Goddess Culture

Not a definitive list by any means but if you have no place to start and want to learn try these:

When God Was a Woman by Merlin Stone

The Great Cosmic Mother by Monica Sjoo and Barbara Mor

The Great Goddess by Jean Markale

The Chalice and the Blade by Riane Eisler

Sacred Pleasure by Riane Eisler

The Language of the Goddess by Marija Gimbutas

The Goddess Companion by Patricia Monaghan

Feel free to add to the list. I'll keep track and compile a bibliography that I'll post on my blog.
