These stones begin to form a particular class, since the curiosities called Babylonian cylinders have become less rare. Many of them have undoubtedly served for seal rings; for in the East the seal supplies the place of a signature, or at any rate makes it valid, as we still see on specimens of Babylonian documents. The same may be said of the cylinders. We have a striking illustration of the perfection to which the Babylonians had brought the art of cutting precious stones in the collection of M. Dorow, which contains a cylinder, formed from a jasper, bearing a cuneiform inscription, and an image of a winged Ized, or Genius, in a flowing Babylonian dress, represented in the act of crushing with each hand an ostrich, the bird of Ahriman. These various manufactures and works of art presuppose an extensive commerce, because the necessary materials must have been imported from foreign countries.
From what has been already adduced, no doubt can be entertained that Babylon enjoyed a lively commerce with the principal countries of the Persian Empire. Not only did the Persian and Median lords decorate their houses with the productions of Babylonian skill, but the kings of Persia spent a great part of the year in that city with all their numerous attendants, added to which the satraps exhibited in the same capital a pomp but little inferior to royal magnificence. Owing to this intimate connection between the chief provinces of Persia and Babylonia, the country lying between this and Susa became the most populous and cultivated in Asia; and a highway was made from Babylon to Susa, which was twenty days’ journey distant, sufficiently commodious for the baggage of an army to be conveyed on it without difficulty. The investigation, however, is involved in greater difficulties as we proceed towards the east beyond Persia, though a principal country to which they traded, that is to say, Persian India, or the present Belur-land, and with the parts adjacent, whence the Babylonians imported many of their most highly prized commodities, afford a clear proof of the direction and extent of this commerce.
The first article which we may confidently assert the Babylonians to have obtained, at least in part, from these countries, were precious stones, the use of which for seal rings was very general amongst them. Ctesias says expressly, that these stones came from India; and that onyxes, sardines, and the other stones used for seals were obtained in the mountains bordering on the sandy desert. The testimonies of modern travellers have proved that the account of this author is entitled to full credit; and that even at the present time the lapis-lazuli is found there in its greatest perfection; and if it be added to this that what Ctesias relates of India undoubtedly refers for the most part to these northern countries, we must consider it probable that the stones in question were found in the mountains of which we are speaking; while with regard to the sapphire of the ancients, that is to say, our lapis-lazuli, I have no doubt that it is a native of this country. A decisive proof is furnished by Theophrastus, a more recent author, but worthy of credit. “Emeralds and jaspers,” says he, “which are used as objects of decoration, come from the desert of Bactria (of Cobi). They are sought for by persons who go thither on horseback at the time of the north wind, which blows away the sand, and so discovers them.” “The largest of the emeralds called Bactrian,” says he, in another place, “is at Tyre, in the temple of Hercules. It forms a tolerably large pillar.” The passage, however, of Ctesias, to which we have referred, as a modern author has justly remarked, contains some indications, which, relatively to onyxes, appear to refer to the Ghat Mountains; since he speaks of a hot country not far from the sea.
The circumstance of large quantities of onyxes coming out of these mountains at the present day, viz., the mountains near Cambaya and Beroach, the ancient Barygaza, must render this opinion so much the more probable, as it was this very part of the Indian coast with which the ancients were most acquainted; and their navigation from the Persian Gulf to these regions, as will be shown hereafter, admits of no doubt. This opinion, however, must not lead us to conclude, that the commerce of Babylon was confined to those countries; for that they were acquainted with the above-mentioned northern districts is equally certain.
Hence also the Babylonians imported Indian dogs. This breed is asserted to be the largest and strongest that exist, and on that account the best suited for hunting wild beasts, even lions, which they will very readily attack. The great fondness felt by the Persians for the pleasures of the chase, by whom it was regarded as a chivalrous exercise, must have increased the value and use of these animals, which soon became even an object of luxury. The Persian nobles were obliged to keep a great number of them, as they formed a necessary part of their domestic economy, and their train; and they were also accustomed to take them with them on their journeys and military expeditions. Thus Xerxes, as we are assured by Herodotus, was followed by an innumerable quantity of dogs, when he marched against Greece; and an example taken from the same writer shows to what a pitch the Persian lords and satraps had carried their luxury in this particular. Tritantæchmes, satrap of Babylon, devoted to the maintenance of these Indian dogs no less than four towns of his government, which were exempted from all other taxes. It is easy to settle the extent of this branch of commerce, admitting, as is reasonable, that they were propagated in the country.
The native country of these animals, according to Ctesias, was that whence precious stones were obtained. And this account of the ancient author has been confirmed by a modern traveller; for Marco Polo, in his account of these regions, has not forgotten to mention large dogs, which were even able to overcome lions.
A third, and no less certain class of productions, which the Persians and Babylonians obtained from this part of the world, were dyes, and amongst them the cochineal, or rather Indian lacca. The most ancient, though not quite accurate description of this insect, and of the tree upon which it settles, is also found in Ctesias. According to him, it is a native of the country near the sources of the Indus, and produces a red, resembling cinnabar. The Indians themselves use it for the purpose of dyeing their garments, to which it gives a colour even surpassing in beauty the dyes of the Persians.
Strabo has preserved to us from Eratosthenes a knowledge of the roads by which the commodities of the Indian districts, bordering on the Persian Empire, were conveyed to its principal cities, and especially to Babylon. The usual high-road, through populous and cultivated regions, first ran in a northerly direction, in order to avoid the predatory tribes which infested the desert between Persia and Media. It continued along the southern part of this desert, as far as one of the most celebrated defiles in Asia, called the Caspian gates, through which it proceeded to Hyrcania and Aria. In this latter country, taking its course along the foot of the high and woody Hyrcanian and Parthian Mountains, the road thence turned northward towards Bactra. This is the same which Alexander followed in his expedition against the Bactrians; and though he left it occasionally to attack the inhabitants of the neighbouring mountains, he always returned to it. In Arrian it bears the name of the great military road.
The great commercial route to India was the same as this as far as Aria. Here, however, it took a different, that is to say, an easterly direction, while the other proceeded northward towards Bactra. Thence it ran to Prophthasia, Arachotus, and Ortospana, where it divided itself into three branches. One of these went due east to the borders of India; perhaps the second had a similar direction, with a little inclination to the south; and the third turned northward towards Bactria and formed the great road through which India had communication with this country and its capital, Bactra. The city must then be regarded as the commercial staple of eastern Asia. Its name belongs to a people who never cease to afford matter for historical details from the time they are first mentioned.
