Sphinx is the corrupt Greek word and not the symbol or name for this "African" artifact.
There is a greek stature of a woman with breasts this "is" the sphinx. Greek men thought females were evil. They felt the most perfect love was love of a man. Hence their acceptance of homosexuality [i.e. Alexander the Great].
She "the fable goes" stood on a cliff and asked everyone who passed a riddle:
What crawls in the morning on all four; walks in the afternoon on two legs; and then walks on three legs in the evening?
Wrong answers got a strangle and push over the cliff. The greek word "Sphinx" means to hold/to strangle.
Odeipus solved the riddle: man as an infant, adult and elder. He then returned to his village--killed his father and married his mother. Sigmund Freud erroneously used this backwards analogy in his Odeipus Complex Theory [i.e. desire of a male for his mother].
The African Harmachis is the son of God who sits as a lion with a man's head. The concept is on a higher level of consciousness, according to Anthony Browder -- man's ability to control his animal instincts.
