5. Stories circulated for the purpose of exalting the fame [of eminent persons] are not received with equal favour by all; the object of the inventors was flattery rather than truth; [CAS. 505] they transferred, for example, the Caucasus to the mountains of India, and to the eastern sea, which approaches close to them, from the mountains situated above Colchis, and the Euxine Sea. These are the mountains to which the Greeks give the name of Caucasus, and are distant more than 30,000 stadia from India. Here they lay the scene of Prometheus and his chains, for these were the farthest places towards the east with which the people of those times were acquainted. The expeditions of Bacchus and of Hercules against the Indi indicate a mythological story of later date, for Hercules is said to have released Prometheus a thousand years after he was first chained to the rock. It was more glorious too for Alexander to subjugate Asia as far as the mountains of India, than to the recess only of the Euxine Sea and the Caucasus. The celebrity, and the name of the mountain, together with the persuasion that Jason and his companions had accomplished the most distant of all expeditions when they had arrived in the neighbourhood of the Caucasus, and the tradition that Prometheus had been chained on Caucasus at the extremity of the earth, induced writers to suppose that they should gratify the king by transferring the name of the mountain to India. 6. The highest points of the actual Caucasus are the most southerly, and lie near Albania, Iberia, the Colchi, and Heniochi. They are inhabited by the people whom I have mentioned as assembling at Dioscurias. They resort thither chiefly for the purpose of procuring salt. Of these tribes some occupy the heights; others live in wooded valleys, and subsist chiefly on the flesh of wild animals, wild fruits, and milk. The heights are impassable in winter; in summer they are ascended by fastening on the feet shoes as wide as drums, made of raw hide, and furnished with spikes on account of the snow and ice. The natives in descending with their loads slide down seated upon skins, which is the practice in Media, Atropatia, and at Mount Masius in Armenia, but there they fasten circular disks of wood with spikes to the soles of their feet. Such then is the nature of the heights of Caucasus. 7. On descending to the country lying at the foot of these heights the climate is more northerly, but milder, for the land below the heights joins the plains of the Siraces. There are some tribes of Troglodytæ who inhabit caves on account of the cold. There is plenty[967] of grain to be had in the country. Next to the Troglodytæ are Chamæcœtæ,[968] and a tribe called Polyphagi (the voracious), and the villages of the Eisadici, who are able to cultivate the ground because they are not altogether exposed to the north.
