The Myth of Matriarchal Prehistory: Why An Invented Past Will Not Give Women a Future is a book by Cynthia Eller that seeks to deconstruct the theory of a prehistoric matriarchy. This hypothesis, she says, developed in 19th century scholarship and was taken up by 1970s second-wave feminism following Marija Gimbutas. Eller, a professor of religious studies at Claremont Graduate University, argues in the book that this theory is mistaken and its continued defence is harmful to the feminist agenda.
