Ancient archeology and anthropology is all based in educated speculation. The conclusion that early civilizations were peaceful and goddess-worshipping comes through an interdisciplinary method, not based in the Minoans alone. Besides the fact that it seems perfectly obvious that the source of life for humans would reflect a deity that was the source of life of the universe, there’s this description of the systems science that Eisler used to come to the conclusions she reached in The Chalice and the Blade:

Drawing from a trans-disciplinary database, it applies this approach to a wide-ranging exploration of how humans think, feel, and behave individually and in groups. Its sources include cross-cultural anthropological and sociological surveys,[3] and studies of individual societies[4] as well as writings by historians, analyses of laws, moral codes, art, literature, scholarship from psychology, economics, education, political science, philosophy, religious studies, archaeology, the study of myths and legends; and data from more recent fields such as primatology, neuroscience, chaos theory, systems self-organizing theory, non-linear dynamics, gender studies, women’s studies, and men’s studies.[5]

Many, many others have reached the same conclusions. I said that the statues may well have been used as hunting luck charms, but doesn’t it make sense that you’d take your most revered ancestor, your Clan Mother, along for help in ensuring a good hunt? It does to me.

You are correct that the number of statues is closer to 200 and that part of that quote was incorrect, but I don’t believe that the rest of it was.
