Amazon.com description: Product Description: This first paperback facsimile of the classic 1913 edition includes thirteen photographs and numerous illustrations of the great cathedrals of Northern France. Henry Adams referred to this book as A Study of Thirteenth-Century Unity, and its expansive scope, together with the author's deep understanding of the period, makes it a classic in art history as well as in American literature. He wrote, I wanted to show the intensity of the vital energy of a given time, and of course that intensity had to be stated in its two highest terms-religion and art. Henry Adams' record of his journeys through France, searching for images of unity in an age of conflict, is accompanied by observations on literature, politics, religion, and maior church leaders such as Abelard, St. Francis of Assisi, and St. Thomas Aquinas.
