Christian feast day: Alphius, Philadelphus and Cyrinus

Saints Alphius, Philadelphus and Cyrinus, martyrs in the Byzantine traditions of southern Italy, were three brothers from Vaste, in the diocese of Otranto, who died with their mother, Benedicta, during the persecution of Decius, ca 251 AD. The details concerning these martyrdoms are traditional, drawn up at a later date in the Benedictine Acta of Saint Alphius.
