Fo-hi

The first Emperor of China, Fo-hi, was produced supernaturally from a rainbow.  He appeared in the country after a convulsion in which waters in the bosom of the earth burst forth and overflowed it. He was attended by his wife and three sons and three daughters by whose intermarriage the whole "circle of the earth" was inhabited. This catastrophe occurred because man despised the Supreme Monarch of the Universe.

Fo-hi was credited with the invention of music, dressmaking, and a symbolic mode of writing.  He also introduced the custom of sacrificing at the solstices (having bred seven sorts of animals for that purpose).
