Broad history from Baoning Temple in
Shanxi,
China. Dragons of the Five Regions/Directions existed in Chinese custom, established by the
Former Han period(200BCE) (Cf.
§Origins below). The same concept couched in "dragon king" (
longwang) terminology from "dragon" was centuries later, the term "dragon king" being imported from India (
Sanskrit naga-raja), And the
Luxuriant Dew of the Spring and Autumn Annals attributed to
Dong Zhongshu (2nd cent. BC) describes the ritual involving five colored dragons.
Attestations of Five Dragon Kings Consecration Sutra The
apocryphal (early 4th century, attributed to
Po-Srimitra ), which purports to be Buddhist teachings but in fact incorporates elements of Chinese traditional belief, associates five dragon kings with five colored dragons with five directions, as aforementioned. The text gives the personal names of the kings. To the east is the Blue Dragon Spirit King () named , with 49 dragon kings under him, with 70
myriad myllion lesser dragons, mountain spirits, and assorted demons as minions. The thrust of this scripture is that in everywhere in every direction, there are the minions causing poisonings and ailments, and their lord the dragon kings must be beseeched in prayer to bring relief. In the south is the Red Dragon Spirit King named , in the west the White, called , in the north the Black, called and at center the Yellow, called , with different numbers subordinate dragon kings, with minion hordes of lesser dragons and other beings. Though connection of poison to rainmaking may not be obvious, it has been suggested that this poison-banishing sutra could have viably been read as a replacement in the execution of the ritual to pray for rain (, ), in Japan. A medieval commentary (, copied 1310) has reasoned that since the Great Peacock (
Mahāmāyūrī) sūtra mandates one to chant dragon names in order to detoxify, so shall
offerings made to dragon lead to "sweet rain".
Divine Incantations Scripture The ("five position") dragon kings are also attested in the , though not explicitly under the collective name of "five position dragon kings", but individually as "Eastern Direction's Blue Emperor Blue Dragon King ()", and so forth. It gives a laundry list of dragon kings by different names, stating that spells to cause rain can be performed by invoking dragon kings.
Ritual process An ancient procedural instruction for invoking five-colored dragons to conduct
rainmaking rites occurs in the
Luxuriant Dew of the Spring and Autumn Annals, under its "Seeking Rain" chapter (originally 2nd century B.C.). It prescribes earthenware figurines of greater and lesser dragons of a specific color according to season, namely blue-green, red, yellow, white, black, depending on whether it was spring, summer, late summer (), autumn, or winter. And these figures were to be placed upon the alter at the assigned position/direction (east, south, center, west, or north). This Chinese folk rain ritual later became incorporated into
Daoism. The rituals were codified into Daoist scripture or Buddhist sūtras in the post-
Later Han () period, but Dragon King worship did not come into ascendancy until the Sui-Tang dynasties. The
rain rituals in
Esoteric Buddhism in the Tang dynasty was actually an adaptation of indigenous Chinese dragon worship and rainmaking beliefs, rather than pure Buddhism. As a point of illustration, a comparison can be made against Buddhist procedures for rainmaking during the Tang dynasty. The rainmaking tract in Atikūṭa 's translated , (Book 11, under the chapter for ) prescribes an altar to be built, with mud figures of dragon kings placed on the four sides, and numerous mud-made lesser dragons arranged within and without the altar. ==Dragon Kings of the Four Seas==
