A dragon is a fire-breathing mythological animal, a winged, flying, scaly creature. In many European legends, brave knights battle evil dragons.
The dragon shows up in the mythologies of many different cultures, usually breathing fire and resembling a giant reptile or serpent with wings. The monster in the ancient Mesopotamian poem the "Epic of Gilgamesh" is often called a dragon, and the Old English story "Beowulf" also features a fearsome dragon. In several Asian cultures, dragons represent wisdom, nature, and longevity. The Greek root is drakon, "serpent" or "giant seafish."
