2. PREHISTORIC PEOPLES
THE PREHISTORIC PERIOD
In studying the historic period our chief concern is with those peoples whose ideas or whose deeds have aided human progress and the spread of civilization. Six-sevenths of the earth's inhabitants now belong to civilized countries, and these countries include the best and largest regions of the globe. At the beginning of historic times, however, civilization was confined within a narrow area—the river valleys of western Asia and Egypt. The uncounted centuries before the dawn of history make up the prehistoric period, when savagery and barbarism prevailed throughout the world. Our knowledge of it is derived from the examination of the objects found in caves, refuse mounds, graves, and other sites. Various European countries, including England, France, Denmark, Switzerland, and Italy, are particularly rich in prehistoric remains.

THE TWO AGES
The prehistoric period is commonly divided, according to the character of the materials used for tools and weapons, into the Age of Stone and the Age of Metals. The one is the age of savagery; the other is the age of barbarism or semicivilization.
THE STONE AGE
Man's earliest implements were those that lay ready to his hand. A branch from a tree served as a spear; a thick stick in his strong arms became a powerful club. Later, perhaps, came the use of a hard stone such as flint, which could be chipped into the forms of arrowheads, axes, and spear tips. The first stone implements were so rude in shape that it is difficult to believe them of human workmanship. They may have been made several hundred thousand years ago. After countless centuries of slow advance, savages learned to fasten wooden handles to their stone tools and weapons and also to use such materials as jade and granite, which could be ground and polished into a variety of forms. Stone implements continued to be made during the greater part of the prehistoric period. Every region of the world has had a Stone Age. [1] Its length is reckoned, not by centuries, but by milleniums.

THE AGE OF METALS
The Age of Metals, compared with its predecessor, covers a brief expanse of time. The use of metals came in not much before the dawn of history. The earliest civilized peoples, the Babylonians and Egyptians, when we first become acquainted with them, appear to be passing from the use of stone implements to those of metal.
COPPER
Copper was the first metal in common use. The credit for the invention of copper tools seems to belong to the Egyptians. At a very early date they were working the copper mines on the peninsula of Sinai. The Babylonians probably obtained their copper from the same region. Another source of this metal was the island of Cyprus in the eastern Mediterranean. The Greek name of the island means "copper."
BRONZE
But copper tools were soft and would not keep an edge. Some ancient smith, more ingenious than his fellows, discovered that the addition of a small part of tin to the copper produced a new metal—bronze—harder than the old, yet capable of being molded into a variety of forms. At least as early as 3000 B.C. we find bronze taking the place of copper in both Egypt and Babylonia. Somewhat later bronze was introduced into the island of Crete, then along the eastern coast of Greece, and afterwards into other European countries.
IRON
The introduction of iron occurred in comparatively recent times. At first it was a scarce, and therefore a very precious, metal. The Egyptians seem to have made little use of iron before 1500 B.C. They called it "the metal of heaven," as if they obtained it from meteorites. In the Greek Homeric poems, composed about 900 B.C. or later, we find iron considered so valuable that a lump of it is one of the chief prizes at athletic games. In the first five books of the Bible iron is mentioned only thirteen times, though copper and bronze are referred to forty-four times. Iron is more difficult to work than either copper or bronze, but it is vastly superior to those metals in hardness and durability. Hence it gradually displaced them throughout the greater part of the Old World. [2]
FIRST STEPS TOWARD CIVILIZATION
During the prehistoric period early man came to be widely scattered throughout the world. Here and there, slowly, and with utmost difficulty, he began to take the first steps toward civilization. The tools and weapons which he left behind him afford some evidence of his advance. We may now single out some of his other great achievements and follow their development to the dawn of history.
