Anthropologists and historians have shown us that 'male' and 'female' are variously defined historically and cross-culturally. The contributions to this volume focus on the voluntary and involuntary, temporary or permanent transformation of gender identity. Overall, this volume provides powerful and compelling illustrations of how, across a wide range of cultures, processes of gender transformation are shaped within, and ultimately constrained by, social and political context. From medical responses to biological ambiguity, legal responses to cases brought by transsexuals, the historical role of the eunuch in Byzantium, the social transformation of gender in Northern Albania and in the Southern Philippines, to North American 'drag' shows, English pantomime and Japanese kabuki theatre, this volume offers revealing insights into the ambiguities and limitations of gender transformation.
