But, of course, commerce builds up local industries. A nation must be a producer of useful commodities before it can hope to secure, by peaceful means, the commodities produced by other nations. In connection with the commercial relations of a nation we must study also its home industries, that is to say, broadly speaking, its agricultural and manufacturing conditions. We must see something also of the social customs that grow out of, and rest upon these industrial conditions; and of the laws that are the official expression of the communal intelligence—the index of the communal conscience of the epoch.
BABYLON AND ITS CUSTOMS DESCRIBED BY AN EYE-WITNESS
The Assyrians are masters of many capital towns; but their place of greatest strength and fame is Babylon, which, after the destruction of Nineveh, was the royal residence. It is situated on a large plain, and is a perfect square; each side, by every approach, is 120 furlongs in length; the space, therefore, occupied by the whole is 480 furlongs. [The different reports of the extent of the walls of Babylon are given as follows: By Herodotus at 120 stadia each side, or 480 in circumference. By Pliny and Solinus at 60 Roman miles, which, at eight stadia to a mile, agrees with Herodotus. By Strabo at 385 stadia. By Diodorus, from Ctesias, 360; but from Clitarchus, who accompanied Alexander, 365; and, lastly, by Curtius, 368. It appears highly probable that 360 or 365 was the true statement of the circumference.]
So extensive is the ground which Babylon occupies, its internal beauty and magnificence exceeds whatever has come within my knowledge. It is surrounded by a trench, very wide, deep, and full of water; the wall beyond this is two hundred royal cubits high, and fifty wide; the royal exceeds the common cubit by three digits. [These measures, being taken from the proportions of the human body, are more permanent than any other. The foot of a moderate-sized man and the cubit, that is the space from the end of the fingers to the elbow, have always been near twelve and eighteen inches respectively.—Beloe.]
I here think it right to describe the use to which the earth dug out of the trench was converted, as well as the particular manner in which they constructed the wall. The earth of the trench was first of all laid in heaps, and, when a sufficient quantity was obtained, made into square bricks and baked in a furnace. They used as cement a composition of heated bitumen, which, mixed with tops of reeds, was placed betwixt every thirtieth course of bricks. Having thus lined the sides of the trench, they proceeded to build the wall in the same manner, on the summit of which, and fronting each other, they erected small watch-towers of one story, leaving a space betwixt them, through which a chariot and four horses might pass and turn. In the circumference of the wall, at different distances, were an hundred massy gates of brass, whose hinges and frames were of the same metal. Within an eight days’ journey from Babylon is a city called Is [Hit], near which flows a river of the same name, which empties itself into the Euphrates. With the current of this river, particles of bitumen descend towards Babylon, by the means of which its walls were constructed. The great river Euphrates, which, with its deep and rapid streams, rises in the Armenian Mountains, and pours itself into the Red Sea, divides Babylon into two parts. The walls meet and form an angle with the river at each extremity of the town, where a breastwork of burnt bricks begins, and is continued along each bank. The city, which abounds in houses from three to four stories in height, is regularly divided into streets. Through these, which are parallel, there are transverse avenues to the river, opened through the wall and breastwork, and secured by an equal number of little gates of brass.
