The two most familiar interpretations of dragons are either European dragons, derived from various European folk traditions, or unrelated Oriental dragons, derived from the Chinese dragon (lóng,龍,龙). The word "dragon" derives from Greek δράκων (drakōn), "a serpent of huge size, a python, a dragon" and that from δρακεῖν (drakein) aorist infinitive active of the verb δέρκομαι (derkomai) "I see clearly".

Description

Dragons are usually shown in modern times with a body like a big lizard, or a snake with two pairs of lizard-type legs, and able to emit fire from its mouth. The European dragon has bat-type wings growing from its back. A dragon-like animal with no front legs and walking only on its back legs is a wyvern. Following discovery of how pterosaurs walked on the ground, some dragons have been drawn using the wings as front legs pterosaur-fashion when on the ground, as in this image and in the movie Reign of Fire.

Overview

Like most mythological creatures, dragons are perceived in different ways by different cultures. Dragons are sometimes said to breathe and spit fire or poison. They are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing typically feathered or scaly bodies. They are sometimes portrayed as having large yellow or red eyes, a feature that is the origin for the word for dragon in many cultures. They are sometimes portrayed with a row of dorsal spines, keeled scales, or leathery bat-like wings. Winged dragons are usually portrayed only in European dragons while Oriental versions of the dragon resemble large snakes. Dragons can have a variable number of legs: none, two, four, or more when it comes to early European literature. Modern depictions of dragons tend to be larger than their original representations, which were often smaller than humans.

Although dragons occur in many legends around the world, different cultures have varying stories about monsters that have been grouped together under the dragon label.

Dragons are often held to have major spiritual significance in various religions and cultures around the world. In many Asian cultures dragons were, and in some cultures still are, revered as representative of the primal forces of nature, religion and the universe. They are associated with wisdom—often said to be wiser than humans—and longevity. They are commonly said to possess some form of magic or other supernatural power, and are often associated with wells, rain, and rivers. In some cultures, they are also said to be capable of human speech.

The term dragoon, for infantry that move around by horse yet still fight as foot soldiers, is derived from their early firearm, the "dragon", a wide-bore musket that spat flame when it fired, and was thus named for the mythical creature.
