Lions are a popular animal depicted in cameos, intaglios and other art. They are often associated with strength and royalty. They also have a place in mythology such as the winged lion, a mythological creature that resembles a lion with bird-like wings, and the Nemean lion, a vicious monster in Greek mythology that lived at Nemea. It was eventually killed by Heracles. It could not be killed with mortals’ weapons because its golden fur was impervious to attack. Its claws were sharper than mortals’ swords and could cut through any armour. Reference: Wikipedia.
