Thus then have been mentioned those nomad Libyans who live along the sea-coast: and above these inland is the region of Libya which has wild beasts; and above the wild-beast region there stretches a raised belt of sand, extending from Thebes of the Egyptians to the Pillars of Heracles. In this belt at intervals of about ten days' journey there are fragments of salt in great lumps forming hills, and at the top of each hill there shoots up from the middle of the salt a spring of water cold and sweet; and about the spring dwell men, at the furthest limit towards the desert, and above the wild-beast region. First, at a distance of ten days' journey from Thebes, are the Ammonians, whose temple is derived from that of the Theban Zeus, for the image of Zeus in Thebes also, as I have said before, 162 has the head of a ram. These, as it chances, have also other water of a spring, which in the early morning is warm; at the time when the market fills, 163 cooler; when midday comes, it is quite cold, and then they water their gardens; but as the day declines, it abates from its coldness, until at last, when the sun sets, the water is warm; and it continues to increase in heat still more until it reaches midnight, when it boils and throws up bubbles; and when midnight passes, it becomes cooler gradually till dawn of day. This spring is called the fountain of the Sun.
182. After the Ammonians, as you go on along the belt of sand, at an interval again of ten days' journey there is a hill of salt like that of the Ammonians, and a spring of water, with men dwelling about it; and the name of this place is Augila. To this the Nasamonians come year by year to gather the fruit of the date-palms.
183. From Augila at a distance again of ten days' journey there is another hill of salt and spring of water and a great number of fruit-bearing date-palms, as there are also in the other places: and men dwell here who are called the Garmantians, a very great nation, who carry earth to lay over the salt and then sow crops. From this point is the shortest way to the Lotophagoi, for from these it is a journey of thirty days to the country of the Garmantians. Among them also are produced the cattle which feed backwards; and they feed backwards for this reason, because they have their horns bent down forwards, and therefore they walk backwards as they feed; for forwards they cannot go, because the horns run into the ground in front of them; but in nothing else do they differ from other cattle except in this and in the thickness and firmness to the touch 164 of their hide. These Garamantians of whom I speak hunt the "Cave-dwelling" 165 Ethiopians with their four-horse chariots, for the Cave-dwelling Ethiopians are the swiftest of foot of all men about whom we hear report made: and the Cave-dwellers feed upon serpents and lizards and such creeping things, and they use a language which resembles no other, for in it they squeak just like bats.
