In the extract we have already given from Agatharcides respecting Arabia, he expressly mentions that the Gerrheans and Sabeans are the centre of all the commerce that passes between Asia and Europe, and that these are the nations which have enriched the Ptolemais: this statement, taken in conjunction with the fact that his description of the coast of the Red Sea reaches no farther than Sabaea on the one side, and Ptolemais Theron on the other, seems decisive of the truth of the opinion, that in the time of Philometor the Egyptians did not trade directly to India. It may be proper to add, that in the extracts from Agatharcides, given by Photius, it is expressly mentioned that ships from India were met with by the Egyptian ships in the ports of Sabaea. The particulars of this trade between India and Egypt, by means of the Arabians, will be afterwards detailed, and its great antiquity traced and proved; at present we have alluded to it merely to bear us out in our position, that Indian ships, laden with Indian commodities, frequenting the ports of Sabaea, and those ports being described by Agatharcides as the limits of his knowledge of this coast of the Red Sea, we are fully justified in concluding, that, in the reign of Philometor, there was not only no direct trade to India, but no inducement to such trade; and that 146 years after the death of Alexander, the Greek sovereigns of Egypt had done little to complete what that monarch had projected, and in part accomplished by the navigation of Nearchus--the communication by sea between Alexandria and India.
