A serpent biting its own tail appears in Egyptian tomb paintings, Greek alchemical manuscripts, and Norse sagas. The name for that figure — Ouroboros — means “tail-devourer” in Greek, but the relationship between the symbol and the concept is not as simple as a label. The Ouroboros is the visual representation of the snake eating its own tail, but the concept of self-consuming cyclicality predates the name and exceeds it. The relationship is one of identity, but also of expansion: the symbol carries layers of meaning the bare concept does not.
The snake that eats its own tail is a paradox made visible. The Ouroboros captures that paradox and gives it a body, a name, and a history. We cannot separate them — the concept cannot be discussed without the image, but we can examine how the image came to represent the concept, and what the concept means across traditions.
Where the Tail-Devourer First Appears
The earliest known depiction of a snake eating its own tail is found in the tomb of Tutankhamun (c. 1323 BCE). The figure appears on the wooden shrine of the goddess Meretseger, a cobra-headed deity associated with the Theban necropolis. The serpent is painted in gold and blue, its body coiled into a circle with its head meeting its tail. No text from that tomb explains the meaning, but the context suggests protection and the cyclical nature of the sun’s journey through the underworld. The snake is not named “Ouroboros” there. That name comes later.
The first surviving use of the word “Ouroboros” is in the Greek alchemical text called the Chrysopoeia of Cleopatra (3rd century CE). The manuscript shows a single circle of black and white serpent, half light and half dark, with the Greek words “hen to pan” (one is the all) written inside. The alchemist Cleopatra (not the queen, but a female alchemist in Alexandria) used the Ouroboros to represent the unity of opposites and the completion of the Great Work. The snake eating its tail is the alchemical principle of solve et coagula made one: destruction and creation in a single gesture.
The Norse also had a version. Jörmungandr, the Midgard Serpent, encircles the world and bites its own tail. The Prose Edda (c. 1220 CE, by Snorri Sturluson) describes the serpent as lying in the ocean, surrounding the entire earth, holding its tail in its mouth. This is a cosmological Ouroboros: the boundary of the known world, the container of chaos.
The relationship between the symbol and the concept began, then, in multiple cultures at once. The concept of a self-consuming cycle, time, the sun, the alchemical opus, found a single image that could travel across borders.
What the Snake Eating Its Own Tail Actually Means
The concept of the snake eating its own tail is the most direct visual statement of non-linear time. A straight line has a beginning and an end. A circle has neither. The Ouroboros says: what consumes itself also renews itself. The tail is the end, but the mouth is the beginning. The venom that kills becomes the nourishment that sustains.
In alchemy, the Ouroboros represents the prima materia, the raw material from which all transformation begins. The alchemist must “eat” the material, dissolve it, reduce it to its first state, then allow it to reform. The snake is the operator and the operated. The Mutus Liber (1677), a wordless alchemical book, opens with an Ouroboros framing the entire work. The symbol tells the reader before a single image appears: this is a closed system, and the work is circular.
For the psychologist Carl Jung, the Ouroboros was an archetype of the self. In The Psychology of the Transference (1946), he wrote that the Ouroboros is “the basis of the process of individuation”, the stage where the psyche becomes aware of its own wholeness. The snake eating its own tail is the first awareness of the self as a closed loop, containing both light and shadow. Jung found the symbol in alchemical manuscripts and in his patients’ dreams, often drawn by people who had never seen the original images.
The concept also appears in Gnostic texts. In the Pistis Sophia (3rd–4th century CE), the Ouroboros is described as a serpent that surrounds the world, representing the boundary between the material realm and the divine. The Gnostics saw it as an image of the finite world consuming itself, a warning rather than a promise.
How the Ouroboros Is Used in Practice
The relationship between the snake and the concept becomes active when the symbol is used in ritual. The Ouroboros is not merely a picture to look at. It is a tool for thinking in circles.
In medieval alchemy, the Ouroboros was often drawn on the margins of recipes for the Philosopher’s Stone. The alchemist would trace the circle while reciting the formula “one is the all.” The gesture was a meditation on the unity of matter. The Ouroboros also appears on the cover of the Aurora Consurgens (c. 1400s), a text attributed to Thomas Aquinas but likely written by an anonymous alchemist. The serpent is painted in gold leaf, its body covered with scales that are each a different color, red, white, black, green, representing the stages of the Work.
Modern occult orders use the Ouroboros as a symbol of the closed current of magical energy. The Hermetic Order of the Golden Dawn placed the Ouroboros on the Stele of Revealing, the funerary stele of the priestess Ankh-ef-en-Khonsu (circa 680 BCE), which became central to Thelema. Aleister Crowley adopted the symbol for his own system, describing it as “the image of the cycle of existence” in The Book of Thoth (1944). The Ouroboros appears in the Thoth Tarot deck on the card of the Universe, framing the dancing figure.
In practical witchcraft, we have seen the Ouroboros drawn on a circle of salt to represent the boundary of the ritual space. The snake that eats its own tail is the circle that contains the energy until the work is done. The practitioner visualizes the serpent coiling around the circle, its mouth meeting its tail, sealing the boundaries. The concept of the closed loop becomes a physical barrier.
How the Ouroboros Differs from Other Eternal-Return Symbols
The snake eating its own tail is often confused with the infinity symbol (the lemniscate) or the wheel of fortune. The differences matter.
The lemniscate (∞) was introduced by the mathematician John Wallis in 1655 to represent infinity. It is a curve, not a living creature. The Ouroboros is biological: it eats, digests, and renews. The infinity symbol is static; the Ouroboros is active. The relationship between the concept of eternal return and the Ouroboros is closer, but the snake carries a dimension of mortality. The wheel of fortune is a cycle of rise and fall; the Ouroboros is a cycle of consumption and rebirth.
The Ouroboros also shares a shape with the Rim of the World in Hindu cosmology, where the serpent Shesha coils around the turtle Akupara, supporting the universe. But Shesha does not eat its own tail. It holds its tail in its mouth? In some depictions, Shesha is shown with his tail in his mouth, but the primary function is support, not self-consumption. The Ouroboros is specifically about the act of eating oneself.
Common Misconceptions About the Ouroboros
That it is exclusively a Greek symbol. The earliest Ouroboros is Egyptian, from the 14th century BCE. The Greek name came later, but the image is older.
That it is a symbol of destruction. The Ouroboros destroys only to renew. The alchemist reads it as a promise of transformation, not an end. The snake dies and is reborn each time it sheds its skin.
That it is the same as the serpent in the Garden of Eden. The biblical serpent is a tempter, not a self-consumer. The Ouroboros is not a character in a narrative. It is a symbol of a process.
That it is evil or satanic. Some Christian writers in the Middle Ages associated the Ouroboros with the devil because of the serpent’s role in Genesis. But the symbol was used in sacred Egyptian tombs and in Christian alchemical manuscripts. Its meaning depends on the context, not the shape.
FAQ
Is the Ouroboros the same as the infinity symbol?
No. The infinity symbol (lemniscate) is a mathematical curve. The Ouroboros is a serpent that eats its own tail, carrying meanings of life, death, and renewal that the infinity symbol does not.
What does the Ouroboros mean in alchemy?
It represents the unity of opposites, the cycle of solve et coagula (dissolve and coagulate), and the completion of the Great Work, the transformation of base matter into the Philosopher’s Stone.
Where did the Ouroboros originate?
The earliest known image is from the tomb of Tutankhamun (c. 1323 BCE). The word “Ouroboros” first appears in the Greek alchemical text Chrysopoeia of Cleopatra (3rd century CE).
How is the Ouroboros used in modern witchcraft?
Practitioners draw the Ouroboros as a boundary marker in ritual circles, visualize it to seal the sacred space, and meditate on the image to contemplate the cycle of life, death, and rebirth.
The Ouroboros is not a relic of a dead tradition. It is a living symbol that still asks us to think in circles, to see the end in the beginning and the beginning in the end. The snake that eats its own tail is the same concept, but the concept is incomplete without the image. The relationship is one of mutual dependence: the concept cannot be grasped without the snake, and the snake without the concept is just a drawing.
