After reviewing the definitions listed above, we can conclude that the word ouroboros refers to a coveted symbol that features either a snake, serpent, or dragon consuming its own tail, thereby forming a circle.

What Is the Origin of Ouroboros?

Also known as the “paradoxical serpent,” the ouroboros is the most ancient symbol of alchemy and represents the circular process of the alchemist’s work. That said, where did it come from?

Our word of the day derives from two ancient Greek terms: “oura” and “boros.” In short, “oura” refers to tail while “boros” means eating. So, when we combine these two words, it results in the meaning “tail-devourer” or “tail eater.”

While ouroboros isn’t attested in English until sometime around the 1940s, the concept is very ancient and has been used across a number of cultures as a symbol of cosmic harmony, eternity, and the cycle of birth and death.

Although the history is a bit blurry, the earliest record of the ouroboros symbol comes from a religious text that was found in King Tut’s (Tutankhamen) tomb in Ancient Egypt in the 13th century BC. The famous symbol appears in a passage about the origin of the sun god Ra through a union with the death god Osiris.

In the 2nd century BCE, the ouroboros was adopted by Gnostic philosophers and symbolized the dual nature of existence, marked by life and death, light and dark, male and female, earth and heaven, or mortality and divinity.

Fast forward to the 20th century when psychotherapist Carl Jung viewed the ouroboros as a symbol of the human psyche. Jung claimed that the symbol represented the human ability to regenerate through self-reflection — just as a serpent sheds off old skin to become anew.

What Does the Ouroboros Symbolize?

Seeing as the ouroboros symbol is one of the oldest ancient Egyptian symbols in history, it’s no surprise that it has a number of meanings that come from a number of different cultures.

To the Ancient Romans, the ouroboros symbolized infinity. They also associated it with the god Saturn who controlled the cycles of each year.

The ancient Aztecs portrayed their god — Quetzalcoatl — as a serpent biting his own tail, as seen in the ancient ruins such as the Pyramid of the Feathered Serpent.
