§4.48.1Ἴστρος μέν, ἐὼν μέγιστος ποταμῶν πάντων τῶν ἡμεῖς ἴδμεν, ἴσος αἰεὶ αὐτὸς ἑωυτῷ ῥέει καὶ θέρεος καὶ χειμῶνος, πρῶτος δὲ τὸ ἀπʼ ἑσπέρης τῶν ἐν τῇ Σκυθικῇ ῥέων κατὰ τοιόνδε μέγιστος γέγονε· ποταμῶν καὶ ἄλλων ἐς αὐτὸν ἐκδιδόντων
The Ister, being the greatest of all rivers we know, flows always equal to itself both in summer and in winter; and, flowing first from the west among the rivers in Scythia, it has become the greatest for the following reason: because other rivers also discharge into it.
§4.48.2εἰσὶ δὴ οἵδε οἱ μέγαν αὐτὸν ποιεῦντες, διὰ μέν γε τῆς Σκυθικῆς χώρης πέντε μὲν οἱ ῥέοντες, τὸν τε Σκύθαι Πόρατα καλέουσι Ἑλλήνες δὲ Πυρετόν, καὶ ἄλλος Τιάραντος καὶ Ἄραρος τε καὶ Νάπαρις καὶ Ὀρδησσός.
Indeed, these are the ones that make it great: flowing on the one hand through the Scythian land, there are five, namely the one which the Scythians call Porata and the Greeks Pyretos, and another, the Tiarantus, and the Ararus, the Naparis, and the Ordessus.
§4.48.3ὁ μὲν πρῶτος λεχθεὶς τῶν ποταμῶν μέγας καὶ πρὸς ἠῶ ῥέων ἀνακοινοῦται τῷ Ἴστρῳ τὸ ὕδωρ, ὁ δὲ δεύτερος λεχθεὶς Τιάραντος πρὸς ἑσπέρης τε μᾶλλον καὶ ἐλάσσων, ὁ δὲ δὴ Ἄραρός τε καὶ ὁ Νάπαρις καὶ ὁ Ὀρδησσὸς καὶ μέσου τούτων ἰόντες ἐσβάλλουσι ἐς τὸν Ἴστρον.
The first-mentioned of these rivers is large, and flowing towards the east, mingles its water with the Ister; the second-mentioned, the Tiarantus, is more to the west and is smaller; and the Ararus, the Naparis, and the Ordessus, going between these, empty into the Ister.
