132. Then Demokedes having healed king Darius had a very great house in Susa, and had been made a table-companion of the king; and except the one thing of returning to the land of the Hellenes, he had everything. And first as regards the Egyptian physicians who tried to heal the king before him, when they were about to be impaled because they had proved inferior to a physician who was a Hellene, he asked their lives of the king and rescued them from death: then secondly, he rescued an Eleian prophet, who had accompanied Polycrates and had remained unnoticed among the slaves. In short Demokedes was very great in the favor of the king.
133. Not long time after this another thing came to pass which was this:—Atossa the daughter of Cyrus and wife of Darius had a tumor upon her breast, which afterwards burst and then was spreading further: and so long as it was not large, she concealed it and said nothing to anybody, because she was ashamed; but afterwards when she was in evil case, she sent for Demokedes and showed it to him: and he said that he would make her well, and caused her to swear that she would surely do for him in return that which he should ask of her; and he would ask, he said, none of such things as are shameful.
134. So when after this by his treatment he had made her well, then Atossa instructed by Demokedes uttered to Darius in his bedchamber some such words as these: "O king, though thou hast such great power, thou dost sit still, and dost not win in addition any nation or power for the Persians: and yet it is reasonable that a man who is both young and master of much wealth should be seen to perform some great deed, in order that the Persians may know surely that he is a man by whom they are ruled. It is expedient indeed in two ways that thou shouldest do so, both in order that the Persians may know that their ruler is a man, and in order that they may be worn down by war and not have leisure to plot against thee. For now thou mightest display some great deed, while thou art still young; seeing that as the body grows the spirit grows old also with it, and is blunted for every kind of action." Thus she spoke according to instructions received, and he answered thus: "Woman, thou hast said all the things which I myself have in mind to do; for I have made the plan to yoke together a bridge from this continent to the other and to make expedition against the Scythians, and these designs will be by way of being fulfilled within a little time." Then Atossa said: "Look now,—forbear to go first against the Scythians, for these will be in thy power whenever thou desirest: but do thou, I pray thee, make an expedition against Hellas; for I am desirous to have Lacedemonian women and Argive and Athenian and Corinthian, for attendants, because I hear of them by report: and thou hast the man who of all men is most fitted to show thee all things which relate to Hellas and to be thy guide, that man, I mean, who healed thy foot." Darius made answer: "Woman, since it seems good to thee that we should first make trial of Hellas, I think it better to send first to them men of the Persians together with him of whom thou speakest, to make investigation, that when these have learnt and seen, they may report each several thing to us; and then I shall go to attack them with full knowledge of all."
135. Thus he said, and he proceeded to do the deed as he spoke the word: for as soon as day dawned, he summoned fifteen Persians, men of repute, and bade them pass through the coasts of Hellas in company with Demokedes, and take care not to let Demokedes escape from them, but bring him back at all costs. Having thus commanded them, next he summoned Demokedes himself and asked him to act as a guide for the whole of Hellas and show it to the Persians, and then return back: and he bade him take all his movable goods and carry them as gifts to his father and his brothers, saying that he would give him in their place many times as much; and besides this, he said, he would contribute to the gifts a merchant ship filled with all manner of goods, which should sail with him. Darius, as it seems to me, promised him these things with no crafty design; but Demokedes was afraid that Darius was making trial of him, and did not make haste to accept all that was offered, but said that he would leave his own things where they were, so that he might have them when he came back; he said however that he accepted the merchant ship which Darius promised him for the presents to his brothers. Darius then, having thus given command to him also, sent them away to the sea.
136. So these, when they had gone down to Phoenicia and in Phoenicia to the city of Sidon, forthwith manned two triremes, and besides them they also filled a large ship of burden with all manner of goods. Then when they had made all things ready they set sail for Hellas, and touching at various places they saw the coast regions of it and wrote down a description, until at last, when they had seen the greater number of the famous places, they came to Taras in Italy. There from complaisance to Demokedes Aristophilides the king of the Tarentines unfastened and removed the steering-oars of the Median ships, and also confined the Persians in prison, because, as he alleged, they came as spies. While they were being thus dealt with, Demokedes went away and reached Croton; and when he had now reached his own native place, Aristophilides set the Persians free and gave back to them those parts of their ships which he had taken away.
