§4.31.1περὶ δὲ τῶν πτερῶν τῶν Σκύθαι λέγουσι ἀνάπλεον εἶναι τὸν ἠέρα, καὶ τούτων εἵνεκα οὐκ οἷοί τε εἶναι οὔτε ἰδεῖν τὸ πρόσω τῆς ἠπείρου οὔτε διεξιέναι, τήνδε ἔχω περὶ αὐτῶν γνώμην· τὰ κατύπερθε ταύτης τῆς χώρης αἰεὶ νίφεται, ἐλάσσονι δὲ τοῦ θέρεος ἢ τοῦ χειμῶνος, ὥσπερ καὶ οἰκός.
Concerning the feathers, which the Scythians say fill the air, and that because of them it is impossible either to see further into the continent or to pass through it, I hold this opinion about them: the regions upper from this country are always snowed upon, less in summer than in winter, as is indeed natural.
§4.31.2ἤδη ὦν ὅστις ἀγχόθεν χιόνα ἁδρὴν πίπτουσαν εἶδε οἶδε τὸ λέγω· ἔοικε γὰρ ἡ χιὼν πτεροῖσι καὶ διὰ τὸν χειμῶνα τοῦτον ἐόντα τοιοῦτον ἀνοίκητα τὰ πρὸς βορέην ἐστὶ τῆς ἠπείρου ταύτης.
Now, anyone who has seen thick snow falling close at hand already knows what I mean; for snow resembles feathers, and because of this winter being so severe, the northern parts of this continent are uninhabitable.
τὰ ὦν πτερὰ εἰκάζοντας τὴν χιόνα τοὺς Σκύθας τε καὶ τοὺς περιοίκους δοκέω λέγειν.
I think, therefore, that the Scythians and their neighbours speak of 'feathers' as a figurative way of describing the snow.
ταῦτα μέν νυν τὰ λέγεται μακρότατα εἴρηται.
These things, then, which are told of the most distant regions, have been related.
