Then, turning upon his interlocutor, Christ inquires why he is so anxious to promote the one whose rise will entail his fall? To which Satan replies that, having no hope, it little behooves him to obstruct the plans of Christ, from whose benevolence alone he expects some mitigation of his punishment, for he fancies that by speaking thus he can best induce Christ to hear him. Then, feigning to believe that Christ has refused his offers simply because he has never seen aught save Jerusalem, Satan conveys him in the twinkling of an eye to the summit of a mountain, whence, pointing eastward, he shows him all the great kingdoms of Asia. Thus, he reveals the glories of Assyria, Babylonia, and Persia,--of whose histories he gives a brief résumé,--before pointing out a large Parthian army setting out to war against the Scythians, for he hopes by this martial display to convince Christ that, in order to obtain a kingdom, he will have to resort to military force. Then he adds he can easily enlist the services of this army, with which Christ can drive the Romans out of Judea, and triumphantly reign over the land of his ancestors, whence his glory will extend far and wide, until it far surpasses all that Rome and Caesar achieved. Jesus, however, demonstrates the vanity of all military efforts, declaring his time has not yet come, but assuring him he will not be found wanting when the moment comes for him to ascend the throne, for he hopes to prove an able ruler. Then he reminds Satan how he tempted David to take a census against God's wish, and led Israel astray, until the Ten Tribes were taken off into captivity in punishment for their idolatry. He also comments upon Satan's extraordinary anxiety to restore the very people whose foe he has always been, as he has proved time and again by leading them into idolatry, adding that God may yet restore them to their liberty and to their native land. These arguments silence even Satan, for such is ever the result when "with truth falsehood contends." _Book IV._ With all the persistency of his kind, Satan refuses to acknowledge himself beaten, and, leading Christ to the western side of the mountain, reveals to him all the splendor of Rome, exhibiting its Capitol, Tarpeian Rock, triumphal arches, and the great roads along which hosts are journeying to the Eternal City. After thus dazzling him, Satan suggests that Christ oust Tiberius (who has no son) from the imperial throne, and make himself master not only of David's realm, but of the whole Roman Empire, establishing law and order where vice now reigns.
