In the 14th century, where the French love tradition flourished, it became the romantic love in the circle of Geoffrey Chaucer. In the 18th century England, it developed into a situation where lovers express each other's love by showing flowers, offering candy and sending greeting cards (known as "Valentine's Day"). In Europe, the keys to the Christmas Valentine's Day are given to lovers "as a romantic sign and invitation to release the heart of the giver" as well as children to prevent epilepsy (known as St. Valentine's Nausea). Today's Valentine's Day symbols include heart-shaped silhouettes, pigeons and winged Cupid images. Since the 19th century, hand-written Valentine's Day has given way to popular greeting cards.
Saint Valentine's Day is an official feast day in the Anglican Communion, as well as in the Lutheran Church. Many parts of the Eastern Orthodox Church also celebrate Saint Valentine's Day, albeit on July 6 and July 30, the former date in honor of the Roman presbyter Saint Valentine, and the latter date in honor of Hieromartyr Valentine, the Bishop of Interamna (modern Terni).
