Saint Valentine's Day, commonly shortened to Valentine's Day, is an annual commemoration held on February 14 celebrating love and affection between intimate companions. The day is named after one or more early Christian martyrs, Saint Valentine, and was established by Pope Gelasius I in 496 AD. It was deleted from the Roman calendar of saints in 1969 by Pope Paul VI, but its religious observance is still permitted. It is traditionally a day on which lovers express their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as "valentines"). The day first became associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished.
Modern Valentine's Day symbols include the heart-shaped outline, doves, and the figure of the winged Cupid. Since the 19th century, handwritten valentines have given way to mass-produced greeting cards.
Numerous early Christian martyrs were named Valentine. The Valentines honored on February 14 are:
- Valentine of Rome (Valentinus presb. m. Romae)
- Valentine of Terni (Valentinus ep. Interamnensis m. Romae).
Valentine of Rome was a priest in Rome who was martyred about AD 269 and was buried on the Via Flaminia. His relics are at the Church of Saint Praxed in Rome, and at Whitefriar Street Carmelite Church in Dublin, Ireland.
