In this book, Eisler traces tensions between these two models, starting in prehistory. It draws from many sources, including the study of myth and
linguistics as well as archeological findings by the Indo-Europeanists
J. P. Mallory and
Marija Gimbutas and archeologists such as
James Mellaart,
Alexander Marshack,
Andre Leroi-Gourhan, and
Nikolas Platon. Based on these findings, Eisler presents evidence how for the longest span of prehistory, cultures in the more fertile regions of the globe oriented primarily to the partnership model, which Eisler also calls a "gylany", a neologism for a society in which relationships between the sexes are an egalitarian partnership. This gender partnership was a core component of a more egalitarian, peaceful, and matrifocal culture with a focus on life-giving, centering on nurture. These societies once were widespread in Europe around the Mediterranean, and lasted well into the
early Bronze Age in the
Minoan civilization of
Crete. Later, culture skewed towards Patriarchy during a chaotic time of upheaval related to climate change and incursions of warlike, nomadic tribes. These peoples brought with them a domination system and imposed rigid rankings of domination, including the rigid domination by men of women and the equation of "real masculinity" with power and violence. This led to radical cultural transformation. Eisler's book is not the only work describing this massive cultural shift. Other scholars have paid special attention to a radical change in gender relations. Historian
Gerda Lerner details it in her Oxford University book
The Creation of Patriarchy. However, Eisler does not use the term "
patriarchy." Nor does she use "
matriarchy" to describe a more gender-balanced society, noting rule by fathers (patriarchy) and rule by mothers (matriarchy) can be two sides of a dominator coin. She proposed the real alternative is a partnership system or
gylany. Nonetheless, some critics have accused Eisler of writing about a "matriarchy" in prehistoric times. According to them, she claims earlier societies where women were not subordinate were ideal. Eisler does point out how more partnership-oriented societies described in
The Chalice and the Blade were more peaceful and generally equitable; yet, she emphasizes they were not ideal. She further makes it clear the point is not returning to any "
utopia" but rather using what we learn from our past to move forward to a more equitable and sustainable future. Some archaeologists also question these earlier societies were more peaceful, especially critiques of Marija Gimbutas, one of Eisler's sources. This critique fits the conventional narrative of cultural evolution as a linear progression from "
barbarism" to "
civilization"—a narrative Eisler challenges in light of the brutality of "civilizations" ranging from Chinese, Indian, Arab, and European empires to
Nazi Germany and
Stalin's Soviet Union. In addition, some archaeologists question whether the great profusion in these earlier cultures of female figurines, going back 30,000 years and perhaps even longer, indicates that they venerated a
Goddess or
Great Mother. When these figurines were first excavated in the 19th century, the men who found them in millennia-old caves called them
Venus figurines (a term still used today). ==Subsequent confirmation==
