At Aromata, the Barbaria of the ancients, or the Adel of the moderns, terminates; and the coast of Azania, or Agan, begins. The first mart on this coast is Opone, from which there were exported, besides the usual aromatics and other articles, slaves of a superior description, chiefly for the Egyptian market, and tortoise-shell, also of a superior sort, and in great abundance. There was nothing peculiar in the imports. In this part of his work, the author of the Periplus, mentions and describes the annual voyage between the coast of Africa and India: after enumerating the articles imported from the latter country, which consisted chiefly of corn, rice, butter; oil of Sesanum; cotton, raw and manufactured sashes; and honey from the cane, called sugar; he adds, that "many vessels are employed in this commerce, expressly for the importation of these articles, and others, which have a more distant destination, sell part of their cargoes on this coast, and take in the produce in return." This seems to be the first historical evidence of a commercial intercourse between India and Africa, independent of the voyages of the Arabians; and as the parts from which the ships sailed to India, lay within the limits of the monsoon, it most probably was accomplished by means of it, and directly from land to land, without coasting round by the Gulf of Persia. The ports on the west coast of India, to which the trade was carried on, were Ariake and Barugaza, in Guzerat and Concan. No mart is mentioned after Opone, till we arrive at Rhapta. This place was so named by the Greeks, because the ships employed by the inhabitants were raised from a bottom composed of a single piece of wood, and the sides were sewed to it, instead of being nailed. In order to preserve the sewing, the whole outside was covered over with some of the gums of the country. It is a circumstance worthy of notice, that when the Portuguese first visited this coast, they found ships of exactly the same materials and construction. At Rhapta, the customs were farmed by the merchants of Moosa, though it was subject to one of the princes of Yeman. Arabian commanders and supercargoes were always employed in their ships, from their experience in the navigation: the imports of Rhapta were, lances, principally manufactured at Moosa; axes, knives, awls, and various kinds of glass: the exports were, ivory, inferior to the Aduli ivory, but cheap, and in great abundance; the horns of the rhinoceros, tortoise shell, superior to any of this coast, but not equal to the Indian; and an article called Nauplius, the nature of which is not known. At the period when the Periplus was written, the coast was unknown beyond Rhapta; at this place, therefore, the journal of this voyage terminates; but this place, there is every reason to believe that the author visited in person.
