Human uses of reptiles have for centuries included both symbolic and practical interactions. Symbolic uses of reptiles include accounts in mythology, religion, and folklore as well as pictorial symbols such as medicine's serpent-entwined caduceus. Myths of creatures with snake-like or reptilian attributes are found around the world, from Chinese and European dragons to the Woolunga of Australia. Classical myths told of the nine-headed Lernaean Hydra, the Gorgon sisters including the snake-haired Medusa, and the snake-legged Titans. Crocodiles appear in the religions of Ancient Egypt, in Hinduism, and in Aztec and other Latin American cultures.
