Boniface was a debauched, drunken fellow, a servant of Aglae, daughter of the pro-consul Acacius, who lived on terms of undue familiarity with his mistress, in the reigns of Diocletian and Maximus. But one day, at Tarsus, he saw some Christian martyrs hung up over a slow fire by their hands tied behind their backs; others with their flesh torn off by scrapers; others with their hands cut off. The sight of their constancy and faith so overpowered him, that he ran up to them and besought them to pray for him, for he was a miserable sinner. Then feeling the pricking of his conscience, and an earnest resolve to submit to any torment to redeem the past, he delivered himself up to the governor, and declared himself to be a Christian. He was tortured in the most excruciating manner, and was then decapitated when more dead than alive, and so received the baptism of blood.
