It is more difficult to justify the restriction which will be imposed in the following chapters on the word Ancient. This term is used even more vaguely and variously than the other. If generally it connotes the converse of "Modern," in some connections and particularly in the study of history the Modern is not usually understood to begin where the Ancient ended but to stand only for the comparatively Recent. For example, in History, the ill-defined period called the Middle and Dark Ages makes a considerable hiatus before, in the process of retrospection, we get back to a civilization which (in Europe at least) we ordinarily regard as Ancient. Again, in History, we distinguish commonly two provinces within the undoubted area of the Ancient, the Prehistoric and the Historic, the first comprising all the time to which human memory, as communicated by surviving literature, ran not, or, at least, not consciously, consistently and credibly. At the same time it is not implied that we can have no knowledge at all of the Prehistoric province. It may even be better known to us than parts of the Historic, through sure deduction from archaeological evidence. But what we learn from archaeological records is annalistic not historic, since such records have not passed through the transforming crucible of a human intelligence which reasons on events as effects of causes. The boundary between Prehistoric and Historic, however, depends too much on the subjectivity of individual historians and is too apt to vary with the progress of research to be a fixed moment. Nor can it be the same for all civilizations. As regards Egypt, for example, we have a body of literary tradition which can reasonably be called Historic, relating to a time much earlier than is reached by respectable literary tradition of Elam and Babylonia, though their civilizations were probably older than the Egyptian. For the Ancient East as here understood, we possess two bodies of historic literary tradition and two only, the Greek and the Hebrew; and as it happens, both (though each is independent of the other) lose consistency and credibility when they deal with history before 1000 B.C. Moreover, Prof. Myres has covered the prehistoric period in the East in his brilliant _Dawn of History_. Therefore, on all accounts, in treating of the historic period, I am absolved from looking back more than a thousand years before our era.
