Xenophon Anabasis 2.1.3

[3] When they were on the point of setting out, and just as the sun was rising, came Procles, the ruler of Teuthrania, a descendant of Damaratus, ¹ the Laconian, and with him Glus, the son of Tamos. They reported that Cyrus was dead, and that Ariaeus had fled and was now, along with the rest of the barbarians, at the stopping-place from which they had set out on the preceding day; further, he sent word that he and his troops were that day waiting for the Greeks, on the chance that they intended to join them, but on the next day, so Ariaeus said, he should set out on the return journey for Ionia , whence he had come.
