Passage 5.25.10
γέγραπται δὲ καὶ ἐπίγραμμα ἐπὶ τῷ βάθρῳ· τῷ Διὶ τἈχαιοὶ τἀγάλματα ταῦτʼ ἀνέθηκαν, ἔγγονοι ἀντιθέου Τανταλίδα Πέλοπος. τοῦτο μὲν δὴ ἐνταῦθά ἐστι γεγραμμένον· ὁ δὲ ἀγαλματοποιὸς ὅστις ἦν, ἐπὶ τοῦ Ἰδομενέως γέγραπται τῇ ἀσπίδι· πολλὰ μὲν ἄλλα σοφοῦ ποιήματα καὶ τόδʼ Ὀνάτα ἔργον Αἰγινήτεω, τὸν γείνατο παῖδα Μίκων.
An epigram is also written upon the pedestal: "These statues the Achaeans dedicated to Zeus, Descendants of divine Pelops, son of Tantalus." That inscription is indeed found here. The name of the sculptor, whoever he was, is engraved upon the shield of Idomeneus: "Many other skilful works as well as this one are by Onatas, The Aeginetan, whom Mikon begot as his son."
