"At Aphrodisia, in Caria, the holy martyrs Diodorus and Rodopian, who were stoned to death by their fellow-citizens, in the persecution of Diocletian."[4]
Tradition relates that, after a lengthy imprisonment, Pope Saint Alexander I and two priests, Eventius and Theodulus, were burned and then beheaded during Hadrian's persecution. During his imprisonment, Alexander is said to have brought Saint Quirinus and his daughter Saint Balbina to the faith. Today's saints were buried on the Via Nomentana near Rome. Their relics were later translated to the church of Saint Sabina, which now belongs to the Dominicans. Although called Pope Alexander in the Roman Martyrology, all sources agree that this is probably an erroneous listing (Benedictines, Coulson, Delaney, Husenbeth).[14] (The identification of the martyr Alexander with the Pope was removed from the Roman Calendar by Pope John XXIII in 1960.)
