Passage 1.25.2
πρὸς δὲ τῷ τείχει τῷ Νοτίῳ γιγάντων, οἳ περὶ Θρᾴκην ποτὲ καὶ τὸν ἰσθμὸν τῆς Παλλήνης ᾤκησαν, τούτων τὸν λεγόμενον πόλεμον καὶ μάχην πρὸς Ἀμαζόνας Ἀθηναίων καὶ τὸ Μαραθῶνι πρὸς Μήδους ἔργον καὶ Γαλατῶν τὴν ἐν Μυσίᾳ φθορὰν ἀνέθηκεν Ἄτταλος, ὅσον τε δύο πηχῶν ἕκαστον. ἕστηκε δὲ καὶ Ὀλυμπιόδωρος, μεγέθει τε ὧν ἔπραξε λαβὼν δόξαν καὶ οὐχ ἥκιστα τῷ καιρῷ, φρόνημα ἐν ἀνθρώποις παρασχόμενος συνεχῶς ἐπταικόσι καὶ διʼ αὐτὸ οὐδὲ ἓν χρηστὸν οὐδὲ ἐς τὰ μέλλοντα ἐλπίζουσι.
Near the southern wall, Attalus dedicated statues, each approximately two cubits in height, showing the legendary war against the Giants, who once inhabited Thrace and the isthmus of Pallene, as well as the battle of the Athenians against the Amazons, their deed at Marathon against the Persians, and the rout of the Gauls in Mysia. There also stands a statue of Olympiodorus, highly esteemed for the brilliance of his achievements and especially for his timing, since he inspired continual courage among men at a critical moment, when they had completely given way and had no hope remaining for the future.
