Philostratus, Life of Apollonius of Tyana
1.39.2 (tr. Christopher P. Jones):
When much money had once come to the king from his subjects, he opened his treasury to show the Master his money and to tempt him with love of wealth. But he admired nothing he was shown, saying only, "This is money to you, Majesty, but rubbish to me."
χρημάτων δὲ ἐκ τῆς ὑπηκόου φοιτησάντων ποτὲ ἀθρόων, ἀνοίξας τοὺς θησαυροὺς ἐδείκνυ τῷ ἀνδρὶ τὰ χρήματα, ὑπαγόμενος αὐτὸν ἐς ἐπιθυμίαν πλούτου. ὁ δὲ οὐδὲν ὧν εἶδε θαυμάσας "σοὶ ταῦτα," ἔφη "ὦ βασιλεῦ, χρήματα, ἐμοὶ δὲ ἄχυρα."
= "chaff, bran, husks left after threshing or grinding" (Liddell-Scott-Jones).
