Valentine was a 3rd century Roman priest who secretly conducted marriages against Emperor Claudius II's decree banning marriage for young people. When discovered, Valentine was imprisoned and sentenced to death. He is now the patron saint of lovers. February 14th is celebrated as Valentine's Day in many countries where couples exchange gifts, cards, flowers and chocolate to express love. While traditions and dates vary in some countries, red hearts and cupid are universal symbols of the commercialized holiday of love.
