4. There was in the army a certain Xenophon, an Athenian, who accompanied it neither in the character of general, nor captain, nor common soldier, but it had happened that Proxenus, an old guest-friend of his, had sent for him from home, giving him a promise that, if he came, he would recommend him to the friendship of Cyrus, whom he considered, he said, as a greater object of regard than his own country. 5. Xenophon, on reading the letter, consulted Socrates the Athenian, as to the propriety of making the journey; and Socrates, fearing that if he attached himself to Cyrus it might prove a ground for accusation against him with his country, because Cyrus was thought to have zealously assisted the Lacedæmonians in their war with Athens, advised Xenophon to go to Delphi, and consult the god respecting the expedition. 6. Xenophon, having gone thither accordingly, inquired of Apollo to which of the gods he should sacrifice and pray, in order most honourably and successfully to perform the journey which he contemplated, and, after prosperously accomplishing it, to return in safety. Apollo answered him that "he should sacrifice to the gods to whom it was proper for him to sacrifice."[119] 7. When he returned, he repeated the oracle to Socrates, who, on hearing it, blamed him for not asking Apollo in the first place, whether it were better for him to go or stay at home; whereas, having settled with himself that he would go, he only asked how he might best go; "but since you have," said he, "put the question thus, you must do what the god has directed." 8. Xenophon, therefore, having sacrificed to the gods that Apollo commanded, set sail, and found Proxenus and Cyrus at Sardis, just setting out on their march up the country, and was presented to Cyrus. 9. Proxenus desiring that he should remain with them, Cyrus joined in the same desire, and said that as soon as the expedition was ended, he would send him home again. The expedition was said to be intended against the Pisidians. 10. Xenophon accordingly joined in the enterprise, being thus deceived, but not by Proxenus; for he did not know that the movement was against the king, nor did any other of the Greeks, except Clearchus. When they arrived in Cilicia, however, it appeared manifest to every one that it was against the king that their force was directed; but, though they were afraid of the length of the journey, and unwilling to proceed, yet the greater part of them, out of respect[120] both for one another and for Cyrus, continued to follow him; of which number was Xenophon.
