The 10 essays here are the result of a conference devoted to the study of medieval technology in April 1995. Taken together, they aim to help dispel the common misconception that medieval people somehow had to toil in a world bereft of technical innovation and ingenuity. The authors of the papers, all experts in their fields, show the Middle Ages not only to be a time of considerable technological development, but also the ways in which the technologies of building construction, manufacture and metallurgy were shaped by broader forces of culture, social identity, political ambition and the local environment.
