Cupid, another symbol of Valentines Day, became associated with it because he was the son of Venus, the Roman god of love and beauty. Cupid often appears on Valentine cards holding a bow and arrows because he is believed to use magical arrows to inspire feelings of love.
In the United States, 64 percent of men do not make plans in advance for a romantic Valentine's Day with their sweethearts. (HOW RUDE! LOL)
In Victorian times it was considered bad luck to sign a Valentine's Day card. (I wonder why? maybe it was supposed to stay a secret who it was from?)
It wasn't until 1537 that St. Valentine's Day was declared an official holiday. England's King Henry VIII declared February 14th a holiday
Some people used to believe that if a woman saw a robin flying overhead on Valentine's Day, it meant she would marry a sailor. If she saw a sparrow, she would marry a poor man and be very happy. If she saw a goldfinch, she would marry a millionaire. (I don't think I knew what any of those birds looked liked lol!)
The heart is the most common symbol of romantic love. Ancient cultures believed the human soul lived in the heart. Others thought it to be the source of emotion and intelligence. Some believed the heart embodied a man's truth, strength and nobility. The heart may be associated with love because the ancient Greeks believed it was the target of Eros, known as Cupid to the Romans. Anyone shot in the heart by one of Cupid's arrows would fall hopelessly in love. Because the heart is so closely linked to love, it's red colour is thought to be the most romantic.
