Lyombe Eko carries out an historical and cultural survey of the regulation of visual depictions of explicit human sexual conduct from their earliest appearance on the clay tablets of the valley of the Tigris and Euphrates rivers in ancient Mesopotamia, to the tablet computers of Silicon Valley. The Regulation of Sex-Themed Visual Imagery analyzes the contemporary problem of the applicability of the human right of freedom of expression to explicit imagery in the face of societal interests in the regulation of representations of human sexuality. This book will be of interest to scholars, students, and broad audiences interested in comparative studies in pornography regulation, the history of pornography, the law of pornography and obscenity, and visual culture and history alike.
