"This collection establishes that efforts to produce scientific explanations for same-sex desires and sexual behaviours are not a modern invention, but have long been characteristic of European thought. The sciences of antiquity had posited various types of same-sexual affinities rooted in singular natures. These concepts were renewed, elaborated, and reassessed from the late medieval scientific revival to the early Enlightenment. The deviance of such persons seemed outwardly inscribed upon their bodies, documented in treatises and case studies. It was attributed to diverse inborn causes such as distinctive anatomies or physiologies, and embryological, astrological, or temperamental factors" (publisher).
