Caesarius of Africa was a Christian deacon and hieromartyr who lived during the era of the Roman emperor Trajan. Originally from North Africa, he arrived in the Italian coastal town of Terracina following a shipwreck. There, he gained notoriety for denouncing a local pagan ritual involving human sacrifice dedicated to Apollo. His refusal to participate in these ceremonies led to his arrest and eventual execution, making him a significant figure in the early history of the Church in Italy.
