Pamphilus of Caesarea was a prominent priest and biblical scholar who lived during the late third and early fourth centuries. Born into a wealthy family in Beirut, he studied in Alexandria under Pierius before moving to Caesarea Maritima. He is widely recognized for his scholarly dedication, serving as a mentor to Eusebius of Caesarea. During the Diocletianic persecution, he was imprisoned, where he continued his literary work. He eventually faced martyrdom in 309 when he refused to participate in pagan sacrifices.
