You might find some similarity between them and Erichtonius (
http://www.pantheon.org/articles/e/erechtheus.html) of Athens in their serpentine legs. And they suffered Deluge as Deucalion
or Noah, created human race and Art of Fortune Telling after that in Legend
(Read about I-tuang as sacred book both for Confucians and Taoists). Then
they turned to First Rulers of China. (Han Dynasty, Wall Picture).
(Left) In Legend, Fu Xi first found Eightfolded Divinatory Signs hinted
from the shape of lizard, later fortune telling art from it compiled as
I-tuang, sacred text both for Confucians and Taoists. (Han Dynasty, Engrave
of Sarcophagus).
The couple, Fu Xi and Nu Gua below are depicted as truly Sacred Entity
who holds Sun and Moon. But in some folktales, they are reduced to merely
human figure and brother and sister, turned into first ancestor of humanity
after great deluge, as Deucalion and Pyrrha of Greek Myth. They hold compass
and square as symbol of cultural heroes. (Han Dynasty Engrave)
Fu Xi, depicted as Serpentine Body god has many aspect. His wife, Nu Gua
was independent entity in older cycle of mythology. She created humanity
from mud and mended Sky Dome when evil god of water crashed Northwest Pole
and destroyed it. (that was why generally China slopes toward east. (Left
