From these preliminary points we pass on to consider the contents of the work, and these may be conveniently reviewed under the three heads Geography, Navigation, Commerce. In the commentary, which is to accompany the translation, the Geography will be examined in detail. Meanwhile we shall enumerate the voyages which are distinguishable in the _Periplûs_,[2] and the articles of commerce which it specifies. I. VOYAGES MENTIONED IN THE PERIPLUS. I. A voyage from _Berenîkê_, in the south of Egypt, down the western coast of the Red Sea through the Straits, along the coast of Africa, round Cape Guardafui, and then southward along the eastern coast of Africa as far as Rhapta, a place about six degrees south of the equator. II. We are informed of two distinct courses confined to the Red Sea: one from Myos Hormos, in the south of Egypt, across the northern end of the sea to Leukê Kômê, on the opposite coast of Arabia, near the mouth of the Elanitic Gulf, whence it was continued to Mouza, an Arabian port lying not far westward from the Straits; the other from Berenîkê directly down the gulf to this same port III. There is described next to this a voyage from the mouth of the Straits along the southern coast of Arabia round the promontory now called Ras-el-Had, whence it was continued along the eastern coast of Arabia as far as Apologos (now Oboleh), an important emporium at the head of the Persian Gulf, near the mouth of the river Euphrates. IV. Then follows a passage from the Straits to India by three different routes: the first by adhering to the coasts of Arabia, Karmania, Gedrosia, and Indo-Skythia, which terminated at +Barugaza+ (Bharoch), a great emporium on the river +Nammadios+ (the Narmadâ), at a distance of thirty miles from its mouth; the second from +Kanê+, a port to the west of +Suagros+, a great projection on the south coast of Arabia, now Cape Fartaque; and the third from Cape Guardafui, on the African side—both across the ocean by the monsoon to +Mouziris+ and +Nelkunda+, great commercial cities on the coast of Malabar. V. After this we must allow a similar voyage performed by the Indians to Arabia, or by the Arabians to India, previous to the performance of it by the Greeks, because the Greeks as late as the reign of Philomêtôr met this commerce in Sabæa.
