Cupid is the god of desire, erotic love, attraction and affection. He is often portrayed as the son of the love goddess Venus and the war god Mars.
Cupid is also known in Latin also as Amor ("Love"). His Greek counterpart is Eros and he is just one of the ancient symbols associated with St Valentine's Day, along with the shape of a heart, doves, and the colours red and pink.
He is usually portrayed as a small winged figure with a bow and arrow which he uses to strike the hearts of people. People who fall in love are said to be 'struck by Cupid's arrow'.
