The study of the creation of canine breeds in early modern Europe, especially Spain, illustrates the different constructs against which notions of human identity were forged. This book is the first comprehensive history of early modern Spanish dogs and it evaluates how two of Spain's most celebrated and canonical cultural figures of this period, the artist Diego Velázquez and the author Miguel de Cervantes, radically question humankind's sixteenth-century anthropocentric self-fashioning. In general, this study illuminates how Animal Studies can offer new perspectives to understanding Hispanism, giving readers a fresh approach to the historical, literary and artistic complexity of early modern Spain.
