Paragraph 178 178. Cyrus, so soon as he had made subject to himself all other parts of the mainland, proceeded to attack the Assyrians. Now Assyria has doubtless many other great cities, but the most famous and the strongest, and the place where the seat of their monarchy had been established after Nineveh was destroyed, was Babylon; which was a city such as I shall say.—It lies in a great plain, and in size it is such that each face measures one hundred and twenty furlongs, 177 the shape of the whole being square; thus the furlongs of the circuit of the city amount in all to four hundred and eighty. Such is the size of the city of Babylon, and it had a magnificence greater than all other cities of which we have knowledge. First there runs round it a trench deep and broad and full of water; then a wall fifty royal cubits in thickness and two hundred cubits in height: now the royal cubit is larger by three fingers than the common cubit. 178
Paragraph 179 179. I must also tell in addition to this for what purpose the earth was used, which was taken out of the trench, and in what manner the wall was made. As they dug the trench they made the earth which was carried out of the excavation into bricks, and having moulded enough bricks they baked them in kilns; and then afterwards, using hot asphalt for mortar and inserting reed mats at every thirty courses of brickwork, they built up first the edges of the trench and then the wall itself in the same manner: and at the top of the wall along the edges they built chambers of one story facing one another; and between the rows of chambers they left space to drive a four-horse chariot. In the circuit of the wall there are set a hundred gates made of bronze throughout, and the gate-posts and lintels likewise. Now there is another city distant from Babylon a space of eight days' journey, of which the name is Is; and there is a river there of no great size, and the name of the river is also Is, and it sends its stream into the river Euphrates. This river Is throws up together with its water lumps of asphalt in great abundance, and thence was brought the asphalt for the wall of Babylon.
