The Persian monarchy appears, in fact, even as we look back upon it from this remote distance both of space and of time, as a very vast wave of human power and grandeur. It swelled up among the populations of Asia, between the Persian Gulf and the Caspian Sea, about five hundred years before Christ, and rolled on in undiminished magnitude and glory for many centuries. It bore upon its crest the royal line of Astyages and his successors. Cyrus was, however, the first of the princes whom it held up conspicuously to the admiration of the world and he rode so gracefully and gallantly on the lofty crest that mankind have given him the credit of raising and sustaining the magnificent billow on which he was borne. How far we are to consider him as founding the monarchy, or the monarchy as raising and illustrating him, will appear more fully in the course of this narrative.
Cotemporaneous with this Persian monarchy in the East, there flourished in the West the small but very efficient and vigorous republics of Greece. The Greeks had a written character for their language which could be easily and rapidly executed, while the ordinary language of the Persians was scarcely written at all. There was, it is true, in this latter nation, a certain learned character, which was used by the priests for their mystic records, and also for certain sacred books which constituted the only national archives. It was, however, only slowly and with difficulty that this character could be penned, and, when penned, it was unintelligible to the great mass of the population. For this reason, among others, the Greeks wrote narratives of the great events which occurred in their day, which narratives they so embellished and adorned by the picturesque lights and shades in which their genius enabled them to present the scenes and characters described as to make them universally admired, while the surrounding nations produced nothing but formal governmental records, not worth to the community at large the toil and labor necessary to decipher them and make them intelligible. Thus the Greek writers became the historians, not only of their own republics, but also of all the nations around them; and with such admirable genius and power did they fulfill this function, that, while the records of all other nations cotemporary with them have been almost entirely neglected and forgotten, the language of the Greeks has been preserved among mankind, with infinite labor and toil, by successive generations of scholars, in every civilized nation, for two thousand years, solely in order that men may continue to read these tales.
