Passage 6.5.1
ὁ δὲ ἐπὶ τῷ βάθρῳ τῷ ὑψηλᾷ Λυσίππου μέν ἐστιν ἔργον, μέγιστος δὲ ἁπάντων ἐγένετο ἀνθρώπων πλὴν τῶν ἡρώων καλουμένων καὶ εἰ δή τι ἄλλο ἦν πρὸ τῶν ἡρώων θνητὸν γένος· ἀνθρώπων δὲ τῶν καθʼ ἡμᾶς οὗτός ἐστιν ὁ μέγιστος Πουλυδάμας Νικίου.
The statue upon the high pedestal is a work of Lysippus, representing the greatest of all men, excepting only those called heroes, and whatever mortal race may have existed before the heroes. Among the men of our own time, this Polydamas, son of Nicias, is the greatest.
