influence of long-continued and bloody conflicts, civil and foreign, by which the more warlike rather than the more highly cultured nations had been brought into prominence and power. But this anterior and superior civilization, resting largely as it does on vague tradition, and preserved to our knowledge in general allusions rather than in detail, may, like the native condition since the conquest, be utilized to the best advantage here as illustrative of the later and better-known, if somewhat inferior civilization of the sixteenth century, described by the conqueror, the missionary, and the Spanish historian.
Antique remains of native skill, which have been preserved for our examination, may also be largely used in illustration of more modern art, whose products have disappeared. These relics of the past are also of the highest value as confirming the truth of the reports made by Spanish writers, very many, or perhaps most, of whose statements respecting the wonderful phenomena of the New World, without this incontrovertible material proof, would find few believers among the sceptical students of the present day. These remains of antiquity, however, being fully described in another volume of this work, may be referred to in very general terms for present purposes.
Of civilization in general, the nature of its phenomena, the causes and processes by which it is evolved from savagism, I have spoken sufficiently in the foregoing chapter. As for the many theories respecting the American civilization in particular, its origin and growth, it is not my purpose to discuss them in this volume. No theory on these questions could be of any practical value in the elucidation of the subject, save one that should stand out among the rest so preëminently well-founded as to be generally accepted among scientific men, and no one of all the multitude proposed has acquired any such preëminence. A complete résumé of all the theories on the subject, with the foundations which support them, is given else-
