Passage 6.16.4
Ἀριστείδῃ δὲ Ἠλείῳ γενέσθαι μὲν ὅπλου νίκην ἐν Ὀλυμπίᾳ, γενέσθαι δὲ καὶ διαύλου Πυθοῖ τὸ ἐπίγραμμα τὸ ἐπʼ αὐτῷ δηλοῖ Νεμείων τε ἐν παισὶν ἐπὶ τῷ ἱππίῳ δρόμῳ . δρόμου δέ εἰσι τοῦ ἱππίου μῆκος μὲν δίαυλοι δύο, ἐκλειφθέντα δὲ ἐκ Νεμείων τε καὶ Ἰσθμίων αὐτὸν βασιλεὺς Ἀδριανὸς ἐς Νεμείων ἀγῶνα τῶν χειμερινῶν ἀπέδωκεν Ἀργείοις.
An inscription concerning Aristeides of Elis records that he gained a victory in the hoplitodromos at Olympia, and also in the diaulos at Pytho, as well as among the youths in the hippios race at Nemea. The hippios race is two diauloi in length. After it had been discontinued at Nemea and at Isthmia, the emperor Hadrian restored it to the Argives for inclusion in their winter Nemean games.
