Beyond is the region of Sirbitum, at which the mountains terminate,[737] and which by some writers is said to contain the maritime Æthiopians, the Nisacæthæ, and the Nisyti, a word which signifies “men with three or four eyes,”—not that the people really have that conformation, but because they are remarkable for the unerring aim of their arrows. On that side of the Nile which extends along the borders of the Southern Ocean beyond the Greater Syrtes,[738] Dalion says that the people, who use rain-water only, are called the Cisori, and that the other nations are the Longompori, distant five days’ journey from the Œcalices, the Usibalci, the Isbeli, the Perusii, the Ballii, and the Cispii, the rest being deserts, and inhabited by the tribes of fable only. In a more westerly direction are the Nigroæ, whose king has only one eye, and that in the forehead, the Agriophagi,[739] who live principally on the flesh of panthers and lions, the Pamphagi,[740] who will eat anything, the Anthropophagi, who live on human flesh, the Cynamolgi,[741] a people with the heads of dogs, the Artabatitæ, who have four feet, and wander about after the manner of wild beasts; and, after them, the Hesperiæ and the Perorsi, whom we have already spoken[742] of as dwelling on the confines of Mauritania. Some tribes, too, of the Æthiopians subsist on nothing but locusts,[743] which are smoke-dried and salted as their provision for the year; these people do not live beyond their fortieth year. M. Agrippa was of opinion that the length[744] of the whole country of the Æthiopians, including the Red Sea, was two thousand one hundred and seventy miles, and its breadth, including Upper Egypt, twelve hundred and ninety-seven. Some authors again have made the following divisions of its length; from Meroë to Sirbitum eleven days’ sail, from Sirbitum to the Dabelli fifteen days’, and from them to the Æthiopian Ocean six days’ journey. It is agreed by most authors, that the distance altogether, from the ocean[745] to Meroë, is six hundred and twenty-five miles, and from Meroë to Syene, that which we have already mentioned. Æthiopia lies from south-east to south-west. Situate as it is, in a southern hemisphere, forests of ebony are to be seen of the brightest verdure; and in the midst of these regions there is a mountain of immense height, which overhangs the sea, and emits a perpetual flame. By the Greeks this mountain is called Theon Ochema,[746] and at a distance of four days’ sail from it is a promontory, known as Hesperu Ceras,[747] upon the confines of Africa, and close to the Hesperiæ, an Æthiopian nation. There are some writers who affirm that in these regions there are hills of a moderate height, which afford a pleasant shade from the groves with which they are clad, and are the haunts of Ægipans[748] and Satyrs.
