189. Now when Cyrus on his way towards Babylon arrived at the river Gyndes,—of which river the springs are in the mountains of the Matienians, and it flows through the Dardanians and runs into another river, the Tigris, which flowing by the city of Opis runs out into the Erythraian Sea,—when Cyrus, I say, was endeavouring to cross this river Gyndes, which is a navigable stream, then one of his sacred white horses in high spirit and wantonness went into the river and endeavoured to cross, but the stream swept it under water and carried it off forthwith. And Cyrus was greatly moved with anger against the river for having done thus insolently, and he threatened to make it so feeble that for the future even women could cross it easily without wetting the knee. So after this threat he ceased from his march against Babylon and divided his army into two parts; and having divided it he stretched lines and marked out straight channels, 193 one hundred and eighty on each bank of the Gyndes, directed every way, and having disposed his army along them he commanded them to dig: so, as a great multitude was working, the work was completed indeed, but they spent the whole summer season at this spot working. 190. When Cyrus had taken vengeance on the river Gyndes by dividing it into three hundred and sixty channels, and when the next spring was just beginning, then at length he continued his advance upon Babylon: and the men of Babylon had marched forth out of their city and were awaiting him. So when in his advance he came near to the city, the Babylonians joined battle with him, and having been worsted in the fight they were shut up close within their city. But knowing well even before this that Cyrus was not apt to remain still, and seeing him lay hands on every nation equally, they had brought in provisions beforehand 194 for very many years. So while these made no account of the siege, Cyrus was in straits what to do, for much time went by and his affairs made no progress onwards.
