Passage 9.40.10
προσιόντων δὲ τῇ πόλει πολυάνδριον Θηβαίων ἐστὶν ἐν τῷ πρὸς Φίλιππον ἀγῶνι ἀποθανόντων. ἐπιγέγραπται μὲν δὴ ἐπίγραμμα οὐδέν, ἐπίθημα δʼ ἔπεστιν αὐτῷ λέων· φέροι δʼ ἂν ἐς τῶν ἀνδρῶν μάλιστα τὸν θυμόν· ἐπίγραμμα δὲ ἄπεστιν ἐμοὶ δοκεῖν ὅτι οὐδὲ ἐοικότα τῇ τόλμῃ σφίσι τὰ ἐκ τοῦ δαίμονος ἠκολούθησε.
As one draws near the city, there is a common tomb of the Thebans who fell in the battle against Philip. No epitaph has been inscribed upon it, but it has the figure of a lion set upon it, most fitting indeed to the courage of the men. The absence of an epitaph, in my view, is due to the fact that the fortune granted them by the divine was altogether unsuited to their bravery.
