3. Nor do the writers who, many ages since Alexander’s time, have given an account of these countries, nor even those who at present make voyages thither, afford any precise information. Apollodorus, for instance, author of the Parthian History, when he mentions the Greeks who occasioned the revolt of Bactriana from the Syrian kings, who were the successors of [CAS. 686] Seleucus Nicator, says, that when they became powerful they invaded India. He adds no discoveries to what was previously known, and even asserts, in contradiction to others, that the Bactrians had subjected to their dominion a larger portion of India than the Macedonians; for Eucratidas (one of these kings) had a thousand cities subject to his authority. But other writers affirm that the Macedonians conquered nine nations situated between the Hydaspes[303] and the Hypanis,[304] and obtained possession of five hundred cities, not one of which was less than Cos Meropis,[305] and that Alexander, after having conquered all this country, delivered it up to Porus. 4. Very few of the merchants who now sail from Egypt by the Nile and the Arabian Gulf to India have proceeded as far as the Ganges; and, being ignorant persons, were not qualified to give an account of places they have visited. From one place in India, and from one king, namely, Pandion, or, according to others,[306] Porus, presents and embassies were sent to Augustus Cæsar. With the ambassadors came the Indian Gymno-Sophist, who committed himself to the flames at Athens,[307] like Calanus, who exhibited the same spectacle in the presence of Alexander. 5. If, then, we set aside these stories, and direct our attention to accounts of the country prior to the expedition of Alexander, we shall find them still more obscure. It is probable that Alexander, elated by his extraordinary good fortune, believed these accounts. According to Nearchus, Alexander was ambitious of conducting his army through Gedrosia,[308] when he heard that Semiramis and Cyrus had undertaken expeditions against India (through this country), although both had abandoned the enterprise, the former escaping with twenty, and Cyrus with seven men only. For he considered that it would be a glorious achievement for him to lead a conquering army safe through the same nations and countries where Semiramis and Cyrus had suffered such disasters. Alexander, therefore, believed these stories.
