XXII. INVENTIONS.
Most people are sure to think that, at least in the matter of inventions, ours is the only time worth considering. The people of the Thirteenth Century, however, made many wonderful inventions and adaptations of mechanical principles, as well as many ingenious appliances. Their faculty of invention was mainly devoted to work in other departments besides that of mechanics. They were inventors of designs in architecture, in decoration, in furnishings, in textiles, and in the beautiful things of life generally. Their inventiveness in the arts and crafts was especially admirable and, indeed, has been fruitful in our time, since, with the reawakening in this matter, we have gone back to imitate their designs. Good authorities declare these to be endless in number and variety. Such mechanical inventions as were [{457}] needed for the building of their great cathedrals, their municipal buildings, abbeys, castles, piers, bridges and the like were admirably worked out. Necessity is the mother of invention, and whenever needs asserted themselves, these old generations responded to them, very successfully. There are, however, a number of inventions that would attract attention even, in the modern time for their practical usefulness and ingenuity. With the growth of the universities writing became much more common, textbooks were needed, and so paper was invented. With the increase of reading, to replace teaching by hearing, spectacles were invented. Time became more precious, clocks were greatly improved, and we hear of the invention of something like an alarm clock, an apparatus which, after a fixed number of hours, woke the monk of the abbey whose duty it was to arouse the others. Organs for churches were greatly improved, bells were perfected, and everything else in connection with the churches so well fashioned that we still use them in their Thirteenth Century forms. Gunpowder was not invented, but a great many new uses were found for it, and Roger Bacon even suggested, as I have said, that sometime explosives would enable boats to move by sea without sails or oars, or carriages to move on land without horses or men. Roger Bacon even suggested the possibility of airships, described how one might be made, the wings of which would be worked by a windlass, and thought that he could make it. His friend and pupil, Peregrinus, invented the double pivoted compass, and, as the first perpetual-motion faddist, described how he would set about making a magnetic engine that he thought would run forever. When we recall how much they accomplished mechanically in the construction of buildings, it becomes evident that any mechanical problem that these generations wanted solved they succeeded in solving very well. What they have left us as inventions are among the most useful appliances that we have. Without paper and without spectacles, the intellectual world would be in a sad case, indeed. Many of the secrets of their inventions in the arts and crafts have been lost, and, in spite of all our study, we have not succeeded in rediscovering them.
