In the mean time, Harpagus, though he had, at the time when he endured the horrid punishment which Astyages inflicted upon him, expressed no resentment, still he had secretly felt an extreme indignation and anger, and he had now, for fifteen years, been nourishing covert schemes and plans for revenge. He remained all this time in the court of Astyages, and was apparently his friend. He was, however, in heart a most bitter and implacable enemy. He was looking continually for a plan or prospect which should promise some hope of affording him his long-desired revenge. His eyes were naturally turned toward Cyrus. He kept up a communication with him so far as it was possible, for Astyages watched very closely what passed between the two countries, being always suspicious of plots against his government and crown. Harpagus, however, contrived to evade this vigilance in some degree. He made continual reports to Cyrus of the tyranny and misgovernment of Astyages, and of the defenselessness of the realm of Media, and he endeavored to stimulate his rising ambition to the desire of one day possessing for himself both the Median and Persian throne. In fact, Persia was not then independent of Media. It was more or less connected with the government of Astyages, so that Cambyses, the chief ruler of Persia, Cyrus's father, is called sometimes a king and sometimes a _satrap_, which last title is equivalent to that of viceroy or governor general. Whatever his true and proper title may have been, Persia was a Median dependency, and Cyrus, therefore, in forming plans for gaining possession of the Median throne, would consider himself as rather endeavoring to rise to the supreme command in his own native country, than as projecting any scheme for foreign conquest. Harpagus, too, looked upon the subject in the same light. Accordingly, in pushing forward his plots toward their execution, he operated in Media as well as Persia, He ascertained, by diligent and sagacious, but by very covert inquiries, who were discontented and ill at ease under the dominion of Astyages, and by sympathizing with and encouraging them, he increased their discontent and insubmission. Whenever Astyages, in the exercise of his tyranny inflicted an injury upon a powerful subject, Harpagus espoused the cause of the injured man, condemned, with him, the intolerable oppression of the king, and thus fixed and perpetuated his enmity. At the same time, he took pains to collect and to disseminate among the Medes all the information which he could obtain favorable to Cyrus, in respect to his talents, his character, and his just and generous spirit, so that, at length, the ascendency of Astyages, through the instrumentality of these measures, was very extensively undermined, and the way was rapidly becoming prepared for Cyrus's accession to power.
