Some trace Valentine’s Day origins to a Christian effort to replace a pagan fertility festival that has been dated as far back as the 6th century B.C.

4. What does wearing your heart on your sleeve really mean?

In the Middle Ages, young men and women drew names to see who their Valentine would be, the LA Times reports. According to Smithsonian, they would wear the name pinned to their sleeve for one week so that everyone would know their supposed true feelings. How cool is that?

5. Cupid Began as a Greek God

The chubby baby with wings and a bow and arrow that we call Cupid has been associated with Valentine’s Day for centuries. However, before he was renamed Cupid, he was known to the ancient Greeks as Eros, the god of love. Eros, the son of Greek goddess Aphrodite, would use two sets of arrows—one for love and another for hate—to play with the emotions of his targets. It wasn’t until stories of his mischief were told by Romans that he adopted the childlike appearance that we recognize today.

6. Did you know that candy hearts were originally medical lozenges?

In 1847, Boston pharmacist Oliver Chase invented a machine that simplified the lozenge production process, resulting in the first candy-making machine, according to The Oxford Encyclopedia of Food and Drink in America. After identifying an opportunity to revolutionize the candy business, Chase shifted his focus to candy production with Necco wafers.

7. Roses are the flowers of love.
