SKETCH OF CYRUS THE YOUNGER. (Introductory to the Retreat of the Ten Thousand Greeks.) In the year 423 B.C. Darius Nothus ascended the throne of Persia. That country was then the greatest empire in the world, and had an area nearly equal to that of the United States. The capital of this seemingly powerful realm was the ancient city of Babylon on the lower Euphrates. Here the Great King, as he was styled, had his principal palace, from which he issued orders to his twenty or more satraps or governors whose provinces extended in name at least from the shores of the Mediterranean to the banks of the Indus, and from the Persian Gulf to the Black Sea. Darius had married his half-sister Parysatis, a high-spirited but unscrupulous woman, by whom he had two sons, destined to be known in history. The eldest was Artaxerxes, a youth of but little character; and the second, Cyrus, who inherited the decided qualities of his mother. In order to distinguish him from Cyrus the Great, the founder of the Persian Empire, who died more than a hundred years earlier, he is commonly called Cyrus the Younger. He was his mothers favorite, and as he was born after Darius assumed the crown, while Artaxerxes was born before that date, Parysatis seems to have encouraged Cyrus to consider himself the true heir to the throne, since he was in fact the kings eldest son. Through her influence he was appointed satrap of Lydia and the adjacent provinces of western Asia Minor when he was but sixteen. This position, since it made him the military ruler of that populous and wealthy section of country, was one of great importance, and doubtless had no small influence in shaping the young mans future career. In 44 Cyrus was summoned from Sardis, the capital of Lydia, to Babylon, and shortly after, his father died, leaving his crown to Artaxerxes, who, from his remarkable memory which appears to have been his chief characteristic, got the title of Artaxerxes Mnemon. But Cyrus certainly was not deficient in this mental quality, for he seems to have remembered his mothers suggestions about his being the rightful heir to the throne so well, that at the coronation of Artaxerxes he plotted his assassination; or at least, Tissaphernes, a neighboring satrap, accused him of it. Cyrus, who appears to have had no adequate defence to make, was forthwith arrested and would probably have been summarily put to death-for in Persia the laws delays were unknown-had not Parysatis interfered. Realizing her sons imminent peril, she rushed forward and, clasping him in her arms, wound her long flowing hair about him, and pressed his neck to hers in such a way that the executioner must have beheaded her with the same stroke with which he decapitated Cyrus. The prayers and entreaties of Parysatis saved the young mans life, and he was even permitted to return to Sardis and resume his power. He went; but with no intention of remaining in that subordinate position. Not only was he resolved to be revenged on Tissaphernes, but he was equally determined to overthrow the mild Artaxerxes and convince him of the mistake of yielding to a womans tears....
