Still, however, a part of the population appears to have returned to their former seats, for in the early part of the second century of the Christian era we find the Parthian king, Evemerus, sending numerous families from Babylon into Media to be sold as slaves, and burning many great and beautiful edifices still standing in the city.
In the time of Augustus, the city is said to have been entirely deserted, except by a few Jews who still lingered amongst the ruins. St. Cyril, of Alexandria, declares, that in his day, about the beginning of the fifth century, in consequence of the choking up of the great canals derived from the Euphrates, Babylon had become a vast marsh: and fifty years later the river is described as having changed its course, leaving only a small channel to mark its ancient bed. Then were verified the prophecies of Isaiah and Jeremiah, that the mighty Babylon should be but “pools of water,” “that the sea should come upon her, and that she should be covered with the multitude of the waves thereof.”[222]
In the beginning of the seventh century, at the time of the Arab invasion, the ancient cities of Babylonia were “a desolation, a dry land, and a wilderness.” Amidst the heaps that marked the site of Babylon herself there rose the small town of Hillah.[223]
Long before Babylon had overcome her rival Nineveh she was famous for the extent and importance of her commerce. No position could have then been more favourable than hers for carrying on a trade with all the regions of the known world. Even only moderate skill and enterprise could scarcely fail to make Babylon, not only the emporium of the Eastern world, but the main link of commercial intercourse between the East and the West.
The inhabitants did not neglect the advantages bestowed upon them by nature. A system of navigable canals that may excite the admiration of even the modern engineer, connected together the Euphrates and Tigris, those great arteries of her commerce. With a skill, showing no common knowledge of the art of surveying, and of the principles of hydraulics, the Babylonians took advantage of the different levels in the plains, and of the periodical rises in the two rivers, to complete the water communication between all parts of the province, and to fertilise by artificial irrigation an otherwise barren and unproductive soil. Alexander, after he had transferred the seat of his empire to the East, so fully understood the importance of these great works, that he ordered them to be cleansed and repaired, and superintended the work in person, steering his boat with his own hand through the channels.
High-roads and causeways across the Desert united Syria and Palestine with Babylonia. Fortified stations protected the merchant from the wandering tribes of Arabia, walled cities served as resting-places and store-houses, and wells at regular intervals gave an abundant supply of water during the hottest season of the year. One of those highways was carried through the centre of Mesopotamia, and crossing the Euphrates near the town of Anthemusia led into central Syria. A second appears to have left Babylon by the western quarter of the city, and entered Idumæa, after passing through the country of the Nabathæans. Others branched off to Tadmor, and to cities which were built in the midst of the Desert almost solely for purposes of trade.
To the east of Babylonia was the celebrated military and commercial road described by Herodotus. It led from Sardis to Susa in ninety days journey, and was furnished, at intervals of about fifteen miles, with stations and public hostelries, probably resembling the modern caravanserais of Persia.
Merchandise and travellers descended the rivers upon rafts of skins, as well as in boats built of reeds coated with bitumen, or of more solid materials. The land trade was no doubt principally carried on, as at the present day, by caravans of merchants, who loaded their goods on the backs of camels, horses, and asses.
It is difficult to determine to how far the Babylonians may have navigated in vessels the Indian Ocean. Of the various articles of merchandise stored in Babylon, the produce of the islands and shores of the Persian Gulf, and even of India, formed no inconsiderable part. Pearls, from the fisheries of Bahrein, which still supply Arabia, Persia, and Turkey, and perhaps even from Ceylon; cotton, spices, frankincense, precious stones, ivory, ebony, silks, and dyes, were amongst the objects of trade brought to her markets. They could only have been obtained from the southern coasts of Arabia, and directly or indirectly from the Indian peninsula. We learn from the Kouyunjik inscriptions that the people inhabiting the country at the mouths of the united waters of the Tigris and Euphrates possessed vessels in which, when defeated by the Assyrians, they took refuge on the sea. The prophet Isaiah also alludes to the ships of the Chaldæans.[224] Timber for shipbuilding could have been floated with ease from the mountains of Armenia to the very quays of Babylon, or to her ports at the head of the Persian Gulf.
A race of dogs, much prized by the Babylonians, was brought from India. A satrap of Babylon is declared to have devoted the revenues of four cities, to the support of a number of these animals. On a small terracotta tablet in the British Museum, from Col. Rawlinson’s collection, obtained, I believe, at Baghdad, but probably found in some ancient ruin in the neighbourhood, is the figure of a man leading a large and powerful dog, which has been identified with a species still existing in Thibet.
