As well as St John of the Cross, today is also the memorial of St Chrysogonus, who was martyred under Diocletian at Aquileia. A titular church in Rome, probably dating originally from the fourth century, at Trastevere, bears his name.
According to his legend (from the Catholic Encyclopedia), Chrysogonus was a functionary of the vicarius Urbis, and was the Christian teacher of Anastasia, the daughter of the noble Roman Praetextatus. Being thrown into prison during the persecution of Diocletian, he comforted by his letters the severely afflicted Anastasia. By order of Diocletian, Chrysogonus was brought before the emperor at Aquileia, condemned to death, and beheaded. His corpse, thrown into the sea, was washed ashore and buried by the aged priest, Zoilus.
