Passage 6.16.2
Τυδεὺς δὲ Ἠλεῖος Ἀντίγονόν τε τὸν Δημητρίου πατέρα καὶ Σέλευκον ἀνέθηκε· Σελεύκου δὲ ἐς ἅπαντας ἤρθη τὸ ὄνομα ἀνθρώπους ἄλλων τε ἕνεκα καὶ διὰ τὴν Δημητρίου μάλιστα ἅλωσιν. Τίμωνι δὲ ἀγώνων τε νῖκαι τῶν ἐν Ἕλλησιν ὑπάρχουσιν ἐπὶ πεντάθλῳ πλὴν τοῦ Ἰσθμικοῦ---τούτου δὲ τῷ μὴ ἀγωνιστὴς γενέσθαι κατὰ τὰ αὐτὰ Ἠλείοις τοῖς ἄλλοις εἴργετο ---καὶ τάδε ἄλλα φησὶ τὸ ἐς αὐτὸν ἐπίγραμμα, Αἰτωλοῖς αὐτὸν ἐπιστρατείας μετασχεῖν ἐπὶ Θεσσαλοὺς καὶ φρουρᾶς ἡγεμόνα ἐν Ναυπάκτῳ φιλίᾳ γενέσθαι τῇ ἐς Αἰτωλούς.
Tydeus, an Elean, made offerings dedicated to Antigonus, the father of Demetrius, and to Seleucus. The fame of Seleucus became widespread among all mankind for many reasons, and especially because of his capture of Demetrius. Concerning Timon, victories were his in the pentathlon at all the Greek games except the Isthmian; from this competition he was excluded, in accordance with the general practice against Eleans, because he did not actually enter the contest. Further, the inscription regarding him recounts these additional details: Timon joined the Aetolians in their expedition against the Thessalians and became commander of their garrison at Naupactus, owing to the friendship he had formed with the Aetolians.
