Passage 4.36.5
ἐνέμοντο δὲ ἐμοὶ δοκεῖν αἱ τοῦ Νηλέως βοῦς ἐν τῇ ὑπερορίᾳ τὰ πολλά· ὑπόψαμμός τε γάρ ἐστιν ὡς ἐπίπαν ἡ τῶν Πυλίων χώρα καὶ πόαν βουσὶν οὐχ ἱκανὴ τοσαύτην παρασχέσθαι. μαρτυρεῖ δέ μοι καὶ Ὅμηρος ἐν μνήμῃ Νέστορος ἐπιλέγων ἀεὶ βασιλέα αὐτὸν ἠμαθόεντος εἶναι Πύλου.
But in my opinion, the cattle of Neleus generally grazed beyond the borders; for the land of the Pylians is almost entirely sandy and unable to supply enough pasture for cattle. Homer also testifies to this for me, who, whenever mentioning Nestor, always calls him king of "sandy Pylos."
