Of iron-mongery of Dante's time, the author of the Thirteenth the Greatest of Centuries writes as follows: "It is difficult to understand how one of the village blacksmiths of the time made a handsome gate that has been the constant admiration of posterity ever since, or designed high hinges for doors that artists delight to copy, or locks and latches and bolts that are transported to our museums to be looked at with interest not only because they are antiques but for the wonderful combination of the beautiful and the useful which they illustrate. The surprise grows the greater when we realize that these beautiful objects were made not only in one place or even in a few places, but in nearly every town of any size in England, France, Italy, Germany and Spain at various times during the thirteenth century and that at any time a town of considerably less than ten thousand inhabitants seemed to be able to obtain among its own inhabitants, men who could make such works of art not as copies nor in servile imitation of others, but with original ideas of their own, and make them in such perfection that in many cases they have remained the models for many centuries." That is especially true of the thirteenth century glass windows as seen, for example, in the Cathedrals of York, Lincoln, Westminster, Canterbury, Chartres, Rheims, and in Notre Dame and the Sainte Chapelle, Paris. Modern art with all its boasting cannot begin to make anything comparable to that antique glass made and put in place by faith and love long before Columbus discovered America. There are tiny bits of it in this country as a result of the relic hunting of our soldiers in the World's War. Many of them got a fragment of the shattered glass of Rheims, "petrified color" deep sky blue, ruby, golden green, and sent it home to a sweetheart, a wife or sister to be mounted on a ring or set in a pin. The donors for the most part of the glass of the thirteenth century Cathedrals, were guilds at that time. For the Cathedral of Chartres e.g. the drapers and the furriers gave five windows, the porters one, the tavern-keepers two, the bakers two. In Dante's time glass-making reached its climax and then the curve began to decline, until in the eighteenth century and in the early part of the nineteenth century glass-making reached its lowest point. Great as was Dante's day in the efficiency and education promoted by the Guild system--Dante himself was a member of it--the achievement of his era in architecture was the "most notable perhaps because what happened there epitomizes all that was done elsewhere and the nature of what was accomplished is precisely that which informed the whole body of medieval achievement." (The Substance of Gothic, p. 137.)
