There are many opinons as to who was the original Valentine, with the most popular theory that it was a clergyman who was executed for secretly marrying couples in ancient Rome. In any event, in 496 A.D., Pope Gelasius set aside February 14 to honor St. Valentine. Through the centuries, the Christian holiday became a time to exchange love messages and St. Valentine became a patron saint of lovers. In the 1840s, Esther Howland, a native of Massachusetts, is given credit for sending the first Valentine cards. The spirit of love continues as valentines are sent with sentimental verses and children exchange valentine cards at school.
