Black Tortoise

The Black Tortoise is one of the Four Symbols of the Chinese constellations. It is usually depicted as a tortoise entwined together with a snake. The name used in East Asian languages () does not mention either animal; the alternative English name Black Warrior is a more faithful translation. It represents the north and the winter season, thus it is sometimes called Black Warrior of the North (). In Japan, it is named Genbu. It is said to protect Kyoto on the north side, being one of the four guardian spirits that protect the city. It is represented by the Kenkun Shrine, which is located on top of Mt Funaoka in Kyoto. The creature's name is identical to that of the important Taoist god Xuanwu, who is sometimes (as in Journey to the West) portrayed in the company of a turtle and a snake. During the Han dynasty, people often wore jade pendants that were in the shape of turtles. Originally, there was a legend that said that turtles could not mate with other turtles, only snakes. This is why the Black Tortoise is depicted with a snake on its back. The northern gates of Chinese palaces were often named after the Xuanwu. Most famously, the Incident at Xuanwu Gate, where Li Shimin killed his brothers Jiancheng and Yuanji and seized power in a coup, took place at the north gate of the Taiji Palace, in the north of Chang'an. In ancient China, the tortoise and the serpent were thought to be spiritual creatures symbolizing longevity. The Min people custom of building turtle-shaped tombs may have had to do with the desire to place the grave under the influence of the Black Tortoise. Xuanwu (god) Chinese alchemy In the classic novel Journey to the West, Xuanwu was a king of the north who had two generals serving under him, a "Tortoise General" and a "Snake General". This god had a temple in the Wudang Mountains of Hubei and there are now a "Tortoise Mountain" and a "Snake Mountain" on opposite sides of a river near Wuhan, Hubei's capital. Taoist legend has it that Xuanwu was the prince of a Chinese ruler but was not interested in taking the throne, opting instead to leave his parents at age 16 and study Taoism.
