Saint Valentine’s Day, often simply Valentine’s Day, is a holiday observed on February 14 honoring one or more early Christian martyrs named Valentinus. It was first established by Pope Gelasius I in 496 AD, and was later deleted from the General Roman Calendar of saints in 1969 by Pope Paul VI. It is celebrated in countries around the world, mostly in the West, although it remains a working day in all of them.
According to that version, St Valentine was persecuted as a Christian and interrogated by Roman Emperor Claudius II in person. Claudius was impressed by Valentine and had a discussion with him, attempting to get him to convert to Roman paganism in order to save his life. Valentine refused and tried to convert Claudius to Christianity instead. Because of this, he was executed. Before his execution, he is reported to have performed a miracle by healing the blind daughter of his jailer.
Lore has been embroidered in modern times to portray Valentine as a priest who refused an unattested law attributed to Roman Emperor Claudius II, allegedly ordering that young men remain single. The Emperor supposedly did this to grow his army, believing that married men did not make for good soldiers. The priest Valentine, however, secretly performed marriage ceremonies for young men. When Claudius found out about this, he had Valentine arrested and thrown in jail.
In 1797, a British publisher issued The Young Man’s Valentine Writer, which contained scores of suggested sentimental verses for the young lover unable to compose his own. Printers had already begun producing a limited number of cards with verses and sketches, called “mechanical valentines,” and a reduction in postal rates in the next century ushered in the less personal but easier practice of mailing Valentines. That, in turn, made it possible for the first time to exchange cards anonymously, which is taken as the reason for the sudden appearance of racy verse in an era otherwise prudishly Victorian.
Paper Valentines became so popular in England in the early 19th century that they were assembled in factories. Fancy Valentines were made with real lace and ribbons, with paper lace introduced in the mid-19th century.
