The tale begins in the First Time, the Zep Tepi, when the gods walked among men and the land of Egypt was divided between the lush Nile valley and the harsh, unforgiving desert. Osiris, the first-born son of Geb and Nut, sat upon the throne as a wise and benevolent ruler. He taught the people the secrets of agriculture, the making of beer and wine, and the laws of justice. Beside him stood Isis, his sister-wife, whose mastery of magic and wisdom was unsurpassed. Together, they brought an era of prosperity and peace that had never been seen before. However, in the shadows of this golden age, a dark envy festered. Set, the brother of Osiris and the god of storms, chaos, and the red desert, coveted the crown. Set viewed his brother's pacifism as weakness and believed that only a ruler as fierce as the desert winds could truly command the Two Lands.
Set's betrayal was as calculated as it was cruel. Through a grand deception involving a chest perfectly measured to Osiris's dimensions, Set trapped his brother and cast him into the Nile. When Isis eventually recovered the body, Set discovered her hiding place and, in a fit of rage, tore the corpse of Osiris into fourteen pieces, scattering them across the length and breadth of Egypt. This act was meant to ensure that Osiris could never find peace in the afterlife, for a soul without a body was doomed to wander. Yet, Isis did not despair. With the help of her sister Nephthys and the jackal-headed god Anubis, she traversed the marshes and the mountains, collecting every fragment of her husband. Through the first rites of mummification and her potent incantations, she briefly restored Osiris to a semblance of life. In that miraculous moment of rebirth, Horus was conceived—the heir who would one day avenge his father and reclaim the throne.
Horus was raised in secret within the papyrus thickets of the Nile Delta, at a place called Khemmis. Isis used all her cunning to protect the child from Set's venomous serpents and scouring winds. As Horus grew, his strength and his purpose became clear. He was the sky-god, whose right eye was the sun and whose left eye was the moon. When he reached adulthood, he emerged from the marshes to challenge his uncle before the divine tribunal of the Ennead. The conflict between Horus and Set was not a single battle but a series of brutal, transformative contests that spanned eighty years. They shifted shapes into hippopotami, they raced in boats of stone, and they struck at one another with the fury of cosmic forces. It was during one of these savage encounters that Set gained a momentary advantage. In a flurry of violence, Set reached for the face of Horus and gouged out his left eye—the lunar eye—tearing it into six distinct pieces and throwing them into the darkness.
Horus was left blinded and broken, but the balance of Ma'at—the cosmic order—could not allow such a theft to stand. Thoth, the ibis-headed god of wisdom, writing, and calculations, went out into the world to find the fragments of the shattered eye. With his infinite patience, Thoth gathered the six pieces from the corners of the earth. Using his divine saliva and the power of his spells, he reassembled the eye. However, when the pieces were joined, they only totaled sixty-three sixty-fourths of a whole. To complete the restoration, Thoth added a final, mystical sixty-fourth piece, creating the 'Wadjet'—the Sound Eye, the Whole One. This eye was no longer merely a sensory organ; it was a talisman of immense power, containing the essence of healing, protection, and the restored light of the moon.
When Thoth returned the eye to Horus, the young god felt his strength return a thousandfold. He was now ready to end the conflict and take his place as the living Pharaoh. But Horus understood that his victory would be hollow if his father remained a mere shadow in the depths of the earth. He knew that Osiris resided in the Duat, the mysterious underworld through which the sun god Ra traveled every night. The Duat was a realm of perilous gates, fiery lakes, and monstrous entities that tested the souls of the deceased. To reach his father, Horus had to descend from the realm of the living into the kingdom of the silent. He carried with him the Wadjet, the eye that had been broken and made whole again.
