Passage 5.22.2
παρὰ δὲ τὸ Ἱπποδάμιον καλούμενον λίθου τε βάθρον ἐστὶ κύκλος ἥμισυς καὶ ἀγάλματα ἐπʼ αὐτῷ Ζεὺς καὶ Θέτις τε καὶ Ἡμέρα τὸν Δία ὑπὲρ τῶν τέκνων ἱκετεύουσαι. ταῦτα ἐπὶ μέσῳ τῷ βάθρῳ· οἱ δὲ ἤδη σχῆμα ἀντιτεταγμένων ὅ τε Ἀχιλλεὺς παρέχεται καὶ ὁ Μέμνων ἐπὶ ἑκατέρῳ τοῦ βάθρου τῷ πέρατι ἑκάτερος. ἀνθεστήκασι δὲ καὶ ἄλλος ἄλλῳ κατὰ τὰ αὐτά, ἀνὴρ βάρβαρος ἀνδρὶ Ἕλληνι, Ὀδυσσεὺς μὲν Ἑλένῳ, ὅτι οὗτοι μάλιστα ἐπὶ σοφίᾳ δόξαν ἐν ἑκατέρῳ τῷ στρατεύματι εἰλήφεσαν, Μενελάῳ δὲ κατὰ τὸ ἔχθος τὸ ἐξ ἀρχῆς Ἀλέξανδρος, Διομήδει δὲ Αἰνείας καὶ τῷ Τελαμῶνος Αἴαντι Δηίφοβος.
Near what is called the Hippodameion is a semicircular stone pedestal upon which stand statues of Zeus, Thetis, and Eos, who are supplicating Zeus on behalf of their children. These figures occupy the middle of the pedestal. At either end of the pedestal Achilles and Memnon are portrayed already poised against each other. Others similarly stand opposed in pairs, barbarian against Greek: Odysseus facing Helenus, as both had attained the greatest reputation for wisdom among their respective armies; Alexander positioned against Menelaus because of their ancient enmity; Aeneas opposite Diomedes; and Deiphobus opposite Ajax, son of Telamon.
