The World Turtle (also referred to as the Cosmic Turtle, the World-bearing Turtle, or the Divine Turtle) is a mytheme of a giant turtle (or tortoise) supporting or containing the world. The mytheme, which is similar to that of the World Elephant and World Serpent, occurs in Chinese mythology and the mythologies of the indigenous peoples of the Americas. The "World-Tortoise" mytheme was discussed comparatively by Edward Burnett Tylor (1878:341).
The World Turtle in Hindu mythology is known as Akupāra (Sanskrit: अकूपार), or sometimes Chukwa. Example of a reference to the World Turtle in Hindu literature is found in Jñānarāja (the author of Siddhāntasundara, writing c. 1500): "A vulture, which has only little strength, rests in the sky holding a snake in its beak for a prahara [three hours]. Why can [the deity] in the form of a tortoise, who possesses an inconceivable potency, not hold the Earth in the sky for a kalpa [billions of years]?" The British philosopher John Locke made reference to this in his 1689 tract, An Essay Concerning Human Understanding, which compares one who would say that properties inhere in "substance" to the Indian, who said the world was on an elephant, which was on a tortoise, "but being again pressed to know what gave support to the broad-backed tortoise, replied—something, he knew not what."
Brewer's Dictionary of Phrase and Fable lists, without citation, Maha-pudma and Chukwa as names from a "popular rendition of a Hindu myth in which the tortoise Chukwa supports the elephant Maha-pudma, which in turn supports the world".
In Chinese mythology, the creator goddess Nüwa cut the legs off the giant sea turtle Ao (Chinese: 鳌; pinyin: áo) and used them to prop up the sky after Gong Gong damaged Mount Buzhou, which had previously supported the heavens.
