“I wonder how anyone determined that that is a woman”
I agree. Some bookwork of an antropologist just failed another ink block test. and there are two of them that just do not look anything like a woman. Therefore they must be twin sisters.
It always about sex as even today it’s an enigma when trying to explain it.
Phallic along with woman’s reproduction and nurturing capabilities besides umbilical marks never cease to amaze.
It’s not a big leap in art work or psychology.
