They say, also, that the Sydracæ (Oxydracæ) are descendants of Bacchus, because the vine grows in their country, and because their kings display great pomp in setting out on their warlike expeditions, after the Bacchic manner; whenever they appear in public, it is with beating of drums, and are dressed in flowered robes, which is the common custom among the other Indians. When Alexander took, on the first assault, Aornos,[315] a fortress on a rock, the foot of which is washed by the Indus near its source, his flatterers exaggerated this act, and said that Hercules thrice assailed this rock and was thrice repulsed. They pretended that the Sibæ[316] were descended from the people who accompanied Hercules in his expedition, and that they retained badges of their descent; that they wore skins like Hercules, and carried clubs, and branded with the mark of a club their oxen and mules. They confirm this fable with stories about Caucasus[317] and Prometheus, for they transferred hither from Pontus these tales, on the slight pretence that they had seen a sacred cave among the Paropamisadæ.[318] This they alleged was the prison of Prometheus, that Hercules came hither to release Prometheus, and that this mountain was the Caucasus, to which the Greeks represent Prometheus as having been bound. 9. That these are the inventions of the flatterers of Alexander is evident, first, because the writers do not agree with one another, some of whom speak of these things; others make no mention of them whatever. For it is not probable, that actions so illustrious, and calculated to foster pride and vanity, should be unknown, or if known, that they should not be thought worthy of record, especially by writers of the greatest credit. Besides, the intervening people, through whose country the armies of Bacchus and Hercules must have marched in their [CAS. 688] way to India, do not exhibit any proofs of their passage through the country. The kind of dress, too, of Hercules is much more recent than the memorials of Troy, an invention of those who composed the Heracleia (or exploits of Hercules,) whether it were Peisander or some one else who composed it. But the ancient wooden statues do not represent Hercules in that attire. 10. Under such circumstances, therefore, we must receive everything that approaches nearest to probability. I have already discussed this subject to the extent of my ability at the beginning of this work;[319] I shall now assume those opinions as clearly proved, and shall add whatever may seem to be required for the sake of perspicuity. It appeared from the former discussion, that in the summary given by Eratosthenes, in the third book of his Geography, is contained the most credible account of the country considered as India at the time of its invasion by Alexander.
