He had a brother whom he had shut up in a dungeon, and whose mind, naturally depraved, and irritated by his injuries, was in a state of malignant and furious despair. Mæandrius had pretended to be willing to give up the island to the Persians. He had entered into negotiations with them for this purpose, and the Persians considered the treaty as in fact concluded. The leaders and officers of the army had assembled, accordingly, before the citadel in a peaceful attitude, waiting merely for the completion of the forms of surrender, when Charilaus, Mæandrius's captive brother, saw them, by looking out between the bars of his window, in the tower in which he was confined. He sent an urgent message to Mæandrius, requesting to speak to him. Mæandrius ordered the prisoner to be brought before him. The haggard and wretched-looking captive, rendered half insane by the combined influence of the confinement he had endured, and of the wild excitement produced by the universal panic and confusion which reigned around him, broke forth against his brother in the boldest and most violent invectives. He reproached him in the most bitter terms for being willing to yield so ingloriously, and without a struggle, to an invading foe, whom he might easily repel. "You have courage and energy enough, it seems," said he, "to make war upon an innocent and defenseless brother, and to keep him for years in chains and in a dungeon, but when an actual enemy appears, though he comes to despoil you of all your possessions, and to send you into hopeless exile, and though, if you had the ordinary courage and spirit of a man, you could easily drive him away, yet you dare not face him. If you are too cowardly and mean to do your duty yourself, give me your soldiers, and I will do it for you. I will drive these Persians back into the sea with as much pleasure as it would give me to drive you there!"
Such a nature as that of Mæandrius can not be stung into a proper sense of duty by reproaches like these. There seem to have been in his heart no moral sensibilities of any kind, and there could be, of course, no compunctions for the past, and no awakening of new and better desires for the future. All the effect which was produced upon his mind by these bitter denunciations was to convince him that to comply with his brother's request would be to do the best thing now in his power for widening, and extending, and making sure the misery and mischief which were impending. He placed his troops, therefore, under his brother's orders; and while the infuriated madman sallied forth at the head of them to attack the astonished Persians on one side of the citadel, Mæandrius made his escape through the under-ground passage on the other. The Persians were so exasperated at what appeared to them the basest treachery, that, as soon as they could recover their arms and get once more into battle array, they commenced a universal slaughter of the Samians. They spared neither age, sex, nor condition; and when, at last, their vengeance was satisfied, and they put the island into Syloson's hands, and withdrew, he found himself in possession of an almost absolute solitude.
[Illustration: THE BABYLONIANS DERIDING DARIUS.]
It was while Otanes was absent on this enterprise, having with him a large part of the disposable forces of the king, that the Babylonians revolted. Darius was greatly incensed at hearing the tidings. Sovereigns are always greatly incensed at a revolt on the part of their subjects. The circumstances of the case, whatever they may be, always seem to them to constitute a peculiar aggravation of the offense. Darius was indignant that the Babylonians had attempted to take advantage of his weakness by rebelling when his armies were away. If they had risen when his armies were around him, he would have been equally indignant with them for having dared to brave his power.
He assembled all the forces at his disposal, and advanced to Babylon. The people of the city shut their gates against him, and derided him. They danced and capered on the walls, making all sorts of gestures expressive of contempt and defiance, accompanied with shouts and outcries of ridicule and scorn. They had great confidence in the strength of their defenses, and then, besides this, they probably regarded Darius as a sort of usurper, who had no legitimate title to the throne, and who would never be able to subdue any serious resistance which might be offered to the establishment of his power. It was from these considerations that they were emboldened to be guilty of the folly of taunting and insulting their foes from the city walls.
Such incidents as this, of personal communications between masses of enemies on the eve of a battle, were very common in ancient warfare, though impossible in modern times. In those days, when the missiles employed were thrown chiefly by the strength of the human arm alone, the combatants could safely draw near enough together for each side to hear the voices and to see the gesticulations of the other. Besiegers could advance sufficiently close to a castle or citadel to parley insultingly with the garrison upon the walls, and yet be safe from the showers of darts and arrows which were projected toward them in return. But all this is now changed. The reach of cannon, and even of musketry, is so long, that combatants, approaching a conflict, are kept at a very respectful distance apart, until the time arrives in which the actual engagement is to begin. They reconnoiter each other with spy-glasses from watch-towers on the walls, or from eminences in the field, but they can hold no communication except by a formal embassy, protected by a flag of truce, which, with its white and distant fluttering, as it slowly advances over the green fields, warns the gunners at the battery or on the bastion to point their artillery another way.
The Babylonians, on the walls of their city, reproached and taunted their foes incessantly. "Take our advice," said they, "and go back where you came from. You will only lose your time in besieging Babylon. When mules have foals, you will take the city, and not till then."
The expression "when mules have foals" was equivalent in those days to our proverbial phrase, "when the sky falls," being used to denote any thing impossible or absurd, inasmuch as mules, like other hybrid animals, do not produce young. It was thought in those times absolutely impossible that they should do so; but it is now well known that the case is not impossible, though very rare.
It seems to have added very much to the interest of an historical narrative in the minds of the ancient Greeks, to have some prodigy connected with every great event; and, in order to gratify this feeling, the writers appear in some instances to have fabricated a prodigy for the occasion, and in others to have elevated some unusual, though by no means supernatural circumstance, to the rank and importance of one. The prodigy connected with this siege of Babylon was the foaling of a mule. The mule belonged to a general in the army of Darius, named Zopyrus. It was after Darius had been prosecuting the siege of the city for a year and a half, without any progress whatever toward the accomplishment of his end. The army began to despair of success. Zopyrus, with the rest, was expecting that the siege would be indefinitely prolonged, or, perhaps, absolutely abandoned, when his attention was strongly attracted to the phenomenon which had happened in respect to the mule. He remembered the taunt of the Babylonian on the wall, and it seemed to him that the whole occurrence portended that the time had now arrived when some way might be devised for the capture of the city.
