Fun facts for Valentine's Day 2011 - WBOC-TV 16, Delmarvas News Leader, FOX 21 -

Valentine's Day is traditionally a day in which people express their love to one another by presenting gifts, such as cards, candy, flowers and other symbols of love or affection.

Opinions differ as to who was the original Valentine but the most popular theory is that he was a clergyman who was executed for secretly marrying couples in ancient Rome. In A.D. 496, Pope Gelasius I declared Feb. 14 as Valentine Day. Through the centuries, the Christian holiday became a time to exchange love messages, and St. Valentine became the patron saint of lovers.

Esther Howland, a native of Massachusetts, is given credit for selling the first mass-produced valentine cards in the 1840s. The spirit of love continues today with even young children exchanging valentine's cards with their fellow classmates.
