Passage 10.13.9
ἐν κοινῷ δὲ ἀνέθεσαν ἀπὸ ἔργου τοῦ Πλαταιᾶσιν οἱ Ἕλληνες χρυσοῦν τρίποδα δράκοντι ἐπικείμενον χαλκῷ. ὅσον μὲν δὴ χαλκὸς ἦν τοῦ ἀναθήματος, σῶον καὶ ἐς ἐμὲ ἔτι ἦν· οὐ μέντοι κατὰ τὰ αὐτὰ καὶ τὸν χρυσὸν οἱ Φωκέων ὑπελίποντο ἡγεμόνες.
Together as a common dedication from the spoils of the battle at Plataea, the Greeks set up a golden tripod mounted upon a bronze serpent. As for the bronze portion of this offering, it remained intact even down to my own times; however, the Phocian leaders did not leave the gold similarly untouched.
