36. At the confluence of the Ganges and of another river (the Erannoboas[380]) is situated (the city) Palibothra, in length 80, and in breadth 15 stadia. It is in the shape of a parallelogram, surrounded by a wooden wall pierced with openings through which arrows may be discharged. In front is a ditch, which serves the purpose of defence and of a sewer for the city. The people in whose country the city is situated are the most distinguished of all the tribes, and are called Prasii. The king, besides his family name, has the surname of Palibothrus, as the king to whom Megasthenes was sent on an embassy had the name of Sandrocottus.[381]
Such also is the custom among the Parthians; for all have the name Arsacæ,[382] although each has his peculiar name of Orodes, Phraates, or some other appellation.
37. All the country on the other side of the Hypanis is allowed to be very fertile, but we have no accurate knowledge of it. Either through ignorance or from its remote situation, everything relative to it is exaggerated or partakes of the wonderful. As, for example, the stories of myrmeces (or ants),[383] which dig up gold; of animals and men with peculiar shapes, and possessing extraordinary faculties; of the longevity of the Seres, whose lives exceed the age of two hundred years. They speak also of an aristocratical form of government, consisting of five hundred counsellors, each of whom furnishes the state with an elephant.
According to Megasthenes, the largest tigers are found among the Prasii, almost twice the size of lions, and of such strength that a tame one led by four persons seized a mule by its hinder leg, overpowered it, and dragged it to him. The monkeys are larger than the largest dogs; they are of a white colour, except the face, which is black. The contrary is observed in other places. Their tails are more than two cubits in length. They are very tame, and not of a mischievous disposition. They neither attack people, nor steal.
Stones are found there of the colour of frankincense, and sweeter than figs or honey.
In some places there are serpents of two cubits in length, with membraneous wings like bats. They fly at night, and let fall drops of urine or sweat, which occasions the skin of persons who are not on their guard to putrefy. There are also winged scorpions of great size.
Ebony grows there. There are also dogs of great courage, which do not loose their hold till water is poured into their nostrils: some of them destroy their sight, and the eyes of others even fall out, by the eagerness of their bite. Both a lion and a bull were held fast by one of these dogs. The bull was caught by the muzzle, and died before the dog could be loosened.
38. In the mountainous country is a river, the Silas, on the surface of which nothing will float. Democritus, who had travelled over a large part of Asia, disbelieves this, and Aristotle does not credit it, although atmospheres exist so rare that no bird can sustain its flight in them. Vapours also, which ascend (from some substances), attract and absorb, as it were, whatever is flying over them; as amber attracts straw, and the magnet iron, and perhaps there may be in water a similar power.
As these matters belong to physics and to the question of floating bodies, these must be referred to them. At present we must proceed to what follows, and to the subjects more nearly relating to geography.
39. It is said that the Indians are divided into seven castes. The first in rank, but the smallest in number, are the philosophers. Persons who intend to offer sacrifice, or to perform any sacred rite, have the services of these persons on their private account; but the kings employ them in a public capacity at the time of the Great Assembly, as it is called, where at the beginning of the new year all the philosophers repair to the king at the gate, and anything useful which they have committed to writing, or observed, tending to improve the productions of the earth or animals, or of advantage to the government of the state, is then publicly declared.
