This concept is especially unique because no single story was more accurate than another, but rather the truth was a mix of them all. The ancient Egyptian mythology often had many different explanations for the same phenomenon. The ancient Egyptians created several enneads as their unification under Dynasty I brought numerous local cults into contact with one another. Egyptologists conventionally transcribe it as Pesedjet. Its original pronunciation is uncertain, since hieroglyphs do not record vowels, but may have been /piˈsiːcʼat/ in Old Egyptian, /piˈsiːtʼaʔ/ in Middle Egyptian, and /pəˈsiːtʼə/ in Late Egyptian. The term was a calque of the Egyptian name, written psḏt and also meaning 'the Nine'. The English name ennead is a borrowing via Latin of the Greek name enneás ( ἐννεάς), meaning 'the nine'. In addition to Memphis having its own creation myth, the Ogdoad (of the city of Hermopolis) centered around physical creation and eight primordial gods was another creation story that existed at the same time. As close as Memphis (also within modern Cairo), the priests of Ptah celebrated him as superior to the Nine. Its claims to preeminence by its Heliopolitan priests were not respected throughout Egypt. The Great Ennead was only one of several such groupings of nine deities in ancient Egypt. The Ennead sometimes includes Horus the Elder, an ancient form of the falcon god, not the son of Osiris and Isis. The Ennead or Great Ennead was a group of nine deities in Egyptian mythology worshipped at Heliopolis: the sun god Atum his children Shu and Tefnut their children Geb and Nut and their children Osiris, Isis, Set, and Nephthys.
