Around 1 billion Valentine's Day cards are exchanged each year, making it the second largest seasonal card-sending occasion after Christmas. In ancient Rome, Emperor Claudius II had a priest named Valentine executed for secretly performing marriages, and in the Middle Ages, young men and women would draw names from a bowl to see who their valentines would be for the week. Various old traditions and superstitions surrounding Valentine's Day include beliefs about what type of bird a woman saw predicting her future husband, eating a hard-boiled egg on Valentine's Eve would reveal one's future spouse in a dream, and the city of Verona receives about 1,000 letters annually addressed to Shakespeare's Juliet.
