Historically today is the feast of St. Juliana, a Christian virgin of Cumae, Italy, martyred for the faith when she refused to marry a Roman prefect. She suffered terrible ordeals and was finally beheaded. One tradition reports that Juliana actually suffered martyrdom at Nicomedia and that her relics were transferred to Cumae.
St. Juliana suffered martyrdom during the Diocletian persecution. Both the Latin and Greek Churches mention a holy martyr Juliana in their lists of saints. The oldest historical notice of her is found in the "Martryologium Hieronymianum" for 16 February, the place of birth being given as Cumae in Campania (In Campania Cumbas, natale Julianae). It is true that the notice is contained only in the one chief manuscript of the above-named martyrology (the Codex Epternacensis), but that this notice is certainly authentic is clear from a letter of St. Gregory the Great, which testifies to the special veneration of St. Juliana in the neighbourhood of Naples. A pious matron named Januaria built a church on one of her estates, for the consecration of which she desired relics (sanctuaria, that is to say, objects which had been brought into contact with the graves) of Sts. Severinus and Juliana. Gregory wrote to Fortunatus, Bishop of Naples, telling him to accede to the wishes of Januaria ("Gregorii Magni epist.", lib. IX, ep. xxxv, in Migne P.L., LXXXVII, 1015).
