The evidence of the land trade between Arabia and India, from a very early period, is equally clear and decisive: Petra, the capital of Arabia Petrea, was the centre of this trade. To it the caravans, in all ages, came from Minea, in the interior of Arabia, and from Gherra, in the Gulf of Persia,--from Hadraumaut, on the Ocean, and some even from Sabaea. From Petra, the trade again spread in every direction--to Egypt, Palestine, and Syria, through Arsinoe, Gaza, Tyre, Jerusalem, Damascus, and other places of less consequence, all lying on routes terminating in the Mediterranean.
The Gherrheans, who were a Babylonian colony settled in that part of Arabia, which extends along the south coast of the Persian Gulf, are the earliest conductors of caravans upon record. They are first mentioned by Agatharcides, who compares their wealth with that of the Sabeans, and describes them as the agents for all the precious commodities of Asia and Europe: he adds that they brought much wealth into Syria, and furnished a variety of articles, which were afterwards manufactured or resold by the Phoenicians. But the only route by which Syria and Phoenicia could have been supplied by them, was through Petra. The particular articles with which their caravans were loaded, according to Strabo, were the produce of Arabia, and the spices of India. Besides the route of their caravans, across the whole peninsula to Petra, it appears that they sometimes carried their merchandize in boats up the Euphrates to Babylon, or even 240 miles higher up, to Thapsacus, and thence dispersed it in all directions by land.
The exact site of the country of the Mineans cannot be certainly fixed; but it is probable that it was to the south of Hedjaz, to the north of Hadraumaut, and to the eastward of Sabaea. According to Strabo, their caravans passed in seventy days from Hadraumaut to Aisla, which was within ten miles of Petra. They were laden with aloes, gold, myrrh, frankincense, and other aromatics.
We can but faintly and obscurely trace the fluctuations in the trade of Petra, in the remote periods of history. We know that Solomon was in possession of Idumea, but whether it was subdued by Nebuchadnezzar is doubtful. This sovereign, however, seems to have formed some plan of depriving the Gherrheans of the commerce of the Gulf of Persia. He raised a mound to confine the waters of the Tigris: he built a city to stop the incursions of the Arabs, and opened a communication between the rivers Tigris and Euphrates. After this there is no account of Idumea till some years subsequent to the death of Alexander the Great: at this period two expeditions were sent into it against its capital, Petra, by Antigonus, both of which were unsuccessful. These expeditions were undertaken about the years 308 and 309 before Christ. The history of Idumea, from this period, is better ascertained: harassed by the powerful kingdoms of Syria and Egypt,--contiguous to both of which it lay,--it seems to have been governed by princes of its own, who were partly independent, and partly under the influence of the monarchs of Syria and Egypt. About sixty-three years before Christ, Pompey took Petra; and, from that period, the sovereigns of Idumea were tributary to the Romans. This city, however, still retained its commerce, and was in a flourishing condition, as we are informed by Strabo, on the authority of his friend Athenedorus, who visited it about thirty-six years after it. He describes it as built on a rock, distinguished, however, from all the rocks in that part of Arabia, from being supplied with an abundant spring of water. Its natural position, as well as art, rendered it a fortress of importance in the desert. He represents the people as rich, civilized, and peaceable; the government as regal, but the chief power as lodged in a minister selected by the king, who had the title of the king's brother. Syllaeus, who betrayed Elius Gallus, appears to have been a minister of this description.
The next mention that occurs of the trade of Petra is in the Periplus of the Erythrean Sea, the date of which, though uncertain, there is good reason to fix in Nero's reign. According to this work, Leuke Kome, at the mouth of the Elanitic Gulf, was the point of communication with Petra, the capital of the country, the residence of Malachus, the king of the Nabathians. "Leuke Kome, itself, had the rank of a mart in respect to the small vessels which obtained their cargoes in Arabia, for which reason there was a garrison placed in it, under the command of a centurion, both for the purpose of protection, and in order to collect a duty of twenty-five in the hundred." In the reign of Trajan, Idumea was reduced into the form of a Roman province, by one of his generals; after this time it not does fall within our plan to notice it, except merely to state, that its subjection does not seem to have been complete or permanent, for during the latter empire, there were certainly sovereigns of this part of Arabia, in some degree independent, whose influence and alliance were courted by the Romans and Persians, whenever a war was about to commence between these two powers.
From this sketch of the trade of the Arabians from the earliest period, we may conclude, in the first place, that when navigation was in its infancy, it was confined, or almost entirely so, to a land trade carried on by caravans; and that Petra was the centre to which these caravans tended from the east and the south, bringing with them from the former the commodities of India, and from the latter the commodities of the more fertile part of Arabia. From Petra, all these goods were again transported by land to the shores of the Mediterranean and to Egypt. In the second place, when navigation became more commonly known and practised, (and there is good reason to believe that it was known and practised among the Arabians, especially those near the Persian Gulf, at a very early period,) a portion of the Indian commodities, which before had been carried by land to Petra were brought by sea to Sabaea. It appears that in the age of Agatharcides, the monopoly of the trade between India and Europe by this route was wholly possessed by the Sabeans; that, in order to evade the effects of this monopoly, the Greeks of Egypt found their way to Aden and Hadraumaut, in Arabia, and to Mosullon on the coast of Africa. Here they met with other Arabians, who at this time also traded to India, and sold them Indian goods at a cheaper rate. And, lastly, we have seen that these ports on the southern coast of Arabia, and on the coast of Africa, were frequented by the merchants of Egypt, till, by the discovery of the monsoon, their ships were enabled to sail directly to India. It is undoubtedly true that before this discovery, single ships occasionally reached India by adhering to the coast all the way, but the direct communication was very rare. After the nature of the monsoon was thoroughly understood, and it was ascertained that complete dependence could be placed on its steadiness and regularity, and that by its change, the ships could be brought as safely and quickly back from India, as they had reached it, the ancients, who at first only ventured to the mouth of the Indus, gradually made their way down the western coast of the Indian peninsula.
The Periplus of the Erythrean Sea, a work which has been frequently referred to, is rich in materials to illustrate the geographical knowledge and the commercial enterprize of the ancients in the part of the world to which it relates. We have already assigned its date to the age of Nero. Our limits will prevent us from giving a full account of this work; we shall therefore, in the first place, give a short abstract of the geographical knowledge which it displays, and in the next place, illustrate from it, the nature of the commerce carried on, on the Red Sea, the adjacent coasts of Africa and Arabia, and the ports of India, which are noticed in it.
At the time of Strabo, the geography of the ancients did not extend, on the eastern coast of Africa, further to the south than a promontory called Noti Cornu, (the Southern Horn,) which seems to have been in about 12-1/2 degrees north latitude. Beyond this an arid coast, without ports or fresh water, arrested the progress of navigation; but it appears by the Periplus, that this promontory was now passed, and commerce had extended to the port of Rhapta and the isle of Menutias, which are supposed to correspond with Babel Velho and the island of Magadoxa. The author of the Periplus, who seems to have been a merchant personally acquainted with most of the places he describes, had heard of, but not visited the promontory Prasum: he represents the ocean beyond Rhapta as entirely unknown, but as believed to continue its western direction, and after having washed the south coast of Ethiopia, to join the Western Ocean. The whole of the west coast of India, from the Indus to Trapobane, is minutely described in the Periplus. Some of the particulars of the manners and customs of the inhabitants coincide in a striking manner with those of the present day; this observation applies, among other points, to the pirates between Bombay and Goa.
Dr. Vincent, in his learned commentary on the Periplus, gives it as his opinion, that the author of the Periplus never went further than Nelkundah himself, that is, to the boundary between the provinces of Canara and Malabar. The east coast of the Indian peninsula is not traced so minutely nor so accurately as the west coast, though there are names and descriptions in the Periplus, from which it may fairly be inferred, that the author alludes to Cavary, Masulapatam, Calingapatam, Coromandel, and other places and districts of this part of India. The countries beyond the Ganges, the Golden Chersonese, and the countries towards China, are very obscurely noticed in the Periplus, though the information he gives respecting the trade carried on in these parts is much more minute and accurate. His description of the direction of the coast of India, is on the whole, surprisingly consonant to truth: according to him, it tends from north to south, as far as Colchos (Travancore); at this place it bends to the east, and afterwards to the north; and then again a little to the east, as far as the Ganges. He is the first author in whom can clearly be traced the name of the great southern division of India: his term is Dachanabades,--Dachan signifying south, and abad a city; and Decan is still the general name of all the country to the south of Baroche, the boundary assigned by the author. The particulars he mentions of the bay of Cutch, of Cambay, of Baroche, and of the Ghauts, may also be mentioned as proofs of his accuracy with respect to those parts of India, which he visited in person.
Having thus given a sketch of the geographical knowledge contained the Periplus, we shall next attend to the commercial information which it conveys. As this work is divided into two distinct parts, the first comprising the coast of the Red Sea, and of Africa, from Myos Hormos on the former, to Rhapta in the latter: and the second part, beginning at the same place, and including the whole coast of Arabia, both that which lies on the Red Sea, and that which lies on the Ocean, and then stretching from the Gulf of Persia to Guzerat, describing the coast of Malabar, as far as Ceylon, we shall, in our abstract of the commercial intelligence it contains, enumerate the principal imports and exports of the most frequented marts in Africa, (including the Red Sea,) Arabia, and India.
