Saint Boniface of Tarsus was a Christian martyr who was executed in the year 307 at Tarsus, where he had gone from Rome in order to bring back holy relics of the martyrs requested by his mistress Aglaida. Finding upon arrival at Tarsus that the authorities were torturing Christians, he openly declared himself to be a Christian. His own body constituted the relics that were brought back to Aglaida, who in turn also became a Christian. The Orthodox Church celebrates both of them on 19 December as the "Martyr Boniface at Tarsus in Cilicia and Righteous Aglaida of Rome".
