In Egyptian mythology, Nun (TR:214) (LH:20) (TL:234), hieroglyph: , i.e. water wave symbol and three pots, symbolic of water "sound", aka “Nu” (Budge, 1904) or Nunu (Ashby, 1997), is the water god or god of the watery abyss, emptiness, or void at the beginning of creation, or mixture of these two; the god representation of the waters of the annual-flooded Nile.
An alternative hieroglyph for Nun is: , i.e. three pots, above the sky symbol , aka Nut, plus three wave rows, above the "Nun alter platform", plus god symbol (man seated). The Nun might derived from the term "nen", meaning "inactivity" (Budge, 1904).
Ogdoad | 8
The Nun and the Ogdoad are closely related, historically. The Ogdoad, said to be a "company of gods" (god family or paut) older than that of the the Ennead, of Heliopolis. Budge (1904) conjectures that the nine gods of the Ennead was formed via the following formula:
- Ogdoad (8) + Atum (1) = Ennead (9)
Whatever the case, Nun either predated the Ogdoad, or he was part of the Ogdoad, then later became a singular god. Most likely, Nun predated the Ogdoad.
In 520BC, Pythagoras introduced the term nous (νόος) (NE:348), secret name: eighth or eight (ογδοας) (NE:348), which he defined as the "mind of god". This later became the "noosphere", aka "sphere of mind", concept, first employed in Pierre Teilhard, in his Cosmogenesis (1922), and later adopted by Vladimir Vernadsky, and others.
Words derived from Nun (or Nu), include: new, negative, nil, non, nope, no, naught, negligible, and names such as: Noah (Christianity), or Nuh (Islam), or MaNu (Hinduism).
The following are related quotes:
- “Anatolius (De Decade, c.285) remarks that the Pythagoreans call the monad ‘nous’ and liken it to the one itself (to heni auten), the intelligible god (to noeto theo), the uncreated (to agenneto), beauty itself (autokalo), the good itself (autoagatho), and—among the virtues—the wisdom (phronesei) of the one.”
