Arrian, Indica 5.3-9
 But even Megasthenes, so far as I can see, did not visit much of India, though he visited more than the followers of Alexander, son of Philip, did; he states that he was in the company of Sandrokottos, the greatest of all the Indian kings, even greater than Poros.
 This Megasthenes says that the Indians did not attack any other people, and none attacked them.  Now Sesostris the Egyptian, after subduing most of Asia and invading Europe with an army, returned home again;  while Idanthyrsos the Skythian, having started out from Skythia, subdued many peoples of Asia, then attacked the land of the Egyptian and took it.  And Semiramis the Assyrian made ready to set out against the Indians, but died before she could realize her plans. For Alexander alone made an expedition against the Indians.  And before Alexander, there is much talk about Dionysos, that he too had marched against the Indians and subdued them; but concerning Herakles the report is not so prevalent.
 And as for Dionysos, the city of Nysa is not a slight memorial of his campaign, as is Mt. Meros, and the ivy which grows on that mountain; and also the Indians themselves, who go to war to the sound of tympani and cymbals, and have a speckled dress, just as the Bacchai of Dionysos.
