There is one broad line of division marking all the languages and civilizations of the world--the line between the ideographic and the literal; it marks the use of hieroglyphic or of alphabetic writing, and it denotes a culture so widely different from ours, modes of thought so distinct, views of life and man’s relation to it one might almost say so opposite to ours, as to point unmistakably to a most distant past, and a former world-culture probably as wide-spread in its day as is now ours--or more so. And it is one of the strangest and most remarkable of the phenomena we are considering, that the two divisions have overlapped each other in time to such a degree that whereas we have in Sanskrit, the most perfect type of Aryan, or inflectional languages, the oldest of them all; on the other hand we have in Chinese an equally perfect linguistic medium of the other type, kept alive into our own times. When we consider the development and status of the American civilizations which have been revealed to us, and especially when we have once opened our minds to the possibility that world-civilizations different in their time from ours in ours, may for all we know have existed and been blotted out ages ago, leaving linguistic traces, and perhaps perpetuating cultural remnants in a few parts of the earth, it is impossible not to recognize the breadth of the problem we are considering. All over the American continent at the time of the Discovery we see cultures and systems whose time had come. Back of most of the North and South American tribes we find the remains of mighty and utterly extinct civilizations--only their dim memory left. In the centers of higher culture from Mexico to Peru we see the ancient civilization brought further down to our own times; but there also, in process, all the incidents of break-up and an expiring greatness. Internecine strife, invasion from outside, changes of center, are all going on, and all marked by a _steady decrease_ in everything that means civilization. Of the ancient mathematical and astronomical knowledge a corner of which is revealed to us by the Maya glyph remains, only a distorted fragment appears in the Mexican, where also hieroglyphs have yielded to a cruder rebus-writing. The stately and incomparable compositions and architecture of Palenque, Copan and Quiriguá have yielded to the ball courts and local strifes of Chichen Itza--all this following the very course of changing historical succession preserved in the Chronicles. The later the date, the lower in every case the culture; this is impossible not to recognize, nor have we traces of any different course of events. Of course we see the rise of the Aztec nation, a small cycle, but like the Gothic upon the Roman, it comes at the end of the general American break-up--an incursion of barbarians settling on and preserving for us fragments of the culture that preceded them, just as has happened over and over again all over the world. And the same with
