The athlete in Pausanias and Eusebius is clearly the same man. Brunet interprets the victories enlisted in I.Strat. 1042 (= CIG 2723) as belonging to Aristeas, rather than to his son, as were Moretti's conclusions (1957, no. 780) after consulting 'the less than perfect version given in CIG'. I follow Brunet (and consequently Gouw) here in attributing the victories to Aristeas himself.
The inscription from Stratonikeia is very fragmentary.
I. Strat: Aristeas won the periodos in pale and pankration for men as the first of the people from Asia. He also was the first of the oikoumene to win the periodos in the periodos (i.e. in four years) (ll. 9-13: - [— Ὀλύμπια] Πύθια Νέμεα / [Ἴσθμια πρώτου τῶν ἀπὸ] / τῆς Ἀσίας ἀν/[δρῶν πάλην πα]νκράτιον, <π>ρώτο[υ] / [τῶν ἀπὸ τῆς οἰκου]μένης στεφανω̣/[θέντος
τὴν περίοδ]ον ἐν περιόδῳ).
