The Story of Alban and the Priest
In the received tradition, Amphibalus was a Roman Christian who fled persecution and took refuge in the house of Alban at Verulamium. Alban, then a pagan, was converted by the priest's example and instruction. When the authorities tracked the fugitive to Alban's dwelling, Alban put on the priest's garments and gave himself up in his place, and was arrested and executed — becoming the first recorded martyr of Britain.
Amphibalus is said to have escaped in the confusion. Some accounts associate him with Caerleon, where he was held to have converted numerous Britons — including figures named Socrates and Stephanus — before fleeing toward Wales. He was eventually seized by the Romans and brought back to Verulamium, where he was put to death. The manner of his execution is not consistently reported; sources variously describe beheading, stabbing, or stoning. By later tradition his martyrdom is placed at Redbourn, near St. Albans. According to Matthew Paris he was martyred at Verulamium following Alban's execution.
