In Rome, the feast appears in the "Gelasian Sacramentary", a manuscript collection of the seventh and eighth centuries associated with Pope Gelasius I. There it carries for the first time the new title of the feast of Purification of the Blessed Virgin Mary. Late in time though it may be, Candlemas is still the most ancient of all the festivals in honor of the Virgin Mary. The date of the feast in Rome was 2 February because the Roman date for Christ's nativity had been 25 December since at least the early fourth century.
