Heart

Heart symbolizes love and giving someone a heart means to hand over one's existence to someone. A heart pierced by a Cupid's arrow means that when someone presents a heart, the person takes the risk of being rejected and feeling hurt. Piercing arrow therefore symbolizes death and vulnerability of love. Some people also believe that the heart and arrow symbolizes the uniting of male and a female.

Cupid

Cupid, the playful winged angel, spreads love by piercing hearts with his golden arrows. It's no wonder that Cupid brings people together in love. In Roman mythology, he's the god of erotic love and the son of Venus, the goddess of love. In Greek mythology, he's known as Eros, the god responsible for love and lust. While Cupid had no connection with St. Valentine or the day itself, his reputation as a matchmaker made him a symbol of Valentine's Day.
