To understand the Eye of Horus, one must first understand the god Horus himself. Horus stands as one of the most ancient, significant, and widely worshipped deities in the vast Egyptian pantheon. His origins stretch back into the Predynastic period (before c. 3100 BCE), making his worship older than the unified Egyptian state itself. Primarily known as a sky god, Horus was inextricably linked with kingship, the living pharaoh being considered his earthly embodiment. At various times and in different contexts, he also incorporated aspects of a sun god.
His primary cult center was the city of Nekhen, known by its Greek name Hierakonpolis, meaning “City of the Hawk” or “City of the Falcon.” Fittingly, this city served as the capital of Upper Egypt during the formative stages of Egyptian civilization. Horus himself was most commonly depicted as a majestic falcon or as a man with the head of a falcon. His Egyptian name, often rendered as Hrw or Heru, is thought to mean “Falcon,” but could also signify “He Who Is Above” or “He Who Is Distant,” evoking his dominion over the heavens.
The mythology surrounding Horus is notably complex, featuring multiple forms and stories that developed over Egypt’s long history. One early tradition identifies “Horus the Elder” (Heru-ur) as one of the original five children of Geb (earth god) and Nut (sky goddess), making him the brother of Osiris, Isis, Set, and Nephthys.
However, the most famous and enduring myth casts Horus as the son of the divine couple Osiris and Isis. In this narrative, Horus is conceived posthumously after his father Osiris, the rightful king, is murdered and dismembered by his jealous brother, Set. Isis magically reassembles Osiris and conceives Horus, whom she raises in secret to protect him from Set. Upon reaching adulthood, Horus avenges his father and battles Set for the throne of Egypt, a struggle known as the “Contendings of Horus and Set.”
Later, during the Hellenistic and Roman periods (after 332 BCE), Horus was assimilated into Greco-Roman culture as Harpocrates (Heru-pa-khered, “Horus the Child”), often depicted as a young boy with his finger to his lips, a gesture misinterpreted by Greeks as silence but likely representing childhood.
Furthermore, Horus was frequently syncretized with the principal sun god Ra, particularly during the New Kingdom. This fusion created the deity Ra-Horakhty (“Ra-Horus of the Two Horizons”). Depictions of Ra-Horakhty typically show a falcon-headed man crowned with a large sun disk, encircled by a protective cobra (the uraeus). This blending highlights the fluid nature of Egyptian deities and the tendency to merge attributes and identities, linking Horus’s kingship aspect directly with the supreme power of the sun.
The Myth and Ritual of the Eye
The Eye of Horus, or Wadjet eye, is deeply embedded in the core mythology of Horus, particularly his conflict with Set. As the divine prototype of the pharaoh, Horus embodied kingship, and the symbols associated with him carried immense weight regarding royal power, legitimacy, and divine protection. The Eye was one of the most prominent of these symbols.
According to the central myth, during one of the fierce battles in the Contendings of Horus and Set, Set managed to injure Horus, gouging out his left eye. This left eye was often symbolically associated with the moon, just as his right eye was linked to the sun. The loss of the eye represented a disruption of cosmic order and a temporary victory for the forces of chaos embodied by Set.
However, the eye was not lost forever. In most versions of the myth, the eye was magically restored, healed, or found by another deity, typically Thoth, the god of wisdom, writing, and magic. Thoth’s act of restoration symbolized healing, wholeness, and the triumph of order (Ma’at) over chaos (Isfet). Horus then offered the restored eye to his deceased father, Osiris, in an act that helped to revive him and grant him power in the underworld.
This mythic act of restoration resonated deeply within Egyptian funerary beliefs, particularly concerning the pharaoh. The ancient Pyramid Texts, inscribed inside pyramids during the Old Kingdom (c. 2700-2200 BCE), are replete with references to the Eye of Horus. These texts, among the oldest religious writings in the world, contain spells and hymns intended to ensure the king’s successful transition into the afterlife. The Eye of Horus features prominently as an icon of protection, offering, and resurrection, mirroring the restoration of Horus’s own eye and the revival of Osiris.
In the pyramid of Unas, the last king of the 5th Dynasty (c. 2375-2345 BCE), the hymns repeatedly invoke the Eye:
It is presented as a powerful, rejuvenating ointment: “Osiris Unas, I give you the Eye of Horus, that your face may be adorned with it, that the perfume of the Eye of Horus may spread towards you…”
The hymns directly reference the conflict with Set: “Osiris Unas, take the Eye of Horus snatched from Seth, which you shall take to your mouth, that you open your mouth with it!” This suggests the eye grants the power of speech or sustenance in the afterlife.
The Eye also represents the essential offerings provided for the deceased king’s eternal sustenance: “Unas, take the Eye of Horus which you shall find! … Unas, take the Eye of Horus, the liquid which came out of Osiris! Unas, take the Eye of Horus which was rescued for you, which will not separate itself from you! Unas, take the Eye of Horus that you may be provided with it!” The offerings listed often included essentials like meat, wine, and beer, all symbolically embodied by the presented Eye.
The texts also describe ritual actions, likely performed on the king’s mummy or funerary statues, involving anointing with sacred oils or cosmetics in the form of the Eye: “Osiris Unas, the sound Eye of Horus is being rubbed on your face.”
The constant repetition underscores the vital importance of these rituals. By ritually bestowing the Eye of Horus upon the deceased pharaoh, the priests affirmed his identity with Horus, ensured his protection against malevolent forces in the afterlife, and guaranteed his restoration, wholeness, and eternal life, just as Horus’s eye was restored and Osiris was revived. The Eye was a tangible link between the deceased king, his divine counterpart Horus, and the promise of rebirth.
Wadjet, the Eye of Ra, and Naming Conventions
The symbolism of divine eyes in ancient Egypt is complex, with the Eye of Horus often being confused or used interchangeably with another potent symbol: the Eye of Ra. While distinct in origin and primary meaning, their functions and iconography sometimes overlapped.
As mentioned, early Egyptian cosmology associated Horus’s eyes with the celestial bodies: the right eye was the sun, and the left eye was the moon. The eye lost to Set was typically the left, lunar eye. However, the right, solar eye, became linked with the supreme sun god Ra. This created a theological puzzle, as Ra (often identified with Atum) was mythologically Horus’s great-great-grandfather in the Heliopolitan cosmogony. By the New Kingdom (c. 1550-1070 BCE), a clearer distinction often emerged: the Eye of Ra was predominantly solar, representing the sun’s fierce power and light, while the Eye of Horus was primarily lunar, symbolizing healing, protection, and the moon’s cycles.
Further complicating matters is the origin of the Eye of Ra symbol. Unlike the Eye of Horus, which stemmed from Horus’s personal injury, the “Eye of Ra” initially wasn’t just a symbol but an active, independent aspect of Ra’s power, often personified as a goddess. According to myth, Ra sent forth his “Eye” – often in the form of a fierce lioness goddess like Sekhmet or a cat goddess like Bastet – to punish humanity for plotting against him or neglecting his worship. This Eye was an instrument of divine wrath and retribution.
Therefore, while both Eyes eventually appeared as protective amulets, their core connotations differed:
- Eye of Horus (Wadjet/Wedjat): Primarily symbolizes protection, healing, wholeness, restoration, sacrifice, and lunar connections.
- Eye of Ra: Primarily symbolizes divine power, authority, destructive force, vengeance, purification through destruction, and solar connections.
Despite these distinctions, both could be interpreted as protective. The Eye of Ra protected Ra’s divine order by eliminating threats, and its destructive power could be seen as purifying the world for restoration according to his will. The Eye of Horus offered direct protection and healing to the individual.
Iconographically, a common modern convention holds that the Eye of Horus is a left eye (with the characteristic spiral curling to the right below it), while the Eye of Ra is a right eye (with the spiral curling to the left). However, ancient Egyptian artists did not strictly adhere to this rule, and depictions of the Eye of Horus can be found facing either direction. Context is often key to distinguishing them.
The Eye symbol could also incorporate other elements. Sometimes it was depicted with an arm extending from it, offering gifts, particularly in funerary contexts. Frequently, it was flanked by the two protective goddesses representing the unified kingdom:
- Nekhbet: The vulture goddess, symbolizing Upper (Southern) Egypt.
- Wadjet: The cobra goddess, symbolizing Lower (Northern) Egypt.
It is this association with the cobra goddess Wadjet that gave the Eye of Horus its most common Egyptian name: the Wadjet Eye.
But who or what exactly was Wadjet? Originally, Wadjet was an ancient goddess worshipped in the Predynastic era, particularly associated with the city of Per-Wadjet (Buto) in the Nile Delta (Lower Egypt). She was the counterpart to the vulture goddess Nekhbet of Upper Egypt. As Egypt unified, these two goddesses became potent symbols of their respective regions and, together, represented the sovereignty of the pharaoh over the “Two Lands.” Wadjet, often depicted as a cobra or a cobra-headed woman, became the uraeus serpent worn on the pharaoh’s crown, a symbol of divine authority and protection.
Her connection to the Eye symbol might stem from conflation with the Eye of Ra myth. One story tells how Ra sent his eye (personified as a goddess, potentially Wadjet or another like Hathor) to find his lost children, Shu (air) and Tefnut (moisture). Upon their successful return, Ra wept tears of joy, from which the first humans were created. As a reward, Ra placed the goddess (Wadjet) upon his brow as the uraeus. Because the uraeus often encircled the sun disk in depictions of Ra or Ra-Horakhty, the protective cobra goddess became linked to the solar eye, and by extension, possibly confused with the lunar Eye of Horus.
Thus, the term “Wadjet” (or its variations Wedjat, Udjat – ancient Egyptian writing lacked vowels, making exact pronunciation speculative) could refer to:
- The cobra goddess herself.
- The land of Lower Egypt.
- The protective uraeus symbol.
- The Eye of Horus symbol.
- The Eye of Ra symbol.
Understanding the specific context is crucial for interpretation.

A Window into the Brain? The Anatomical Theory
While traditionally understood through mythological and magical lenses, the Eye of Horus has attracted intriguing, albeit speculative, modern interpretations. A fascinating hypothesis, proposed by neurosurgeons at the Mayo Clinic, suggests the symbol might also encode a sophisticated understanding of human brain anatomy.
This theory draws a connection between the distinct parts of the Eye of Horus symbol and the ancient Egyptian system of heqat fractions. These fractions (1/2, 1/4, 1/8, 1/16, 1/32, 1/64) were used for measuring quantities of grain and beer, and visually, they resemble parts of the Wadjet eye. The Mayo Clinic study proposes that each fractional part of the eye corresponds not only to a measurement but also to one of the six senses, linked to specific neuroanatomical structures:
- Smell (1/8): The part of the eye symbol closest to the nose (medial) is argued to correspond in shape and relative position to the olfactory trigone/bulb area in the brain.
- Sight (1/4): The pupil itself, representing the primary sense associated with the eye.
- Thought (1/2): The eyebrow-like shape above the eye is compared to the corpus callosum, the large bundle of nerve fibers connecting the brain’s two hemispheres, crucial for higher cognitive functions and coordinated thought.
- Hearing (1/16): The part extending horizontally towards the ear (lateral) is suggested to align with the auditory processing areas (Brodmann areas 41 and 42) in the temporal lobe.
- Taste (1/32): The descending, curved spiral line is proposed to resemble the shape and location of taste pathways within the brainstem.
- Touch (1/64): The straight, tear-like line descending vertically is likened to the somatosensory pathways transmitting touch sensations.
The researchers demonstrated this by overlaying the Eye of Horus symbol onto a mid-sagittal (side view, middle cut) image of the human brain, noting the apparent alignment of these components with specific functional regions.
While ancient Egyptian medicine was remarkably advanced for its time, with evidence of practices like trepanation (skull surgery) found on mummies, the extent of their detailed knowledge of brain function remains debated. The physicians who published this study readily acknowledge that their interpretation is based on pattern recognition and hypothesis – a compelling visual correlation rather than direct historical or textual evidence. It remains a speculative but thought-provoking possibility that the ancient Egyptians embedded anatomical knowledge within this sacred symbol.
Enduring Meanings of the Eye of Horus
The Eye of Horus stands as a testament to the richness and complexity of ancient Egyptian belief systems. Its journey through millennia saw it accrue multiple layers of meaning, each contributing to its enduring power.
Primarily, it was the ultimate symbol of divine protection. From the pharaoh, the living Horus, seeking safeguarding in life and passage into eternity, its protective power extended through amulets to nobles and commoners alike, warding off evil, illness, and danger.
It embodied restoration and healing. Stemming from the myth of Horus’s eye being violently lost and magically made whole, it represented the overcoming of injury, the return to completeness, and the triumph of order over chaos – concepts vital both for physical well-being and the promise of resurrection in the afterlife.
It was intrinsically linked to kingship and divine authority. As the symbol of the son of Osiris and the rightful heir to the throne, the Eye affirmed the pharaoh’s legitimacy and his role as the maintainer of Ma’at (cosmic order) on earth.
It held celestial significance, representing the moon in its cycles of waxing and waning, mirroring the themes of loss and restoration inherent in its myth.
It became intertwined with the Eye of Ra, representing the sun’s power, and with the goddess Wadjet, symbolizing Lower Egypt and the protective force of the uraeus cobra.
And perhaps, as modern interpretations suggest, it even held veiled references to the very structure of human consciousness and sensory perception within the brain.
Whether carved on temple walls, painted in tombs, inscribed on papyri, or worn as a personal amulet, the Eye of Horus was far more than mere decoration. It was a focal point of potent magical and religious power, offering solace, strength, and the promise of renewal to the ancient Egyptians.
