Strabo Geography 15.1.6

[6] But how can we place any just confidence in the accounts of India derived from such expeditions as those of Cyrus and Semiramis? Megasthenes concurs in this opinion; he advises persons not to credit the ancient histories of India, for, except the expeditions of Hercules, of Bacchus, and the later invasion of Alexander, no army was ever sent out of their country by the Indians, nor did any foreign enemy ever invade or conquer it. Sesostris the Egyptian (he says), and Tearco the Ethiopian, advanced as far as Europe; and Nabocodrosor, who was more celebrated among the Chaldaeans than Hercules among the Greeks, penetrated even as far as the Pillars, ¹ which Tearco also reached; Sesostris conducted an army from Iberia to Thrace and Pontus; Idanthyrsus the Scythian overran Asia as far as Egypt; but not one of these persons proceeded as far as India, and Semiramis died before her intended enterprise was undertaken. The Persians had sent for the Hydraces ² from India, a body of mercenary troops; but they did not lead an army into that country, and only approached it when Cyrus was marching against the Massagetae.
