At first the only people encountered by the Spaniards in America were savages of a Mongoloid type. Many of these savages were cannibals. It is a misfortune for science that the first Europeans to reach America were these rather incurious Spaniards, without any scientific passion, thirsty for gold, and full of the blind bigotry of a recent religious war. They made few intelligent observations of the native methods and ideas of these primordial people. They slaughtered them, they robbed them, they enslaved them, and baptized them; but they made small note of the customs and motives that changed and vanished under their assault. They were as destructive and reckless as the British in Tasmania, who shot the last Palæolithic men at sight, and put out poisoned meat for them to find.
Great areas of the American interior were prairie land, whose nomadic tribes subsisted upon vast herds of the now practically extinct bison. In their manner of life, in their painted garments and their free use of paint, in their general physical characters, these prairie Indians showed remarkable resemblances to the Later Palæolithic men of the Solutrian age in Europe. But they had no horses. They seem to have made no very great advance from that primordial state, which was probably the state in which their ancestors had reached America. They had, however, a knowledge of metals, and most notably a free use of native copper, but no knowledge of iron. As the Spaniards penetrated into the continent, they found and they attacked, plundered, and destroyed two separate civilized systems that had developed in America, perhaps quite independently of the civilized systems of the old world. One of them was the Aztec civilization of Mexico; the other, that of Peru. They had arisen out of the heliolithic sub-civilization that had drifted across the Pacific from its region of origin round and about the Mediterranean. We have already noted one or two points of interest in these unique developments. Along their own lines these civilized peoples had reached to a state of affairs roughly parallel with the culture of pre-dynastic Egypt or the early Sumerian cities. Before the Aztecs and the Peruvians there had been still earlier civilized beginnings which had either been destroyed by their successors, or which had failed and relapsed of their own accord.
