The origins of Valentine’s Day are murky. But it is thought to have been made a holiday in the fifth century when Pope Gelasius outlawed the celebration of Lupercalia. It wasn’t until much later that it became associated with romance. In the Middle Ages, it was believed that February 14 was the start of birds’ mating season. Chaucer cemented the connection between Valentine’s Day, birds and romance with his 1375 poem “Parliament of Foules,” writing, “For this was on Seynt Valentynes day, / Whan every foul cometh ther to chese his make.” The rest, as they say, is history!
