Lung (Chinese: “dragon”) is, in Chinese mythology, a type of majestic beast that dwells in rivers, lakes, and oceans and roams the skies. Originally a rain divinity, the Chinese dragon, unlike its malevolent European counterpart, is associated with heavenly beneficence and fecundity. Rain rituals as early as the 6th century BC involved a dragon image animated by a procession of dancers; similar dances are still practiced in traditional Chinese communities to secure good fortune. Ancient Chinese cosmogonists defined four types of dragons: the Celestial Dragon, who guards the heavenly dwellings of the gods; the Dragon of Hidden Treasure; the Earth Dragon, who controls the waterways; and the Spiritual Dragon, who controls the rain and winds. In popular belief, only the latter two were significant; they were transformed into the Dragon Kings, gods who lived in the four oceans, delivered rain, and protected seafarers. Generally depicted as a four-legged animal with a scaled, snakelike body, horns, claws, and large, demonic eyes, the lung was considered the king of animals, and his image was appropriated by Chinese emperors as a sacred symbol of imperial power.
