Passage 9.2.2
ἐπανελθοῦσι δὲ ἐς τὴν λεωφόρον ἐστὶν αὖθις ἐν δεξιᾷ Μαρδονίου λεγόμενον μνῆμα εἶναι. καὶ ὅτι μὲν εὐθὺς ἦν μετὰ τὴν μάχην ἀφανὴς ὁ Μαρδονίου νεκρός, ἔστιν ὡμολογημένον· τὸν δὲ θάψαντα οὐ κατὰ ταὐτά, ὅστις ἦν, λέγουσι· φαίνεται δὲ Ἀρτόντης ὁ Μαρδονίου πλεῖστα μὲν δοὺς Διονυσοφάνει δῶρα ἀνδρὶ Ἐφεσίῳ, δοὺς μέντοι καὶ ἄλλοις Ἰώνων ὡς οὐδὲ ἐκείνοις ἀμελὲς γενόμενον ταφῆναι Μαρδόνιον.
When one returns to the main road, there is again on the right hand side a tomb said to be that of Mardonius. It is agreed that immediately after the battle the body of Mardonius was nowhere to be found; but accounts differ as to who it was that buried him. However, it seems that Artontes son of Mardonius gave abundant gifts to Dionysophanes, a man of Ephesus, and bestowed gifts also upon other Ionians, so that they too did not neglect the burial of Mardonius.
