Professor Draper’s philosophy of history is, indeed, something to make one pause. He says on page 291, “The result of the Crusades had shaken the faith of all Christendom.” As a matter of easily ascertainable history, the faith of Christendom was never so strong as during the century immediately following the Crusades. This was the thirteenth century, with the glorious Gothic cathedrals; the great Latin hymns; the magnificent musical development; the wondrous tribute of painting to religion, from Cimabue and Duccio to Giotto and Orcagna, and of sculpture from the Pisani to the great designers of some of the doors of the baptistry of Florence, of the finest arts and crafts in gold and silver, in woodwork, in needle-work, in illuminated books–all precious tributes to religious belief. In the hundred years after the Crusades, the Popes secured a position of influence in Europe greater than they had ever had before or have ever enjoyed since, which they used to secure the foundation of hospitals everywhere throughout Europe, the establishment of universities, the organization of religious orders for teaching and nursing purposes, and the finest development of social life and social happiness that the world had ever known.
