PRIEST AND MARTYR
Roman Martyrology: At Rome, on the Via Flaminia, near the Milvian Bridge, Saint Valentine, a martyr.
Valentine was a holy priest in Rome, who, with St. Marius and his family, assisted the martyrs in the persecution under Claudius II.
He was apprehended, and sent by the emperor to the prefect of Rome; who, on finding all his promises to make him renounce his faith ineffectual, commanded him to be beaten with clubs, and afterwards to be beheaded, which was executed on the 14th of February, about the year 270. Pope Julius I. is said to have built a church near Ponte Mole to his memory, which for a long time gave name to the gate, now called Ports del Popolo, formerly Porta Valentini. The greatest part of his relics are now in the church of St. Praxedes. His name is celebrated “as that of an illustrious martyr, in the sacramentary of St. Gregory, the Roman missal of Thomasius, in the calendar of F. Fronto, and that of Allatius, in Bede, Usuard, Ado, Notker, and all other martyrologies on this day.
To abolish the heathen's lewd superstitious custom of boys drawing the names of girls, in honor of their goddess Februata Juno, on the 15th of this month, several zealous pastors substituted the names of saints in billets given on this day.
