Beyond these people, and at the very extremity of the mountains, the Trispithami and the Pygmies are said to exist; two races which are but three spans in height, that is to say, twenty-seven inches only. They enjoy a salubrious atmosphere, and a perpetual spring, being sheltered by the mountains from the northern blasts; it is these people that Homer[65] has mentioned as being warred upon by cranes. It is said, that they are in the habit of going down every spring to the sea-shore, in a large body, seated on the backs of rams and goats, and armed with arrows, and there destroy the eggs and the young of those birds; that this expedition occupies them for the space of three months, and that otherwise it would be impossible for them to withstand the increasing multitudes of the cranes. Their cabins, it is said, are built of mud, mixed with feathers and egg-shells. Aristotle says, that they dwell in caves; but, in all other respects, he gives the same details as other writers. Isigonus informs us, that the Cyrni, a people of India, live to their four hundredth year; and he is of opinion that the same is the case also with the Æthiopian Macrobii, the Seræ, and the inhabitants of Mount Athos. In the case of these last, it is supposed to be owing to the flesh of vipers,[66] which they use as food; in consequence of which, they are free also from all noxious animals, both in their hair and their garments. According to Onesicritus, in those parts of India where there is no shadow, the bodies of men attain a height of five cubits and two palms, and their life is prolonged to one hundred and thirty years; they die without any symptoms of old age, and just as if they were in the middle period of life. Ctesias mentions a tribe known by the name of Pandore, whose locality is in the valleys, and who live to their two hundredth year; their hair is white in youth, and becomes black in old age. On the other hand, there are some people joining up to the country of the Macrobii, who never live beyond their fortieth year, and there is never more than one child in a family. This circumstance is also mentioned by Agatharchides, who states, in addition, that they live on locusts, and are very swift of foot. Clitarchus and Megasthenes give these people the name of Mandi, and enumerate as many as three hundred villages which belong to them. Their women marry in the seventh year of their age, and become old at forty. Artemidorus states that in the island of Taprobana, life is prolonged to an extreme length, while, at the same time, the body is exempt from weakness. Among the Calingæ, a nation also of India, the women marry at five years of age, and do not live beyond their eighth year. In other places again, there are men born with long hairy tails, and of remarkable swiftness of foot; while there are others that have ears so large as to cover the whole body.[67]
