Saints Julian and Basilissa (died ca. 304) were husband and wife. They were Christian martyrs who died at either Antioch or, more probably, at Antinoe, in the reign of Diocletian, early in the fourth century, on 9 January, according to the Roman Martyrology, or 8 January, according to the Greek Menaea.
Their feast day is also given as 6 January, while a group of people martyred with Julian (Celsus, Marcionilla, Anthony, Anastasius) have the feast day of January 9.
Forced by his family to marry, Julian agreed with his spouse, Basilissa, that they should both preserve their virginity, and further encouraged her to found a convent for women, of which she became the superior, while he himself gathered a large number of monks and undertook their direction. The two converted their home into a hospital which could house up to 1,000 people (thus, Julian is often confused with Julian the Hospitaller).
Basilissa died a very holy death, but martyrdom was reserved for Julian under the persecutions of Diocletian.
Celsus, the young son of Marcionilla, was martyred along with Julian. The priest Anthony (Antony) was martyred at the same time, as well as a convert and neophyte named Anastasius. Marcionilla's seven brothers are also said to have been killed.
