Ennead

n. (from Greek meaning the nine) number 9; group or set of nine

For the neo-Platonist work by Plotinus, see Enneads.For the Latin epic, see Aeneid.The Ennead (Greek , meaning "the nine") consists of a grouping of nine  deities, most often appearing in the context of Egyptian mythology. As a three of threes, the number nine became associated with great carnal  power, and ancient peoples considered groupings of nine deities very important.The ancient Egyptians set up multiple Enneads. Pyramid Texts mention the Great Ennead, the Lesser Ennead, the Dual Ennead, plural Enneads, and even the Seven Enneads. Some pharaohs set up Enneads that incorporated themselves; most notably, Seti I in his temple at Redesiyah worshipped the Ennead that combined six important deities with three deified forms of him.
