“This word has also hardly changed in centuries. The earliest goddess of the Stellar period, of the primordial abyss and night sky, called Nun. She was the great virgin.
She was also associated with the fish, (Nun means fish). This refers to the Vesica Piscis, the symbol of the great Creatrix.
So today we have the “Nuns of Christ” who are also known as the chaste “Brides of Christ.” We also derive our word noon from Nun. Noon was never 12 midday, but 12 midnight, when the goddess was seen above in the night sky. The nocturnal dome was her great womb and the planets and stars were seen as the inseminating spermatozoon’s or seeds with her.
The sun too was seen this way. It was the “seed” of God entering her womb or ovum every morning, resulting in life and fruition and abundance.
It is for the same reason why it became customary to light great fireworks on special zodiacal days, to represent the seeds of light being planted in the celestial womb for a bright tomorrow.”
