"I hope," said he, addressing the king, "that it will not displease you to have other views presented in addition to those which have already been expressed. It is better that all opinions should be heard; the just and the true will then appear the more just and true by comparison with others. It seems to me that the enterprise which you contemplate is full of danger, and should be well considered before it is undertaken. When Darius, your father, conceived of the plan of his invasion of the country of the Scythians beyond the Danube, I counseled him against the attempt. The benefits to be secured by such an undertaking seemed to me wholly insufficient to compensate for the expense, the difficulties, and the dangers of it. My counsels were, however, overruled. Your father proceeded on the enterprise. He crossed the Bosporus, traversed Thrace, and then crossed the Danube; but, after a long and weary contest with the hordes of savages which he found in those trackless wilds, he was forced to abandon the undertaking, and return, with the loss of half his army. The plan which you propose seems to me to be liable to the same dangers, and I fear very much that it will lead to the same results. "The Greeks have the name of being a valiant and formidable foe. It may prove in the end that they are so. They certainly repulsed Datis and all his forces, vast as they were, and compelled them to retire with an enormous loss. Your invasion, I grant, will be more formidable than his. You will throw a bridge across the Hellespont, so as to take your troops round through the northern parts of Europe into Greece, and you will also, at the same time, have a powerful fleet in the AEgean Sea. But it must be remembered that the naval armaments of the Greeks in all those waters are very formidable. They may attack and destroy your fleet. Suppose that they should do so, and that then, proceeding to the northward in triumph, they should enter the Hellespont and destroy your bridge? Your retreat would be cut off, and, in case of a reverse of fortune, your army would be exposed to total ruin. "Your father, in fact, very narrowly escaped precisely this fate. The Scythians came to destroy his bridge across the Danube while his forces were still beyond the river, and, had it not been for the very extraordinary fidelity and zeal of Histiaeus, who had been left to guard the post, they would have succeeded in doing it. It is frightful to think that the whole Persian army, with the sovereign of the empire at their head, were placed in a position where their being saved from overwhelming and total destruction depended solely on the fidelity and firmness of a single man! Should you place your forces and your own person in the same danger, can you safely calculate upon the same fortunate escape?
