sides of the Euphrates to continue the blockade of the city and of Borsippa, it could detach an adequate force of troops and workmen to Sepharvaim. Before these works could be begun, the inundation which in June and July the Euphrates pours over the plain of Babylon must have been over; and before the return of the inundation in the autumn, which would imperil the whole undertaking, Sepharvaim must be captured, the Euphrates drawn off, and Babylon conquered. When Sepharvaim was in the hand of Cyrus, the stream, which had previously been dammed up with the exception of a small passage, must have been rapidly closed, that the Babylonians might not have their suspicions roused by the fall of the water, and guard the walls on the river with redoubled vigilance. The time was short. Pliny has preserved for us the statement that the large city of Agranis, which lay on the Euphrates, where the canal Nahr Malka (III. 359) flowed out of the river, was destroyed by the Persians; the walls of the city of Sepharvaim which had been rendered famous by the wisdom of the Chaldæans (Sippara, I. 245), were also destroyed by the Persians, and Gobares (Gobryas), as some say, had drawn off the Euphrates.[76] To Gobryas Xenophon also allots an important share in the capture of Babylon (p. 78). Even without these statements of Pliny, which support the account of Herodotus, and inform us of the battles which the Persians had to fight on the Euphrates above Babylon in order to establish themselves at the entrance of the Nahr Malka, and get the mouth of the basin into their power--even without the hints of the prophets of the Hebrews about the "drying up of the springs," and "parching of the channels," and the remark of Polyaenus about the drawing off of the Euphrates at a marsh (the basin of Sepharvaim was, when not filled, a marsh), we must reject Xenophon's account of the drawing off of the Euphrates. Conceding the extent of the walls of Babylon, even if limited to one bank of the river, the work could not have been done in a year; and every day the execution of the work under the eyes of the besieged would have made its object more plain.
