From medieval to modern, exploring instrumental attitudes toward physical gadgets, diagrams, concepts, methods, and disciplines.

Opening up the instrumental condition of the human for critical reflection and renewal, Instrumentality illuminates key moments in the intellectual history of the European Middle Ages. J. Allan Mitchell reveals how, in the predigital past, we can recognise many of the operative technics, analytics, and metaphorics that continue to shape human sense and cognition today.

Exploring the diverse modalities of medieval instruments, Mitchell's case studies encompass techniques as seemingly distinct as time-keeping mechanisms, mathematical diagrams, logical syllogisms, and the literary devices of Geoffrey Chaucer and John Gower. A cultural and intellectual history, Mitchell's work leads readers from three-dimensional objects (physical mechanisms) to two-dimensional inscriptions (maps and diagrams) and onward to overarching disciplinary norms in the early liberal and mechanical arts. Prying loose the subtle, adaptable, and generative concept of technical objects from limiting contemporary frameworks, he shows how these instruments are indispensable to the past and the future of the arts and culture at large.
