Saint Fabius was a Christian martyr living in the Roman province of Mauretania Caesariensis during the late third century. He is remembered for his refusal to serve as a standard-bearer for a local governor, as the ceremony involved pagan symbols that conflicted with his faith. Following his refusal, he was imprisoned and subjected to torture, but he remained steadfast in his convictions. He eventually met his death by decapitation in Cherchell around 303 or 304.
