The artistic taste in dress has always accompanied the development of the useful, although dress has always been used more or less for ornament, and taste has changed by slow degrees. The primitive races everywhere delighted in bright colors, and in most instances these border on the grotesque in arrangement and combination. But many people not far advanced in barbarism have colors artistically arranged and dress with considerable skill. Ornaments change in the progress of civilization from coarse, ungainly shells, pieces of wood, or bits of metal, to more finely wrought articles of gold and silver.
Primitive Shelters and Houses.—The shelters of primitive man were more or less temporary, for wherever he happened to be in his migrations he sought shelter from storm or cold in the way most adaptable to his circumstances. There was in this connection, also, the precaution taken to protect against predatory animals and wild men. As his stay in a given territory became more permanent, the home or shelter gradually grew more permanent. So far as we can ascertain, man has always been known to build some sort of shelter. As apes build their shelters in trees, birds build their nests, and beavers dam water to make their homes, it is impossible to suppose that man, with superior intelligence, was ever simple enough to continue long without some sort of shelter constructed with his own hands. At first the shelter of trees, rocks, and caves served his purpose wherever available. Subsequently, when he had learned to build houses, their structure was usually dependent more upon environment than upon his inventive genius. Whether he built a platform house or nest in a tree, or provided a temporary brush shelter, or bark hut, or stone or adobe building, depended a good deal upon the material at hand and the necessity of protection. The main thing was to protect against cold or storm, wild animals, and, eventually, wild men.
The progress in architecture among the nations of ancient civilization was quite rapid. Massive structures were built for capacity and strength, which the natives soon learned to decorate within and without. The buildings were made of large blocks of hewn stone, fitted together mechanically by the means of cement, which made secure foundations for ages. When in the course of time the arch was discovered, it alone became a power to advance the progress of architecture. We have seen pass before our eyes a sudden transition in dwelling houses.
The first inhabitants of some parts of the Western prairies dwelt in tents. These were next exchanged for the "dugout," and this for a rude hut. Subsequently the rude hut was made into a barn or pig-pen, and a respectable farmhouse was built; and finally this, too, has been replaced by a house of modern style and conveniences. If we could consider this change to have extended over thousands of years, from the first shelter of man to the finished modern building, it would be a picture of the progress of man in the art of building. In this slow process man struggled without means and with crude notions of life in every form. The aim, first, was for protection, then comfort and durability, and finally for beauty. The artistic in building has kept pace with other forms of civilization evinced in other ways.
One of the most interesting exhibits of house-building for protection is found in the cliff dwellings, whose ruins are to be seen in Arizona and New Mexico. Tradition and other evidences point to the conclusion that certain tribes had developed a state of civilization as high as a middle period of barbarism, on the plains, where they had made a beginning of systematic agriculture, and that they were afterward driven out by wilder tribes and withdrew, seeking the cliffs for protection. There they built under the projecting cliffs the large communal houses, where they dwelt for a long period of time. Subsequently their descendants went into the valleys and developed the Pueblo villages, with their large communal houses of adobe.
Discovery and Use of Metals.—It is not known just when the human race first discovered and used any one of the metals now known to commerce and industry, but it can be assumed that their discovery occurred at a very early period and their use followed quickly. Reasoning back from the nature and condition of the wild tribes of to-day, who are curiously attracted by bright colors, whether in metals or beads or clothing, and realizing how universally they used the minerals and plants for coloring, it would be safe to assume that the satisfaction of the curiosity of primitive man led to the discovery of bright metals at a very early time. Pieces of copper, gold, and iron would easily have been found in a free state in metal-bearing soil, and treasured as articles of value. Copper undoubtedly was used by the American Indians, and probably by the inhabitants of Europe during the Neolithic Age—it being found in a native state in sufficient quantities to be hammered into implements.
Thus copper has been found in large pieces in its native state, not only in Europe but in Mexico and other parts of North America, particularly in the Lake Superior region; but as the soft hematite iron was found in larger quantities in a free state, it would seem that the use of iron in a small degree must have occurred at about the same time, or perhaps a little later. The process of smelting must have been suggested by the action of fire built on or near ore beds, where a crude process of accidental smelting took place. Combined with tin ore, the copper was made into bronze in Peru and Mexico at the time of the discovery. In Europe there are abundant remains to show the early use of metals. Probably copper and tin were in use before iron, although iron may have been discovered first. There are numerous tin mines in Asia and copper mines in Cyprus. At first, metals were probably worked while cold through hammering, the softest metals doubtless being used before others.
It is difficult to tell how smelting was discovered, although the making and use of bronze implements is an indication of the first process of smelting ores and combining metals. When tin was first discovered is not known, but we know that bronze implements made from an alloy of copper, tin, and usually other metals were used by the Greeks and other Aryan peoples in the early historic period, about six thousand years ago. In Egypt and Babylon many of the inscriptions make mention of the use of iron as well as bronze, although the extended use of the former must have come about some time after the latter. At first all war instruments were stone and wood and later bronze, which were largely replaced by iron at a still later period. The making of spears, swords, pikes, battle-axes, and other implements of war had much to do with the development of ingenious work in metals. The final perfection of metal work could only be attained by the manufacture of finely treated steel. Probably the tempering of steel began at the time iron came prominently into use.
Other metals, such as silver, quicksilver, gold, and lead, came into common use in the early stages of civilization, all of which added greatly to the arts and industries. Nearly all of the metals were used for money at various times. The aids to trade and commerce which these metals gave on account of their universal use and constant measure of value cannot be overestimated.
