15.1.11

τὴν Ἰνδικὴν περιώρικεν ἀπὸ μὲν τῶν ἄρκτων τοῦ Ταύρου τὰ ἔσχατα ἀπὸ τῆς Ἀριανῆς μέχρι τῆς ἑῴας θαλάττης, ἅπερ οἱ ἐπιχώριοι κατὰ μέρος Παροπάμισόν τε καὶ Ἠμωδὸν καὶ Ἴμαον καὶ ἄλλα ὀνομάζουσι, Μακεδόνες δὲ Καύκασον· ἀπὸ δὲ τῆς ἑσπέρας ὁ Ἰνδὸς ποταμός· τὸ δὲ νότιον καὶ τὸ προσεῷον πλευρόν, πολὺ μείζω τῶν ἑτέρων ὄντα, προπέπτωκεν εἰς τὸ Ἀτλαντικὸν πέλαγος, καὶ γίνεται ῥομβοειδὲς τὸ τῆς χώρας σχῆμα τῶν μειζόνων πλευρῶν ἑκατέρου πλεονεκτοῦντος παρὰ τὸ ἀπεναντίον πλευρὸν καὶ τρισχιλίοις σταδίοις, ὅσων ἐστὶ τὸ κοινὸν ἄκρον τῆς τε ἑωθινῆς παραλίας καὶ τῆς μεσημβρινῆς, ἔξω προπεπτωκὸς ἐξ ἴσης ἐφʼ ἑκάτερον παρὰ τὴν ἄλλην ᾐόνα. τῆς μὲν οὖν ἑσπερίου πλευρᾶς ἀπὸ τῶν Καυκασίων ὀρῶν ἐπὶ τὴν νότιον θάλατταν στάδιοι μάλιστα λέγονται μύριοι τρισχίλιοι παρὰ τὸν Ἰνδὸν ποταμὸν μέχρι τῶν ἐκβολῶν αὐτοῦ, ὥστʼ ἀπεναντίον ἡ ἑωθινὴ προσλαβοῦσα τοὺς τῆς ἄκρας τρισχιλίους ἔσται μυρίων καὶ ἑξακισχιλίων σταδίων. τοῦτο μὲν οὖν πλάτος τῆς χώρας τό τʼ ἐλάχιστον καὶ τὸ μέγιστον. μῆκος δὲ τὸ ἀπὸ τῆς ἑσπέρας ἐπὶ τὴν ἕω· τούτου δὲ τὸ μὲν μέχρι Παλιβόθρων ἔχοι τις ἂν βεβαιοτέρως εἰπεῖν· καταμεμέτρηται γὰρ σχοινίοις καὶ ἔστιν ὁδὸς βασιλικὴ σταδίων μυρίων· τὰ δʼ ἐπέκεινα στοχασμῷ λαμβάνεται διὰ τῶν ἀνάπλων τῶν ἐκ θαλάττης διὰ τοῦ Γάγγου ποταμοῦ μέχρι Παλιβόθρων· εἴη δʼ ἄν τι σταδίων ἑξακισχιλίων. ἔσται δὲ τὸ πᾶν ᾗ βραχύτατον μυρίων ἑξακισχιλίων, ὡς ἔκ τε τῆς ἀναγραφῆς τῶν σταθμῶν τῆς πεπιστευμένης μάλιστα λαβεῖν Ἐρατοσθένης φησί, καὶ ὁ Μεγασθένης οὕτω συναποφαίνεται, Πατροκλῆς δὲ χιλίοις ἔλαττον φησί. τούτῳ δὴ πάλιν τῷ διαστήματι προστεθὲν τὸ τῆς ἄκρας διάστημα τὸ προπῖπτον ἐπὶ πλέον πρὸς τὰς ἀνατολάς, οἱ τρισχίλιοι στάδιοι ποιήσουσι τὸ μέγιστον μῆκος· ἔστι δὲ τοῦτο τὸ ἀπὸ τῶν ἐκβολῶν τοῦ Ἰνδοῦ ποταμοῦ παρὰ τὴν ἑξῆς ᾐόνα μέχρι τῆς λεχθείσης ἄκρας καὶ τῶν ἀνατολικῶν αὐτῆς τερμόνων· οἰκοῦσι δʼ ἐνταῦθα οἱ Κωνιακοὶ καλούμενοι.

The boundaries of India, on the north, from Ariana to the Eastern Sea, are the extremities of Taurus, to the several parts of which the natives give, besides others, the names of Paropamisus, Emodus, and Imaus, but the Macedonians call them Caucasus; on the west, the river Indus; the southern and eastern sides, which are much larger than the others, project towards the Atlantic Sea, and the figure of the country becomes rhomboïdal, each of the greater sides exceeding the opposite by 3000 stadia; and this is the extent of the extremity, common to the eastern and southern coast, and which projects beyond the rest of that coast equally on the east and south.
The western side, from the Caucasian mountains to the Southern Sea, is estimated at 13,000 stadia, along the river Indus to its mouth; wherefore the eastern side opposite, with the addition of the 3000 stadia of the promontory, will be 16,000 stadia in extent. This is both the smallest and greatest breadth of India. The length is reckoned from west to east. The part of this extending (from the Indus) as far as Palibothra we may describe more confidently; for it has been measured by Schoeni, and is a royal road of 10,000 stadia. The extent of the parts beyond depends upon conjecture derived from the ascent of vessels from the sea by the Ganges to Palibothra. This may be estimated at 6000 stadia.
The whole, on the shortest computation, will amount to 16,000 stadia, according to Eratosthenes, who says that he took it from the register of the Stathmi (or the several stages from place to place), which was received as authentic, and Megasthenes agrees with him. But Patrocles says, that the sum of the whole is less by 1000 stadia. If again we add to this distance the extent of the extremity which advances far towards the east, the greatest length of India will be 3000 stadia; this length is reckoned from the mouths of the river Indus along the coast, in a line with the mouths to the abovementioned extremity and its eastern limits. Here the people called Coniaci live.
