This engaging study introduces the reader to one of the greatest achievements of Western art: the climactic phase of Gothic architecture in the first half of the thirteenth century. Through a comparative analysis of the cathedrals of Chartres, Reims, and Amiens, the author illuminates the technical, theological, artistic, and social factors that formed the High Gothic synthesis. Drawing on a lifetime of scholarship, he successively characterizes the different parts of the Gothic cathedral and describes the human context of the three great buildings.
