Some of the locks and keys and latches and hinges for doors made during this period are among the most beautiful examples of iron work in the world. The Cluny Museum in Paris possesses a number of these as well as other iron work of Columbus' Century which show that the men of this time had the true artistic spirit in their work. The armorers of the period made probably the most beautiful armor that has ever been made, and the finest pieces in collections, especially {113} in national armories, are nearly all from this time. Scent boxes and jewel boxes of various kinds in the precious or semi-precious metals were always executed with fine artistic taste, or at least some of the best examples of these in the world come from this time. Clocks were made with a perfection of mechanism and at the same time an ornateness that give them a place in the art world instead of merely in the industrial domain. The furniture of the time is noted for its artistic quality, and some of the smaller pieces made by well-known sculptors or under their direction were works of art that now are thought of as world treasures for all time. [Illustration: CLOCK (FIFTEENTH CENTURY, PARIS)] {114} CHAPTER VIII THE ARCHITECTURE OF THE CENTURY Just as the introduction of Greek ideas gave a new impetus to literature and art and sculpture and painting, so it did also, and perhaps to an even greater degree, to architecture. The effect of classic thought had begun to be felt before 1450. It was noted first in ecclesiastical architecture and its influence can be traced throughout Europe. Brunelleschi, who built the great dome of the Cathedral in Florence, died in 1444, but not until he had shown the world of his time how beautiful such a conception was and how it could be accomplished. He had gone to Rome and studied the Pantheon, as well as all the other great buildings which the Romans had left in that city, and during his studies, becoming enamored of the subject, he mastered every detail of their style and became familiar with every form of Roman art. He first completed the Church of San Lorenzo in Florence and then was entrusted with a larger work, the completion of the Santo Spirito, which Arnolfo and Giotto had left unfinished and apparently, according to the practice of the Middle Ages, without even a drawing to show how they intended to complete it. They would have given it a Gothic roof. Brunelleschi conceived the dome and then, in the course of his studies and designing, definitely initiated the development of Renaissance architecture.
