The medieval architects and builders knew nothing of these classical architectural refinements. They learned for themselves by actual experience the necessity for making such optical [{132}] corrections and then introduced them so carefully, that it is not until the last decade or so that their presence has been realized. It is only by an educational tradition of the greatest value that the use of such a refinement could become as general as Professor Goodyear has found it to be. Besides the practical work then, and the actual exercise of craftsmanship and of design which the apprentices obtained from the guild, there was evidently a body of very definite technical information conveyed to them, or at least to certain chosen spirits among them, which carried on precious traditions from place to place. This same state of affairs must of course have existed with regard to stained glass work, the making of bells and especially the finer work in the precious metals. Practical metallurgy must have been studied quite as faithfully as in any modern technical school, at least so far as its practical purposes and application were concerned. Here we have the secret of the technical schools revealed.
It is extremely interesting to study the details of the very practical organization by which this great educational movement in the arts and crafts was brought about. It was due entirely to the trades' and merchants' guilds of the time. In the cathedral towns the trades' guilds preponderated in influence. There gathered around each of these cathedrals during the years when work was most active, numbers of workmen engaged at various occupations requiring mechanical skill and long practice at their trade. These workmen were all affiliated with one another and they were gradually organized into trades' unions that had a certain independent existence. There was the guild of the stone workers; the guild of the metal workers—in some places divided into a guild of iron workers and a guild of gold workers, or workers in precious metals; there was the guild of the wood workers and then of the various other forms of occupation connected with the supplying of finished or unfinished materials for the cathedral. In association with these were established guilds of tailors, bakers, butchers, all affiliated in a merchants' guild which maintained the rights of its members as well as the artisans' guilds. Some idea of the number and variety of these can be obtained from the list given in the chapter on the Origin of the Drama.

These were the workmen who not only accomplished such brilliant results in art work, but also succeeded in training other workmen so admirably for every line of artistic endeavor.
It is somewhat difficult to understand just how a village carpenter did wood-carving of so exquisite a design and such artistic finish of detail that it has remained a subject of admiration for centuries. It is quite as 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 huge 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. We are assured, however, by the Rev. Augustus Jessopp, that he has seen in the archives of the old English parishes, some of the receipts for the bills of these village workmen as we would term them, for the making of these beautiful specimens of arts and crafts.
