How has female homosexuality been approached throughout the ages? Is it possible to establish a temporal continuity in the way homoeroticism (and homosociability) among women was experienced and perceived? Are the categories of sexual orientation and erotic identity valid and universal for its historical understanding? Lesbohistory has deeply explored and enriched these topics and debates, pointing out the anachronisms and distortions involved in postulating an inherent homosexual identity to the human condition and a transhistorical “lesbian personality.” From this same perspective, this book offers a comprehensive synthesis of female homosexuality in the West, beginning in Greco-Roman antiquity, continuing through the medieval, modern, and contemporary periods, and concluding in the present. Its purpose, through diverse sources, practices, representations, discourses, and testimonies, is to account for both historical continuities and similarities—starting with the rejection and invisibility of female homoerotic relationships, as they displaced male power or challenged the patriarchal order—as well as historical differences—also in relation to male homosexuality—constituting a valuable contribution to the still scarce studies dedicated to lesbohistory in the Spanish-speaking world to date.
