Neidan Illustration of Bringing Together the Four Symbols和合四象圖, 1615 Xingming guizhi
The Four Symbols are mythological creatures appearing among the Chinese constellations along the ecliptic, and viewed as the guardians of the four cardinal directions. These four creatures are also referred to by a variety of other names, including "Four Guardians", "Four Gods", and "Four Auspicious Beasts". They are the Azure Dragon of the East, the Vermilion Bird of the South, the White Tiger of the West, and the Black Tortoise (also called "Black Warrior") of the North. Each of the creatures is most closely associated with a cardinal direction and a color, but also additionally represents other aspects, including a season of the year, an emotion, virtue, and one of the Chinese "five elements" (wood, fire, earth, metal, and water). Each has been given its own individual traits, origin story and a reason for being. Symbolically, and as part of spiritual and religious belief and meaning, these creatures have been culturally important across countries in the Sinosphere.
