He now employed the fleet among the islands of the Cyclades, for the purpose of levying fines upon them as a punishment for adherence to the Persian. He first laid siege to Andros, telling the inhabitants that he came to demand their money, bringing with him two great gods,—Persuasion and Necessity. To which the Andrians replied, that “Athens was a great city, and blest with excellent gods: but that _they_ were miserably poor, and that there were two unkind gods who always stayed with them and would never quit the island,—Poverty and Helplessness.[279] In these gods the Andrians put their trust, refusing to deliver the money required; for the power of Athens could never overcome their inability.” While the fleet was engaged in contending against the Andrians with their sad protecting deities, Themistoklês sent round to various other cities, demanding from them private sums of money on condition of securing them from attack. From Karystus, Paros, and other places, he thus extorted bribes for himself apart from the other generals,[280] but it appears that Andros was found unproductive, and after no very long absence, the fleet was brought back to Salamis.[281] [279] Herodot. viii, 111. ἐπεὶ Ἀνδρίους γε εἶναι γεωπείνας ἐς τὰ μέγιστα ἀνήκοντας, καὶ θεοὺς δύο ἀχρήστους οὐκ ἐκλείπειν σφέων τὴν νῆσον, ἀλλ’ ἀεὶ φιλοχωρέειν—Πενίην τε καὶ Ἀμηχανίην. Compare Alkæus, Fragm. 90, ed. Bergk, and Herodot. vii, 172. [280] Herodot. viii, 112; Plutarch, Themistoklês, c. 21,—who cites a few bitter lines from the contemporary poet Timokreon. [281] Herodot. viii, 112-121. The intimation sent by Themistoklês perhaps had the effect of hastening the departure of Xerxes, who remained in Attica only a few days after the battle of Salamis, and then withdrew his army through Bœotia into Thessaly, where Mardonius made choice of the troops to be retained for his future operations. He retained all the Persians, Medes, Sakæ, Baktrians, and Indians, horse as well as foot, together with select detachments of the remaining contingents: making in all, according to Herodotus, three hundred thousand men. But as it was now the beginning of September, and as sixty thousand out of his forces, under Artabazus, were destined to escort Xerxes himself to the Hellespont, Mardonius proposed to Winter in Thessaly, and to postpone farther military operations until the ensuing spring.[282] [282] Herodot. viii, 114-126.
