Book excerpt: An innovative volume of fifteen interdisciplinary essays at the nexus of material culture, performance studies, and game theory, Playthings in Early Modernity emphasizes the rules of the game(s) as well as the breaking of those rules. Thus, the titular "plaything" is understood as both an object and a person, and play, in the early modern world, is treated not merely as a pastime, a leisurely pursuit, but as a pivotal part of daily life, a strategic psychosocial endeavor.
