Passage 3.4.10
ἐπεὶ δὲ Πλαταιᾶσι Μαρδόνιός τε ἔπεσεν ἐν τῇ μάχῃ καὶ ἀπώλοντο οἱ βάρβαροι, τὴν γυναῖκα ὁ Παυσανίας ἀπέστειλεν ἐς τὴν Κῶν κόσμον τε ὃν ἐποιήσατο ὁ Πέρσης αὐτῇ καὶ τὴν ἄλλην ἀγομένην κατασκευήν. Μαρδονίου τε οὐκ ἠθέλησεν ὁ Παυσανίας αἰσχῦναι τὸν νεκρὸν κατὰ τὴν παραίνεσιν τοῦ Αἰγινήτου Λάμπωνος.
When Mardonius fell in battle at Plataea and the barbarians were defeated, Pausanias sent the woman to Cos along with the jewelry which the Persian had made for her and all other belongings she possessed. Pausanias also refused to dishonor the corpse of Mardonius, despite the suggestion made by Lampon of Aegina.
