The serpent, when forming a ring with its tail in its mouth, is a clear and widespread symbol of the "All-in-All", the totality of existence, infinity and the cyclic nature of the cosmos. The most well known version of this is the Aegypto-Greek Ourobouros. It is believed to have been inspired by the Milky Way, as some ancient texts refer to a serpent of light residing in the heavens.

In Hindu mythology Lord Vishnu is said to sleep while floating on the cosmic waters on the serpent Shesha. In the Puranas Shesha holds all the planets of the universe on his hoods and constantly sings the glories of Vishnu from all his mouths. He is sometimes referred to as "Ananta-Shesha," which means "Endless Shesha". In the Samudra manthan chapter of the Puranas, Shesha loosens Mount Mandara for it to be used as a churning rod by the Asuras and Devas to churn the ocean of milk in the heavens in order to make Soma (or Amrita), the divine elixir of immortality. As a churning rope another giant serpent called Vasuki is used.

In pre-Columbian Central America Quetzalcoatl was sometimes depicted as biting its own tail. The mother of Quetzalcoatl was the Aztec goddess Coatlicue ("the one with the skirt of serpents"), also known as Cihuacoatl ("The Lady of the serpent"). Quetzalcoatl's father was Mixcoatl ("Cloud Serpent"). He was identified with the Milky Way, the stars and the heavens in several Mesoamerican cultures.
