For the Ancient Egyptians, the cycle of life  itself began and ended with Isis and Osiris. Their story is one of the oldest known myths, and  it informed spiritual beliefs, power structures, and gender roles in Ancient Egypt and beyond. And  who wouldn’t be drawn to a tale that has it all? And by all, I mean devious party tricks,  sibling rivalry, shape-shifting quests, true love – and a missing penis. In 1922, the unsealing of King Tutankhamun’s  tomb opened a portal to Ancient Egypt. In  the burial chamber, carvings on the wall show  the young Pharaoh traveling to the afterlife. Here he is welcomed by Isis, mother  of Pharaohs and goddess of protection, and Osiris, king of the underworld. Two of Egypt’s most powerful Gods, Isis and Osiris appear throughout funerary  texts and art. King Tut’s iconic death mask bears Osiris’ likeness, while symbols  of Iksis are etched across his coffin. The influence of these two deities  extends far beyond mummies and tombs. Long before Isis and Osiris,  there was the creator God Atum. Some accounts identify him as the  creator of Shu, god of dry air, and Tefnut, goddess of moisture, who were the  parents of Geb, the earth, and Nut, the sky. Other versions say that Atum fashioned Geb  and Nut himself, separating earth from sky when he discovered their illicit affair. Either way, it’s a formidable family tree. Geb and Nut had four children:  Isis, Osiris, Set, and Nephthys. These deities paired off in the womb, with  Isis and Osiris falling for each other and Set and Nephthys forming their own bond. As first born, Osiris became ruler of the earth. He was essentially the creator of society,  who brought law, farming, religion, and education to the people. Not to be outdone,  Isis brought medicine, healing…and beer brewing. If Osiris stood for order, Set stood for  chaos. Even with the restrained Nephthys by his side, he couldn’t contain  his desire to destroy his brother. Set was known for causing storms,  war, and general malaise. But his most vicious plan began with a party. At this gathering, Set produced an ornate chest and proposed a game: whoever could fit  inside the chest, could keep it. All the Gods tried to squeeze in, but none succeeded – for Set  had designed the chest for Osiris’ body alone. As his brother settled in, Set slammed the  chest shut, sealed it, and flung it in the Nile. As Set seized power over Egypt, the chest floated  down the Nile and washed up at the kingdom of Byblos. Here it merged with the trunk of a cedar tree, which the King promptly cut down and used to prop up his palace - not knowing that Osiris’ body was inside. The image of this pillar containing the  imprisoned God became the djed , a symbol of stability in Egyptian architecture. Back with the Gods, things were anything but stable. Furious, Isis vowed to find her  husband and put an end to Set’s rule. She and Nephthys took flight as falcons, questioning  everyone they could find for news of Osiris. Eventually, a group of children  pointed them in the right direction. Landing on the shores of Byblos, Isis transformed  into a human and set about charming the palace maids--eventually gaining the favor of the queen. Now an undercover nanny, Isis took to bathing the infant prince in fire in order to instill some  godly strength – but when the king discovered her actions he was so terrified that he promised  to give her anything in exchange for safety. Of course, Isis demanded the chest. She brought Osiris’ body back to the banks of the Nile, hiding it in the reeds  until she could figure out how to revive him. But Set found the body, hacking it into fourteen  pieces and scattering them across Egypt. Once again, Isis set out in search of Osiris. She soon tracked down thirteen parts of the  body, which she lovingly stitched back together. But they had a little problem: Osiris’  penis had been eaten by a fish. Isis had come too far to be thwarted by this. Some  say that she fashioned a new member for Osiris, with others adding that she drew out his  last sexual powers with her beating wings. Either way, the two used Osiris’ final moments on  earth to conceive an heir. By the power of Isis, Osiris was briefly revived, given a proper burial,  and sent safely to the realm of the dead. Here he was resurrected as the king of the afterlife,  or Duat, where he would rule for eternity. In the wake of Osiris’ departure, Isis raised  their son Horus in hiding. Under her guidance, he grew into a strapping young God who defeated  Set to assume his rightful rule over Egypt. The epic battle between Horus and Set was  sometimes used as a metaphor for the war between Upper and Lower Egypt, with Horus’ triumph  standing for the unification of the region. The story served as a guide to death for all  Ancient Egyptians. Isis’ retrieval of the chest from Byblos informed the belief that Egyptians  should only be laid to rest on Egyptian soil, and the second part of her quest highlights the  importance of protecting the body after death. Isis painstakingly searched for  and reassembled Osiris’ body, thus constructing what can be  considered the first mummy. Her re-creation of the penis corresponds to  the belief that the body should be buried  intact. During mummification, embalmers  would construct absent body parts for the dead. This ensured that they would travel to  the underworld in the best possible shape. For King Tut, this meant being buried  with his penis propped at a 90-degree angle, a feature which scholars have  linked to Osiris’ postmortem fertility. Embalmers often placed the  dead in decorated coffins, which eventually became kanthropoid or  human-shaped to resemble Osiris’ chest. Many bore the face of the God, and were  decorated with the wings of Isis and Nephthys. The Pyramid texts of the Old Kingdom frame Osiris  as king and judge of the afterlife These writings were a set of utterances and hymns, intended for  royalty to ensure safe passage to the afterlife. To reach paradise, or the field of reeds, you  had to meet with Osiris in the Hall of Truth. Here he weighed your heart against  the Feather of Truth, which you’d hopefully kept nice and light by  steering clear of bad thoughts and actions. If your heart wasn’t weighed  down, Osiris let you pass. This encounter between god and mortals was  extended in the Coffin Texts of the Middle Kingdom, which emphasize Osiris as the  judge of all people regardless of class. In the New Kingdom, which occurred between  the sixteenth and eleventh century BCE, the Book of the Dead became the  most popular guide to the afterlife. A collection of funerary spells and  guidelines written over hundreds of years, the Book guided the dead through face-offs  with demons, confessions to Gods, the weighing of the heart, and other judgments  of the spirit. Isis and Osiris appear throughout these texts, judging or guiding the  dead through their spiritual reckonings. While Osiris reveals the challenges and promises  of the afterlife, Isis stands for life itself. From food and water to the nourishing  powers of medicine and maternal instincts, Isis presided over living things. She was widely worshiped as the Protectress and Mother of All Pharaohs, and is referred  to as “The Great One” in the Pyramid texts. Her behavior following the death  of Osiris epitomizes the ingenuity and perseverance that she was beloved for. This triumph indicates her  possession of mighty magic, which allows her to shapeshift, revive  the dead, and protect the vulnerable. The awe-inspiring powers of Isis can be linked  to the elevated role of women in Ancient Egypt. Women had autonomy over  marriage, property, and finances, and could be Pharaohs in their own right. Non-royal women also served as scribes, doctors, and religious officials, carrying out different  forms of protection that Isis also embodied. Over time, Isis became the supreme Egyptian God. Her temples were erected across North Africa, as well as Crete, Pompeii, and Northern Europe. The  Roman cult of Isis is still shrouded in mystery, but we do know that her followers  launched a model ship filled with offerings to the Goddess every year. In the classical world, she was more generally associated with the Goddess of  food and fertility Demeter, and her cult in Rome came to rival that of Christianity. It’s also been noted that Christian iconography of the Madonna and child borrows from the  image of Isis protecting the infant Horus. From mummification to mothering, she  informed a host of practices and ideals. From temple paintings to burial  practices to secret rituals, Osiris and Isis infused ancient  iconography and beliefs. Our knowledge of their story myth comes  from a similarly diverse range of sources. Found on the walls of ancient pyramids - and  aptly named the Pyramid Texts - the oldest religious writings in the world reference the  grisly murder of Osiris. Later texts like the Chester Beatty Papyrus and the Shabaka Stone also allude to this event and its fallout, while classical historians like Plutarch and Diodorus Siculus wrote their own versions of the myth. While the premature death of Osiris and his  separation from Isis could be seen as a tragic tale, the story reveals the Ancient Egyptian  belief that the boundaries between material and spiritual, life and death, are porous. For the Ancient Egyptians, Osiris offered a poignant reminder that life  was fragile – even for a God. As the great protector, Isis offered  guidance on that fragile path and ensured that the channels between  the living and the lost were always open.
