to them.  This exodus extended over nearly two months, during March-esvan and Adar, and on its termination a proclamation of six days of mourning, up to the 3rd of Nisan, was made for the death of Bel-sharuzur, and as an atonement for the faults of Nabonidus, after which, on the 4th of Nisan, the notables of the city were called together in the temple of Nebo to join in the last expiatory ceremonies.  Cyrus did not hesitate for a moment to act as Tiglath-pileser III. and most of the Sargonids had done; he “took the hands of Bel,” and proclaimed himself king of the country, but in order to secure the succession, he associated his son Cambyses with himself as King of Babylon.  Mesopotamia having been restored to order, the provinces in their turn transferred their allegiance to Persia; “the kings enthroned in their palaces, from the Upper Sea to the Lower, those of Syria and those who dwell in tents, brought their weighty tribute to Babylon and kissed the feet of the suzerain.”  Events had followed one another so quickly, and had entailed so little bloodshed, that popular imagination was quite disconcerted:  it could not conceive that an empire of such an extent and of so formidable an appearance should have succumbed almost without a battle, and three generations had not elapsed before an entire cycle of legends had gathered round the catastrophe.  They related how Cyrus, having set out to make war, with provisions of all kinds for his household, and especially with his usual stores of water from the river Choaspes, the only kind of which he deigned to drink, had reached the banks of the Gyndes.  While seeking for a ford, one of the white horses consecrated to the sun sprang into the river, and being overturned by the current, was drowned before it could be rescued.  Cyrus regarded this accident as a personal affront, and interrupted his expedition to avenge it.  He employed his army during one entire summer in digging three hundred and sixty canals, and thus caused the principal arm of the stream to run dry, and he did not resume his march upon Babylon till the following spring, when the level of the water was low enough to permit of a woman crossing from one bank to the other without wetting her knees.  The Babylonians at first attempted to prevent the blockade of the place, but being repulsed in their sorties, they retired within the walls, much to Cyrus’s annoyance, for they were provisioned for several years.  He therefore undertook to turn the course of the Euphrates into the Bahr-i-Nejif, and having accomplished it, he crept into the centre of the city by the dry bed of the river.  If the Babylonians had kept proper guard, the Persians would probably have been surrounded and caught like fish in a net; but on that particular day they were keeping one of their festivals, and continued their dancing and singing till they suddenly found the streets alive with the enemy.
