“On February 14, Americans celebrate love and friendship by exchanging cards, flowers, and candy. Although the origins of Valentine’s Day are murky, ancient Romans celebrated the feast of Lupercalia, a spring festival, on the fifteenth of February. Like so many holidays, a Christian gloss was added to the pagan fete when the holiday moved to the fourteenth of February—the saint day associated with several early Christian martyrs named Valentine.
“The romance we associate with Valentine’s Day may spring from the medieval belief that birds select their mates on February 14. During the Middle Ages, lovers recited verse or prose to one another in honor of the day. The Nuremberg Chronicle (published in 1493) is believed to contain the first in-print mention of Saint Valentine, though his role as patron saint of lovers was not mentioned.”
