70. Opposed to the Brachmanes there are philosophers, called Pramnæ, contentious people, and fond of argument. They ridicule the Brachmanes as boasters and fools for occupying themselves with physiology and astronomy. Some of the Pramnæ are called Pramnæ of the mountains, others Gymnetæ, others again are called Townsmen and Countrymen. [CAS. 719] The Pramnæ of the mountains wear deer-skins, and carry scrips filled with roots and drugs; they profess to practise medicine by means of incantations, charms, and amulets. The Gymnetæ, as their name imports, are naked and live chiefly in the open air, practising fortitude for the space of thirty-seven years; this I have before mentioned; women live in their society, but without cohabitation. The Gymnetæ are held in singular estimation. 71. The (Pramnæ) Townsmen are occupied in civil affairs, dwell in cities, and wear fine linen, or (as Countrymen they live) in the fields, clothed in the skins of fawns or antelopes. In short, the Indians wear white garments, white linen and muslin, contrary to the accounts of those who say that they wear garments of a bright colour; all of them wear long hair and long beards, plait their hair, and bind it with a fillet. 72. Artemidorus says that the Ganges descends from the Emoda mountains and proceeds towards the south; when it arrives at the city Ganges,[406] it turns to the east, and keeps this direction as far as Palibothra,[407] and the mouth by which it discharges itself into the sea. He calls one of the rivers which flow into it Œdanes,[408] which breeds crocodiles and dolphins. Some other circumstances besides are mentioned by him, but in so confused and negligent a manner that they are not to be regarded. To these accounts may be added that of Nicolaus Damascenus. 73. This writer states that at Antioch, near Daphne,[409] he met with ambassadors from the Indians, who were sent to Augustus Cæsar. It appeared from the letter that several persons were mentioned in it, but three only survived, whom he says he saw. The rest had died chiefly in consequence of the length of the journey. The letter was written in Greek upon a skin; the import of it was, that Porus was the writer, that although he was sovereign of six hundred kings, yet that he highly esteemed the friendship of Cæsar; that he was willing to allow him a passage through his country, in whatever part he pleased, and to assist him in any undertaking that was just.
