How did Osiris die in Egyptian Mythology?
Osiris’ reverence in ancient Egypt was primarily centered around his death. Known as the god of the afterlife, vegetation and resurrection, Osiris was worshiped as a divine king. Thus he was considered the ruler of the afterlife and the judge of the dead.
In the article below, we delve right into the myths surrounding the death of Osiris in ancient Egyptian mythology.
Who killed Osiris and why?

Unknown to Osiris, Seth purposely built the casket to fit Osiris. Once the casket was sealed shut, Seth threw the casket into the Nile
In Egyptian mythology, Osiris was killed by his brother Seth (also known as Set). The reason for the murder was mainly motivated by jealousy and a thirst for power. Osiris was the king of Egypt and widely revered for his wisdom and benevolence. Seth, feeling envious of his brother’s popularity and position, sought to eliminate Osiris to take the throne for himself.
Source of Seth’s hatred of Osiris
The source of Seth’s hatred towards Osiris is rooted in their family dynamics and power struggle. In Egyptian mythology, both Seth and Osiris were siblings and sons of Geb and Nut, making them part of the divine family. Seth was associated with chaos, storms, and desert lands, while Osiris was associated with fertility, agriculture, and kingship.
Seth’s jealousy and animosity towards Osiris grew when Osiris became the ruler of Egypt and enjoyed the love and admiration of the people. Moreover, Seth’s wife, Nephthys, was infatuated with Osiris, which added to his resentment.

The tipping point came when Seth, consumed by envy and desire for power, conspired to kill Osiris and take his place as the ruler of Egypt. The exact motivation for Seth’s actions may vary in different accounts, but the underlying theme is the struggle for power and dominance among divine beings.
Murder of Osiris
In Egyptian mythology, Seth (Set) killed Osiris through a treacherous plot. According to the myth, Seth tricked Osiris into entering a beautiful, intricately decorated chest or coffin, claiming that whoever could fit inside it perfectly would receive the chest as a gift. Once Osiris was inside, Seth sealed the chest and threw it into the Nile River, drowning Osiris.
Some variations of the myth suggest that Seth may have enlisted the help of accomplices to carry out the murder. Regardless of the specific details, the common thread in the myth is Seth’s deceitful and malicious act leading to Osiris’ death.
The dismembering of Osiris’ body
After Osiris’ death, his body was dismembered by his brother Seth, who was jealous and resentful of Osiris’ power and popularity. Seth cut Osiris’ body into multiple pieces and scattered them across Egypt to prevent him from being properly buried and resurrected.
Upon learning of this gruesome act, Osiris’ wife and sister, Isis, embarked on a quest to retrieve and reassemble his body. She traveled throughout Egypt, collecting the scattered body parts, and carefully put them back together. However, there was one part missing: Osiris’ phallus, which had been thrown into the Nile and eaten by a fish.
Osiris – the first mummified king in ancient Egypt
The ancient Egyptians believed that by mummifying the deceased, they could ensure the person’s safe journey to the afterlife and eventual resurrection, much like Osiris had experienced. The mummification process involved preserving the body and preparing it for its journey to the realm of the dead.
Despite this missing piece, Isis successfully reassembled the rest of Osiris’ body and performed powerful rituals, which brought him back to life temporarily. During this time, they conceived their son Horus.
The above explains why during the mummification process, priests and embalmers often recited prayers and rituals that invoked the power of Osiris and other deities associated with death and the afterlife. These ceremonies were believed to ensure the deceased’s safe passage and resurrection in the realm of Osiris.
Did you know…?
- According to one tradition, all of Osiris’ body parts were recovered by Isis except for his phallus. It was believed that this missing piece remained in the land, ensuring its fertility and prosperity.
- In the search and reassembling of Osiris’ body, Isis solicited the help of Egyptian deities like Nephthys, Thoth, and Anubis. It’s believed that Thoth, the Egyptian god of the moon, knowledge, and time, provided guidance. Anubis, the god of the dead, developed the art of embalming to preserve Osiris’ divine beauty.

Resurrection of Osiris
Osiris’ story also provided a spiritual context for the mummification process. His death and resurrection symbolized the eternal life that the ancient Egyptians sought in the afterlife. Through mummification and proper burial, they hoped to secure a similar destiny of immortality.
Osiris’ resurrection, even if temporary, affirmed his role as the god of the afterlife and the symbol of regeneration and rebirth in Egyptian mythology. He became associated with the cyclical nature of life and death, and his story became a central theme in ancient Egyptian beliefs surrounding death and the afterlife.

As the god of the afterlife and resurrection, Osiris represented the cycle of life, death, and rebirth, which was intricately tied to the process of mummification.
