Osiris: Lord of the Underworld and Judge of the Dead

At the heart of Egyptian religion stood a god who had been murdered, dismembered, and resurrected. His name was Osiris, and he was, in many ways, the most important of all the Egyptian gods. He was the god of the dead, the ruler of the underworld, the judge of souls, and the divine prototype of the pharaoh. Every dead king became Osiris, and every living king was the incarnation of his son, Horus. The myth of Osiris, the central myth of Egyptian religion, gave the Egyptians a way of thinking about death, kingship, and the meaning of life that endured for more than three thousand years.

In the mythology of the Ennead, Osiris was the son of the earth god Geb and the sky goddess Nut, and the brother-husband of Isis. He was the gentle god, the bringer of civilization, the patron of agriculture. After his murder by his brother Set, he became something more: the eternal king of the underworld, the one who sat on his throne in the Hall of Two Truths to judge the souls of the dead.

Origins: From Fertility God to Lord of the Dead

Osiris’ original domain, in the predynastic period before the unification of Egypt, appears to have been as a fertility god and a chthonic (underground) deity. His name in Egyptian, Wesir or Usir, has been translated in many ways, but the most common interpretation is “Mighty One” or “He Who Sees the Throne.” He was associated with the earth, with the fertility of the soil, and with the annual flood of the Nile.

In early times, Osiris may have been worshipped in several different local traditions, including those of Andjeti in the ninth nome of the Nile delta and Khenti-Amentiu (“Foremost of the Westerners,” a name for the god of the dead) in Abydos. As the cult of Osiris expanded and the central myth developed, these older local gods were absorbed into the figure of Osiris, and the ennead mythology gave him a genealogy and a story.

The assimilation of these older gods to Osiris is part of the broader process by which Egyptian religion was unified in the Ennead of Heliopolis. The local fertility gods and underworld gods were brought together into a single figure, and the central myth — the murder, the search, the resurrection, the judgment — became the model for the afterlife of every Egyptian.

Iconography: The Mummy, the Crown, the Crook and Flail

Osiris was typically depicted as a mummiform man, wrapped in the linen bandages of the dead, with his arms crossed over his chest. In his hands, he held the crook (heka) and the flail (nekhakha), the symbols of kingship. The crook represented the king’s role as a shepherd of his people, and the flail represented his role as the provider of grain — they had been the symbols of the pharaoh since the earliest dynasties.

On his head, Osiris wore the atef crown: a tall white crown (the hedjet, the crown of Upper Egypt) flanked by two ostrich feathers, with a small sun disk at the top. The atef crown was a particularly sacred crown, used in religious contexts rather than in everyday royal regalia. In some images, Osiris also wore a vulture headdress, identifying him with the great goddesses of Upper and Lower Egypt, and sometimes a false beard braided at the end, the symbol of divinity.

The color of Osiris’ skin is one of the most distinctive features of his iconography. In some images, his skin is green, symbolizing vegetation, fertility, and the new growth of the earth. In other images, his skin is black, symbolizing the rich black silt of the Nile and the fertility of the Egyptian soil. In still other images, his skin is white or pale, emphasizing his deathly nature. The variation reflects the different aspects of the god: the fertility of the earth, the wealth of the soil, and the stillness of the dead.

In his hands, Osiris sometimes also held the ankh (the key of life) and the was scepter (the symbol of power). The combination of the crook, the flail, the ankh, and the was was the standard set of divine regalia for the gods of the underworld, and it appears in countless statues, paintings, and tomb carvings.

The Myth: Murder, Dismemberment, Resurrection

The myth of Osiris is recounted in full elsewhere in this collection, in the long-tail page on Isis and Osiris. In summary, the story is as follows.

Osiris, the king of Egypt, was a great benefactor to the people. He taught them agriculture, established laws, and abolished cannibalism. His brother Set, consumed by jealousy, plotted to kill him. At a great banquet, Set produced a magnificent chest, promising it to whoever could fit inside it. Osiris lay down in the chest, and Set and his followers sealed it and threw it into the Nile. The chest floated out to sea and came to rest at Byblos, in modern Lebanon, where a tamarisk tree grew up around it.

Isis, Osiris’ wife, searched the world and found the body at Byblos. She brought it back to Egypt, but Set discovered it, dismembered it into fourteen pieces, and scattered them across the land. Isis searched again, found the pieces, and reassembled the body with the help of Anubis, who performed the first mummification. With her magic, Isis brought Osiris back to life, just long enough to conceive a son, Horus. After this, Osiris descended to the underworld to become its eternal ruler.

This myth, preserved in the Pyramid Texts of the Fifth Dynasty (c. 2400 BCE) and most fully told by Plutarch in De Iside et Osiride (first century CE), is the central myth of Egyptian religion. It was reenacted in the annual Festival of Khoiak at Abydos and other cult centers, and it was the basis for the entire Egyptian funerary ritual.

Osiris as Judge of the Dead

The most important role of Osiris in the Egyptian afterlife was as the judge of the dead. After the soul had passed through the twelve hours of the Duat and arrived at the deepest level of the underworld, it was led into the Hall of Two Truths (also called the Hall of Ma’at), where Osiris sat enthroned.

The scene of the judgment is preserved in countless New Kingdom papyri, the most famous being the Papyrus of Ani in the British Museum. In the painted vignettes, Osiris sits on his throne in the center of the hall, wearing the atef crown, holding the crook and flail. Before him stands the deceased, led by Anubis and presented by Horus. In the center of the hall, the great golden scales of Ma’at are operated by Anubis, and the heart of the deceased is weighed against the white feather of truth. The full ceremony is described in the weighing of the heart long-tail page.

The deceased, in the Book of the Dead, was expected to declare his or her innocence before each of the forty-two Assessor deities, each of whom represented a particular sin. After the negative confession, the heart was weighed. If the heart was light — equal to the feather — the deceased was welcomed by Osiris into the Field of Reeds, the eternal paradise of Egyptian belief. If the heart was heavy with sin, the monstrous Ammit would devour it, and the soul would be destroyed.

This judgment scene is one of the most powerful images in world mythology, and it has been compared to the Greek judgment of souls in the Myth of Er (the closing tale of Plato’s Republic), to the Norse judgment of the gods at Ragnarök, and to the Christian Last Judgment. The Egyptian version is the oldest, and the most elaborately developed.

The Cult of Osiris

The cult of Osiris was one of the most important in ancient Egypt. His main cult center was at Abydos, in the eighth nome of Upper Egypt, where his tomb was said to be located (specifically, the tomb of his head). The Temple of Seti I at Abydos, built in the Nineteenth Dynasty (c. 1279 BCE), is one of the most beautiful temples in Egypt, and it contains a remarkable series of reliefs depicting the mysteries of Osiris.

A second important center was at Busiris (called Djedu, “the pillar,” in Egyptian), in the ninth nome of the Nile delta, where the spine of Osiris was said to be buried. The temple of Osiris at Busiris was the center of a vigorous cult from the Old Kingdom onward, and the city was known throughout the ancient world as the home of the sacred pillar of Osiris.

Other important cult centers included:

Philae, on an island near the first cataract of the Nile, where the great temple of Isis was built in the Ptolemaic and Roman periods
Memphis, where the head of Osiris was said to be buried in some traditions
Heliopolis, the cult center of Ra, where the Ennead was developed
Coptos and Edfu, where the cult of Osiris and Horus was celebrated together
Athribis in the delta, where a ram-god called Khentekhtai was identified with Osiris

The triad of Abydos — Osiris, Isis, and Horus — was one of the most important divine families in Egyptian religion. The triad was worshipped throughout Egypt, and it was the model for the divine family in many other cults.

The Festivals of Osiris

The cult of Osiris was celebrated in a number of annual festivals, the most important of which was the Festival of Khoiak. Held in the month of Khoiak (the fourth month of the Egyptian calendar, around December), the festival was a great public celebration that combined mourning, procession, and reenactment of the myth.

The festival, as described by the Greek historian Herodotus and the Roman writer Plutarch, lasted for several days. The first days were given over to mourning. Statues of Osiris were carried in procession, the wailing of the women filled the streets, and the people beat their breasts in grief. The middle of the festival saw the reenactment of the murder, the search, and the resurrection, often with the help of diorite statuettes of the dead god that were buried in the fields to ensure the fertility of the soil. The festival ended with the joyful celebration of the resurrection, when Osiris was declared to be alive and well, and the new crops were blessed.

A second important festival was the Beautiful Festival of the Valley at Thebes, in which the statues of the gods were carried in procession across the Nile to visit the tombs of the dead. This festival, celebrated in the second month of the Egyptian calendar, was a time of pilgrimage, family reunion, and offerings to the deceased.

A third festival, the Feast of the Appearance at Abydos, marked the moment when the resurrected Osiris appeared to the people. This festival, like the others, was a time of pilgrimage, procession, and offerings.

Osiris and the Pharaoh

The most important political aspect of the Osiris cult was the doctrine of the kingship of Horus and the resurrection of Osiris. According to this doctrine, the living pharaoh was the incarnation of Horus, the son of Osiris, while the dead pharaoh became Osiris, the ruler of the underworld. The continuity of the dynasty was thus a continuation of the cosmic struggle of order against chaos, played out in the valley of the Nile.

In practical terms, this doctrine meant that every pharaoh, upon his accession, became Horus, and upon his death, became Osiris. His wife, the queen, was associated with Isis, and his mother, the queen-mother, was also associated with Isis. The divine family of the ruling pharaoh was thus a model of the divine family of Osiris, Isis, and Horus.

The doctrine also had a powerful effect on the location of the royal tombs. The pharaohs of the First and Second Dynasties were buried at Abydos, the cult center of Osiris, in order to be near the god in the afterlife. The pharaohs of the Old Kingdom were buried near Memphis, in the great pyramids of Giza and Saqqara. The pharaohs of the New Kingdom were buried in the Valley of the Kings in the Theban hills, but the cult of Osiris continued to be celebrated at Abydos, and the pharaohs of the New Kingdom built memorial chapels there.

The Mysteries of Osiris

In the Late Period (664-332 BCE) and the Ptolemaic period, the cult of Osiris developed into a system of mysteries, in which the central myth was enacted and the initiates were given a special knowledge of the divine. The mysteries of Osiris, like the Eleusinian Mysteries of Demeter and Persephone in Greece, were a kind of secret ritual in which the death and resurrection of the god was celebrated, and in which the initiates were promised a share in the life of the god.

The mysteries were celebrated at Abydos, Busiris, and Philae, and they were open to all Egyptians, not just to the priests. The initiates underwent a period of purification, they took part in the reenactment of the myth, and they received a special name that identified them with the god. The most famous account of the mysteries is in Plutarch’s De Iside et Osiride, which preserves many of the rituals in detail.

The mysteries of Osiris were an important forerunner of the later mystery religions of the Greco-Roman world, including the Eleusinian Mysteries and the cult of Mithras. They shared the central theme of the death and resurrection of a divine figure, and they promised the initiates a share in the life of the god.

The Identification with Other Gods

As with the other Egyptian gods, Osiris was identified with a number of local and foreign deities over the centuries. He was identified with Andjeti of the ninth nome of the delta, with Khenti-Amentiu (“Foremost of the Westerners”) of Abydos, with Seker of Memphis (a god of the dead who was combined with Osiris as Seker-Osiris), and with Wenennefer, a name meaning “the eternally beautiful,” which became one of the most common epithets of Osiris in the New Kingdom.

In the Greco-Roman period, Osiris was identified with Dionysus and Hades. The cult of Serapis, established by the Ptolemies in Alexandria, was a syncretic god combining the Egyptian Osiris-Apis (a bull-god of Memphis) with the Greek Hades and Zeus. Serapis was worshipped throughout the Hellenistic world as a universal god of the afterlife, and his cult was one of the most important in the Roman Empire.

The identification of Osiris with Dionysus, in particular, was important in the spread of the cult. The Greek myths of Dionysus — the god of wine, the bringer of civilization, the god who was killed and reborn — were already very similar to the Egyptian myths of Osiris, and the syncretism was natural. Plutarch discussed the identification at length in De Iside et Osiride, and the cult of Dionysus-Osiris was established throughout the Roman world.

Osiris and the Egyptian Afterlife

The most enduring aspect of the Osiris cult is its central role in the Egyptian afterlife. The deceased, in the Book of the Dead and in the Coffin Texts, was expected to identify with Osiris, to take on his name, and to be given a place in the underworld. The phrases “Osiris NN” (where NN is the name of the deceased) appear countless times in the funerary texts, and the deceased was expected to know the spells that would allow him or her to pass through the dangers of the Duat and to be judged worthy of the Field of Reeds.

The identification of the deceased with Osiris also had a powerful effect on Egyptian funerary art. The dead pharaoh was depicted as Osiris, with the atef crown and the crook and flail. The dead noble was depicted as Osiris, with green or black skin, lying in his coffin. The dead were referred to as “the Osiris NN,” and the tomb was called “the house of Osiris.”

The cult of Osiris thus provided the Egyptian religion with its most powerful and most enduring framework for thinking about death. The idea that the dead became Osiris, that the soul was judged, and that the worthy were given a place in the Field of Reeds was the model for the entire Egyptian afterlife. The cult did not die with the pharaohs; it survived in the Coptic Christian tradition, in the Islamic folk traditions of Egypt, and in the modern popular imagination.

The Lasting Power of Osiris

The myth of Osiris has been one of the most influential in world mythology. It has inspired poets and philosophers from Plutarch to Freud (whose first book, Der Moses des Michelangelo, drew on the Egyptian myth), and it has been the model for countless later traditions of the dying-and-rising god. A reader who wants to understand the Christian theology of resurrection, the classical Greek myth of Dionysus, or the Hindu avatar of Vishnu would do well to start with the cults of Abydos. The myth of Isis and Osiris is the floor on which a great deal of later western religious imagination was built.

The cult of Osiris also had a powerful effect on the development of early Christianity. The story of the god who died, was buried, and rose from the dead was already familiar to the Egyptian converts to Christianity, and the iconography of Osiris — the god enthroned in the underworld, the mummified body, the judgment of the dead — has been recognized as one of the most important sources of Christian iconography. The early Christian art of the resurrected Christ in his tomb, the Last Judgment, and the weighing of the soul all have Egyptian antecedents in the cult of Osiris.

Osiris, the murdered-and-resurrected god of Egypt, has been one of the most powerful religious figures in human history. His myth has been told for more than four thousand years, and it continues to be told in countless books, paintings, and films. The figure of Osiris — the gentle king, the murdered god, the ruler of the underworld, the judge of the dead — is one of the great figures of world mythology.
