To reconstruct the sexual and cultural history of Tiresias, the author examines a wide range of technological, medical, and sexual discourses. The strangely hybrid body of Tiresias--offers an index of the proliferating discourses of sexual identity, especially as voice or performance can be read as a symptom of sexual deviance. Tracing the intersections of sexual difference, this book explores not only the cultural history of a sexual myth, but also the cultural representations of homosexuality, illuminating the persistent sexological images of homosexuality as gender inversion.
