of Rome. However, Laurentius remained in Rome as pope until 506.
