Quid est secretum? Visual Representation of Secrets in Early Modern Europe, 1500–1700 is the companion volume to Intersections 65.1, Quid est sacramentum? Visual Representation of Sacred Mysteries in Early Modern Europe, 1400–1700. Whereas the latter volume focused on sacramental mysteries, the current one examines a wider range of secret subjects. The book examines how secret knowledge was represented visually in ways that both revealed and concealed the true nature of that knowledge, giving and yet impeding access to it. In the early modern period, the discursive and symbolical sites for the representation of secrets were closely related to epistemic changes that transformed conceptions of the transmissibility of knowledge.
