A bolt is to be affixed to a modern door. Instead of being applied with a plate of iron or brass, in itself a decorative feature on a blank space like that of the surface of a door, the carpenter cuts a piece of wood out of the edge of the door, sinks the bolt out of sight, so that nothing shall appear to view but a tiny meaningless brass handle, and considers that he has performed a very neat job. Compare this method with that of a mediaeval locksmith, and the result with his great iron bolt, and if you can not appreciate the difference, both in principle and result, I should recommend a course of historic art study until you are convinced. On the other hand, it is not necessary to carry your artistry so far that you build a fence of nothing but cedar logs touching one another, or that you cover your entire door with a meander of wrought iron which culminates in a small bolt. Enthusiastic followers of the Arts and Crafts movement often go to morbid extremes. _Recognition_ of material and method does not connote a _display_ of method and material out of proportion to the demands of the article to be constructed. As in other forms of culture, balance and sanity are necessary, in order to produce a satisfactory result. But when a craftsman is possessed of an aesthetic instinct and faculty, he merits the congratulations offered to the students of Birmingham by William Morris, when he told them that they were among the happiest people in all civilization--"persons whose necessary daily work is inseparable from their greatest pleasure." A mediaeval artist was usually a craftsman as well. He was not content with furnishing designs alone, and then handing them over to men whose hands were trained to their execution, but he took his own designs and carried them out. Thus, the designer adapted his drawing to the demands of his material and the craftsman was necessarily in sympathy with the design since it was his own. The result was a harmony of intention and execution which is often lacking when two men of differing tastes produce one object. Luebke sums up the talents of a mediaeval artist as follows: "A painter could produce panels with coats of arms for the military men of noble birth, and devotional panels with an image of a saint or a conventionalized scene from Scripture for that noble's wife. With the same brush and on a larger panel he could produce a larger sacred picture for the convent round the corner, and with finer pencil and more delicate touch he could paint the vellum leaves of a missal;" and so on. If an artistic earthenware platter was to be made, the painter turned to his potter's wheel and to his kiln. If a filigree coronet was wanted, he took up his tools for metal and jewelry work.
