The Holy Martyrs Cyprian, Alphaeus, Philadelphus, Onesimus, Erasmus and 14 others with them, lived during the third century and came from Italy. Alphaeus, Philadelphus and Cyprian were sons of a governor in Italy, named Vitalius. They were enlightened by faith in Christ and baptized by St Onesimus.
The brothers Alphaeus, Philadelphus and Cyprian suffered in the city of Mesopolis Leontii in Sicily, where they had been sent from Rome. St Philadelphus was burned over an iron lattice in the year 251, in the reign of the emperor Decius.
In the year 1517 their incorrupt relics were discovered at Leontini [Lentini]. Sts Alphaeus, Philadelphus and Cyprian appeared to St Euthalia (March 2) and told her that she would be healed of an affliction after she was baptized.
