He was at this time, if we may trust Dino, exactly forty years of age, and was thus at that happy period in life when the bodily powers have not yet begun to decay, while the mental are just reaching their perfection. Though we may not be able to trust implicitly the details of the war of independence which have come down to us, yet there can be no doubt that he had displayed in its course very remarkable courage and conduct. He had intended, probably, no more than to free his country from the Median yoke; by the force of circumstances he had been led on to the destruction of the Median power, and to the establishment of a Persian Empire in its stead. With empire had come an enormous accession of wealth. The accumulated stores of ages, the riches of the Ninevite kings--the “gold,” the “silver,” and the “pleasant furniture” of those mighty potentates, of which there was “none end”--together with all the additions made to these stores by the Median monarchs, had fallen into his hands, and from comparative poverty he had come per saltum into the position of one of the wealthiest--if not of the very wealthiest--of princes. An ordinary Oriental would have been content with such a result, and have declined to tempt fortune any more. But Cyrus was no ordinary Oriental. Confident in his own powers, active, not to say restless, and of an ambition that nothing could satiate, he viewed, the position which he had won simply as a means of advancing himself to higher eminence. According to Ctesias, he was scarcely seated upon the throne, when he led an expedition to the far north-east against the renowned Bactrians and Sacans; and at any rate, whether this be true or no--and most probably it is an anticipation of later occurrences--it is certain that, instead of folding his hands, Cyrus proceeded with scarcely a pause on a long career of conquest, devoting his whole life to the carrying out of his plans of aggression, and leaving a portion of his schemes, which were too extensive for one life to realize, as a legacy to his successor. The quarter to which he really first turned his attention seems to have been the north-west. There, in the somewhat narrow but most fertile tract between the river Halys and the Egean Sea, was a state which seemed likely to give him trouble--a state which had successfully resisted all the efforts of the Medes to reduce it, and which recently, under a warlike prince, had shown a remarkable power of expansion. An instinct of danger warned the scarce firmly-settled monarch to fix his eye at once upon Lydia; in the wealthy and successful Croesus, the Lydian king, he saw one whom dynastic interests might naturally lead to espouse the quarrel of the conquered Mede, and whose power and personal qualities rendered him a really formidable rival.
