Sex, Identity and Hermaphrodites in Iberia, 1500–1800 [EPUB ebook] 

Early modern European thought held that men and women were essentially the same. During the seventeenth century, medical and legal arguments began to turn against this ‘one-sex’ model, with hermaphroditism seen as a medieval superstition. This book traces this change in Iberia in comparison to the earlier shift in thought in northern Europe.
