History

Depictions of mythological creatures clearly ancestral to the modern set of four creatures have been found throughout China. Currently, the oldest known depiction was found in 1987 in a tomb in Xishuipo (西水坡) in Puyang, Henan, which has been dated to approximately 5300 BC. In the tomb, labeled M45, immediately adjacent to the remains of the main occupant to the east and west were found mosaics made of clam shells and bones forming images closely resembling the Azure Dragon and White Tiger, respectively.

The modern standard configuration was settled much later, with variations appearing throughout Chinese history. For example, the Rongcheng Shi manuscript recovered in 1994, which dates to the Warring States Period (ca. 453–221 BCE), gives five directions rather than four and places the animals differently. According to that document, Yu the Great gave directional banners to his people, marked with the following insignia: the north with a bird, the south with a snake, the east with the sun, the west with the moon, and the center with a bear.

In Taoism, the Four Symbols have been assigned human identities and names. The Azure Dragon is named Meng Zhang (孟章), the Vermilion Bird is called Ling Guang (陵光), the White Tiger Jian Bing (監兵), and the Black Tortoise Zhi Ming (執明).

The colours associated with the four creatures can be said to match the colours of soil in the corresponding areas of China: the bluish-grey water-logged soils of the east, the reddish iron-rich soils of the south, the whitish saline soils of the western deserts, the black organic-rich soils of the north, and the yellow soils from the central loess platea
