Osiris is one of the oldest gods for whom records have been found; one of the oldest known attestations of his name is on the Palermo Stone of around 2500 BC. He was widely worshiped until the suppression of the Egyptian religion during the Christian era. The information we have on the myths of Osiris is derived from allusions contained in the Pyramid Texts (ca. 2400 BC), later New Kingdom source documents such as the Shabaka Stone and the Contending of Horus and Seth, and, much later, in narrative style from the writings of Greek authors including Plutarch and Diodorus Siculus.

Osiris was not only a merciful judge of the dead in the afterlife, but also the underworld agency that granted all life, including sprouting vegetation and the fertile flooding of the Nile River. He is described as the "Lord of love", "He Who is Permanently Benign and Youthful" and the "Lord of Silence". The Kings of Egypt were associated with Osiris in death — as Osiris rose from the dead they would, in union with him, inherit eternal life through a process of imitative magic. By the New Kingdom all people, not just pharaohs, were believed to be associated with Osiris at death if they incurred the costs of the assimilation rituals

Osiris was at times considered the oldest son of the Earth god Geb, and the sky goddess, Nut as well as being brother and husband of Isis, with Horus being considered his posthumously begotten son. He was later associated with the name Khenti-Amentiu, which means "Foremost of the Westerners" a reference to his kingship in the land of the dead. As the Ancient Egyptians considered the blessed dead "the living ones" so as ruler of the dead Osiris is also sometimes called "king of the living".

Through the hope of new life after death Osiris began to be associated with the cycles observed in nature, in particular vegetation and the annual flooding of the Nile, through his links with Orion and Sirius at the start of the new year.

Osiris is represented in his most developed form of iconography wearing the Atef crown, which is similar to the White crown of Upper Egypt (but with the addition of two feathers at each side-- see Atef crown (hieroglyph)). He also carries the crook and flail. The crook is thought to represent Osiris as a shepherd god. The symbolism of the flail is more uncertain with shepherds whip, fly-whisk, or association with the god Andjety of the ninth nome of Lower Egypt proposed. He was commonly depicted as a green (the color of rebirth) or black (alluding to the fertility of the Nile floodplain) complexioned pharaoh, in mummiform (wearing the trappings of mummification from chest downward).

When the Ennead and Ogdoad cosmogenies became merged, with the identification of Ra as Atum (Atum-Ra), gradually Anubis (Ogdoad system) was replaced by Osiris, whose cult had become more significant. Anubis was said to have given way to Osiris out of respect, and, as an underworld deity. Anubis was Set's son in some versions, but because Set became god of evil, he was subsequently identified as being Osiris' son. Abydos, which had been a strong centre of the cult of Anubis, became a centre of the cult of Osiris. Because Isis, Osiris' wife and sister, represented life in the Ennead, it was considered somewhat inappropriate for her to be the mother of a god associated with death such as Anubis, and so instead, it was usually said that Nephthys, the other of the two female children of Geb and Nut, was his mother.

Later, when Hathor's identity (from the Ogdoad) was assimilated into that of Isis, Horus, who had been Isis' husband (in the Ogdoad), became considered her son, and thus, since Osiris was Isis' husband (in the Ennead), Osiris also became considered Horus' father. Attempts to explain how Osiris, a god of the dead, could give rise to Horus, who was thought to be living, led to the development of the Myth of Osiris and Isis, which became a central myth in Egyptian mythology. The myth described Osiris as having been killed by his brother Set who wanted Osiris' throne. Isis briefly brought Osiris back to life by use of a spell that she learned from her father.

This spell gave her time to become pregnant by Osiris before he again died. Isis later gave birth to Horus. As such, since Horus was born after Osiris' resurrection, Horus became thought of as representing new beginnings, and vanquished Set. This combination, Osiris-Horus, was therefore a liferebirth deity, and thus associated with the new harvest each year. Afterward, Osiris became known as the Egyptian god of the dead, Isis became known as the Egyptian goddess of the children, and Horus became known as the Egyptian god of the sky.

Ptah-Seker (who resulted from the identification of Ptah as Seker), who was god of re-incarnation, thus gradually became identified with Osiris, the two becoming Ptah-Seker-Osiris (rarely known as Ptah-Seker-Atum, although this was just the name, and involved Osiris rather than Atum). As the sun was thought to spend the night in the underworld, and subsequently be re-incarnated, as both king of the underworld, and god of reincarnation, Ptah-Seker-Osiris was identified.

Since Osiris was considered dead, as god of the dead, Osiris' soul, or rather his Ba, was occasionally worshipped in its own right, almost as if it were a distinct god, especially so in the Delta city of Mendes. This aspect of Osiris was referred to as Banebdjedet, which is grammatically feminine (also spelt "Banebded" or "Banebdjed" which literally means The ba of the lord of the djed, which roughly means The soul of the lord of the pillar of stability. The djed, a type of pillar, was usually understood as the backbone of Osiris, and, at the same time, as the Nile, the backbone of Egypt.

The Nile, supplying water, and Osiris (strongly connected to the vegetation) who died only to be resurrected represented continuity and therefore stability. As Banebdjed, Osiris was given epithets such as Lord of the Sky and Life of the (sun god) Ra, since Ra, when he had become identified with Atum, was considered Osiris' ancestor, from whom his regal authority was inherited. Ba does not, however, quite mean soul in the western sense, and also has to do with power, reputation, force of character, especially in the case of a god. Since the ba was associated with power, and also happened to be a word for ram in Egyptian, Banebdjed was depicted as a ram, or as Ram-headed. A living, sacred ram, was even kept at Mendes and worshipped as the incarnation of the god, and upon death, the rams were mummified and buried in a ram-specific necropolis.

As regards the association of Osiris with the ram, the god's traditional crook and flail are of course the instruments of the shepherd, which has suggested to some scholars also an origin for Osiris in herding tribes of the upper Nile. The crook and flail were originally symbols of the minor agricultural deity Andjety, and passed to Osiris later. From Osiris, they eventually passed to Egyptian kings in general as symbols of divine authority

In Mendes, they had considered Hatmehit, a local fish-goddess, as the most important deity, and so when the cult of Osiris became more significant, Banebdjed was identified in Mendes as deriving his authority from being married to Hatmehit. Later, when Horus became identified as the child of Osiris (in this form Horus is known as Harpocrates in Greek and Har-pa-khered in Egyptian), Banebdjed was consequently said to be Horus' father, as Banebdjed is an aspect of Osiris
