Many myths surround the origin of Valentine's Day.

At the Roman festival of Lupercalia, on Feb. 14, young couples were brought together by drawing names at random from an urn.According to researchers at Hallmark Cards, tradition says a Christian martyr named St. Valentine, imprisoned in Rome in A.D. 269, restored the sight of his jailer's blind young daughter. On his execution day, Feb. 14, he supposedly sent the girl a farewell note signed, "From Your Valentine."

In 1415, an early valentine was sent by Charles, Duke of Orleans, to his wife while he was a prisoner in the Tower of London. Commercial valentines were introduced in Europe in the early 1800s.
