Pliny: Position, Boundaries, and Physical Characteristics of India
BOOK VI. c. 17 (21). But where the chain of Hemodus rises the communities are settled, and the nations of India, which begin there, adjoin not only the eastern sea but also the southern, which we have already mentioned under the name of the Indian Ocean. That part which faces the east runs in a straight line to the bend where the Indian Ocean begins, and measures 1875 miles. Then from this bend to the south up to the river Indus, which forms the western boundary of India, the distance, as given by Eratosthenes, is 2475 miles. But many authors have represented the total length of its coast as being a sail of forty days and forty nights, and its length from north to south as being 2850 miles. Agrippa has estimated its length at 3300 miles, and its breadth at 2300. Poseidonios has measured it from north-east to south-east, placing it opposite to Gaul, which he was measuring from north-west to south-west, making the whole of India lie to west of Gaul. Hence he has shown by undoubted proofs that India being opposite to Gaul must be refreshed by the blowing of the west wind, and have in consequence a salubrious climate. Here the appearance of the heavens is entirely changed, and the stars rise differently; there are two summers in the year, and two harvests having winter between them, while the Etesian winds are prevalent; and during our winter the breezes there are light and the seas navigable. In this country the nations and cities are numberless should one attempt to reckon them all up. It was opened up to our knowledge not only by the arms of Alexander the Great and of the kings who succeeded him, Seleucus and Antiochus, as well as by their admiral Patrokles who sailed round even into the Hyrcanian and Caspian seas, but also by certain Greek authors, who resided with Indian kings, such as Megasthenes, and Dionysius who was sent by Philadelphus, and have thus informed us of the power and resources of the Indian nations. However, there is no room for a careful examination of their statements, they are so diverse and incredible. The companions of Alexander the Great have written that in that tract of India, which he subdued, there were 5000 towns, none less than Cos--that its nations were nine in number--that India was the third part of all the world, and that the multitude of its inhabitants was past reckoning. For this there was probably a good reason, since the Indians almost alone among the nations have never emigrated from their own borders. Their kings from Father Bacchus down to Alexander the Great are reckoned at 153 over a space of 6451 years and three months. The vast size of their rivers fills the mind with wonder. It is recorded that Alexander on no day had sailed on the Indus less than 600 stadia, and was unable to reach its mouth in less than five months and a few days, and yet it appears that it is smaller than the Ganges. Seneca, who was our fellow-citizen and composed a treatise on India, has given the number of its rivers at 60, and that of its nations at 118. It would be as great a difficulty should we attempt to enumerate its mountains. The chains of Imavos, Hemodus, Paropanisus, and Caucasus are mutually connected, and from their base the whole country sinks down into a plain of immense extent and bears a great resemblance to Egypt. But that our account of the geography of these regions may be better understood, we shall tread in the steps of Alexander the Great, whose marches were measured by Diognetes and Baeton.
BooK II. c. 73 (75). In the same way they inform us that in the town of Syene, which is 5000 stadia south of Alexandria, no shadow is cast at noon on the day of the solstice, and that a well dug for the purpose of the experiment was completely illuminated, from which it appears that the sun is vertical at that place, and Onesicritus writes that in India this is the case at that time at the river Hypasis. . . . In the country of the Oretes, a people of India, is the mountain Maleus, near which shadows in the summer are cast to the south and in winter to the north. The stars of the Great Bear are visible there for fifteen days only. In India also, at Patala, a celebrated port, the sun rises on the right hand and the shadows fall to the south. It was observed, while Alexander was staying there the seven stars of the Bear were seen only at the early part of the evening. Onesicritus, one of his generals, states that in those parts of India where there are no shadows the Bear is not seen; these places, he says, are called 'ascia,' and time there is not reckoned by hours.
C. 108 (112). One part of the earth . . . stretches out to the greatest extent from east to west, that is, from India to the Pillars of Hercules at Gades, being a distance of 8578 miles according to Artemidorus, but according to Isidorus 9818 miles.
Book VI. c. 16 (18). This nation (the Bactrian) lies at the back of Mount Paropanisus over against the sources of the river Indus.
