In European folklore, a dragon is a serpentine legendary creature. The Latin word draco, as in constellation Draco, comes directly from Greek δράκων, (drákōn, gazer). The word for dragon in Germanic mythology and its descendants is worm (Old English: wyrm, Old High German: wurm, Old Norse: ormr), meaning snake or serpent. In Old English wyrm means “serpent”, draca means “dragon”. Finnish lohikäärme directly translated means “salmon-snake”, but the word lohi- was originally louhi- meaning crags or rocks, a “mountain snake”. The word lohi- in lohikäärme is also thought to derive from the ancient Norse word lógi, meaning ‘fire’ as in the Finnish mythology, there is also mentions of “tulikäärme” meaning firesnake, or fireserpent. Though a winged creature, the dragon is generally to be found in its underground lair, a cave that identifies it as an ancient creature of earth. Likely, the dragons of European and Mid Eastern mythology stem from the cult of snakes found in religions throughout the world.In Western folklore, dragons are usually portrayed as evil, with the exceptions mainly in Welsh folklore and modern fiction. In the modern period the dragon is typically depicted as a huge fire-breathing, scaly and horned dinosaur-like creature, with leathery wings, with four legs and a long muscular tail. It is sometimes shown with feathered wings, crests, fiery manes, ivory spikes running down its spine and various exotic colorations.Many modern stories represent dragons as extremely intelligent creatures who can talk, associated with (and sometimes in control of) powerful magic. Dragons have also been shown as guardians and friends of humans, with evil dragons simply misunderstood by humans. In stories a dragon’s blood often has magical properties: for example in the opera Siegfried it let Siegfried understand the language of the Forest Bird. The typical dragon protects a cavern or castle filled with gold and treasure and is often associated with a great hero who tries to slay it, but dragons can be written into a story in as many ways as a human character, including as wise beings whom heroes can approach for help and advice; in some such cases they resemble Asian rather than European dragons.
