This triumphant justification extorted even from Croesus himself a full confession that the sin lay with him, and not with the god. It certainly illustrates in a remarkable manner the theological ideas of the time. It shows us how much, in the mind of Herodotus, the facts of the centuries preceding his own, unrecorded as they were by any contemporary authority, tended to cast themselves into a sort of religious drama; the threads of the historical web being in part put together, in part originally spun, for the purpose of setting forth the religious sentiment and doctrine woven in as a pattern. The Pythian priestess predicts to Gyges that the crime which he had committed in assassinating his master would be expiated by his fifth descendant, though, as Herodotus tells us, no one took any notice of this prophecy until it was at last fulfilled: we see thus the history of the first Mermnad king is made up after the catastrophe of the last. There was something in the main facts of the history of Croesus profoundly striking to the Greek mind, a king at the summit of wealth and power—pious in the extreme and munificent toward the gods—the first destroyer of Hellenic liberty in Asia—then precipitated, at once and on a sudden, into the abyss of ruin. The sin of the first parent helped much toward the solution of this perplexing problem, as well as to exalt the credit of the oracle, when made to assume the shape of an unnoticed prophecy. In the affecting story of Solon and Crœsus, the Lydian king is punished with an acute domestic affliction because he thought himself the happiest of mankind—the gods not suffering any one to be arrogant except themselves; and the warning of Solon is made to recur to Crœsus after he has become the prisoner of Cyrus, in the narrative of Herodotus. To the same vein of thought belongs the story, just recounted, of the relations of Crœsus with the Delphian oracle. An account is provided, satisfactory to the religious feelings of the Greeks, how and why he was ruined—but nothing less than the overruling and omnipotent Mœræ could be invoked to explain so stupendous a result. It is rarely that these supreme goddesses—or hyper-goddesses, since the gods themselves must submit to them—are brought into such distinct light and action. Usually they are kept in the dark, or are left to be understood as the unseen stumbling block in cases of extreme incomprehensibility; and it is difficult clearly to determine (as in the case of some complicated political constitutions) where the Greeks conceived sovereign power to reside, in respect to the government of the world. But here the sovereignity of the Mœræ, and the subordinate agency of the gods, are unequivocally set forth. The gods are still extremely powerful, because the Mœræ comply with their requests up to a certain point, not thinking it proper to be wholly inexorable; but their compliance is carried no farther than they themselves choose; nor would they, even in deference to Apollo, alter the original sentence of punishment for the sin of Gyges in the person of his fifth descendant—sentence, moreover, which Apollo himself had formerly prophesied shortly after the sin was committed, so that, if the Mœræ had listened to his intercession on behalf of Crœsus, his own prophetic credit would have been endangered. Their unalterable resolution has predetermined the ruin of Crœsus, and the grandeur of the event is manifested by the circumstance that even Apollo himself cannot prevail upon them to alter it, or to grant more than a three years' respite. The religious element must here be viewed as giving the form, the historical element as giving the matter only, and not the whole matter, of the story. These two elements will be found conjoined more or less throughout most of the history of Herodotus, though as we descend to later times, we shall find the latter element in constantly increasing proportion. His conception of history is extremely different from that of Thucydides, who lays down to himself the true scheme and purpose of the historian, common to him with the philosopher—to recount and interpret the past, as a rational aid toward pre-vision of the future.
In the short abstract which we now possess of the lost work of Ctesias, no mention appears of the important conquest of Babylon. His narrative, indeed, as far as the abstract enables us to follow it, diverges materially from that of Herodotus, and must have been founded on data altogether different.
