Saint Valentine doesn't occur in the earliest list of Roman martyrs, the "Chronography of 354", although the patron of the Chronography's compilation was a wealthy Roman Christian named Valentinus. However, it is found in the "Martyrologium Hieronymianum", which was compiled between 460 and 544 from earlier local sources. The feast of St. Valentine of February 14 was first established in 496 by Pope Gelasius I, who included Valentine among all those "... whose names are justly reverenced among men, but whose acts are known only to God."
