Antonin de Césarée was a Christian priest who lived during the early 4th century. During the persecutions led by the Roman Emperor Galerius, he and several companions, including Zebinas, Germain, and Manathas, were arrested in Caesarea, Palestine. Their deaths occurred in 308 under the authority of the governor Firmilian. Antonin is remembered for his courageous refusal to allow the governor to perform sacrifices to pagan deities, an act of defiance that led to his immediate execution.
