The Heliopolitan Ennead & Cosmogony
Nine gods in a single family tree — the theology that frames the story of Osiris.
Also: Ennead · Pesedjet · Heliopolis · Iunu · On · Atum · nine gods
At Heliopolis, near modern Cairo, Egyptians told of the creator Atum, who arose from the waters and brought forth the first divine pair, Shu (air) and Tefnut (moisture). From them came Geb (earth) and Nut (sky), and from those Osiris, Isis, Seth, and Nephthys. This family of nine gods, the Ennead, organized much of Egyptian theology and frames the Osiris story.
In short
The creation theology of Heliopolis (Iunu), in which the self-developing creator Atum brings forth nine gods — Atum, Shu and Tefnut, Geb and Nut, and Osiris, Isis, Seth, and Nephthys — known collectively as the Ennead.

How the idea developed across Egypt
Attested from the Pyramid Texts (Old Kingdom) and foundational throughout Egyptian religion; the term 'Ennead' (pesedjet, 'the Nine') could be applied loosely to other groupings of gods.
'Ennead' is a Greek-derived label for the Egyptian pesedjet ('the Nine'); the membership is most standard at Heliopolis but varies elsewhere.
