The Printing Press
He who first shortened the labor of copyists by device of movable types was disbanding hired armies, and cashiering most kings and senates, and creating a whole new democratic world: he had invented the art of printing.
The Renaissance spread to Germany, France, England, and Spain in the late fifteenth and the sixteenth centuries. In its migration northward, Renaissance culture adapted itself to conditions unknown in Italy, such as the growth of the monarchical state and the strength of lay piety. In England France, and Spain, Renaissance culture tended to be court-centered and hence anti-republican. In Germany, no monarchical state existed but a vital tradition of lay piety was present in the Low Countries. The Brethren of the Common Life, for example, was a lay movement emphasizing education and practical piety. Intensely Christian and at the same time anticlerical (shades of what was to come!), the people in such movements found in Renaissance culture the tools for sharpening their wits against the clergy -- not to undermine faith, but restore its ancient apostolic purity.
