Utilizing the records of several Venetian courts that dealt with sex crimes, Ruggiero traces the evolution of both licit and illicit sexuality during the 14th and 15th centuries. He argues that the use of such records reveals not only the nature of sexual behaviour that was considered criminal, but also what society established as the norm. Through this examination of illicit sexuality, Ruggiero sheds light on the institutions, languages, social life and values not only of this shadow-culture, but also of Venetian society and, ultimately, the Renaissance itself.
