The Eight Pillars also known as Eight Pillars of the Sky are a concept from Chinese mythology. Located in the eight cardinal directions, they are a group of eight mountains or pillars which have been thought to hold up the sky. They are symbolically important as types of axis mundi and cosmology. Their functions in mythology ranged from pillars which functioned to hold apart the Earth and the Sky (or Heaven), as ladders allowing travel between the two, and as the location of various paradises or wonderland with associated magical people, plants, and animals. The Eight Pillars are a central aspect to Chinese mythology, and also have been used extensively in poetic allusion. Some variations exist, such as only having four pillars.
