Nick, I post something here, we will deepen the rest of the issue in our beautiful mail exchange
Marija Gimbutas' Goddesses and Gods of Old Europe is a dated book (1974)
She revised many of her theories 15 years later, in her
work "The Language of the Goddess" (1989).
The cave painting from La Pasiega, Santander, here is dated 15.000-13.000 b.C., and is described as "horned
serpent", as "symbol of embodied energy and stimulator of the process of becoming". (pag.277-280).
In the same
work Gimbutas reads the
jar lid figure posted on reply#34 of this discussion as an owl-shaped
head, not
bull.
It is described as a depiction of the prehistoric bird-goddess.
I attach a pic from page 53, where the the authoress illustrates the evolution of this iconography, from 5200 to 4500 b.C.
Best
Nico
