Passage 8.42.9
Ὀνάτα καὶ ταῦτα ποιήματα, καὶ ἐπιγράμματα ἐν Ὀλυμπίᾳ, τὸ μὲν ὑπὲρ τοῦ ἀναθήματός ἐστιν αὐτῶν, σόν ποτε νικήσας, Ζεῦ Ὀλύμπιε, σεμνὸν ἀγῶνα τεθρίππῳ μὲν ἅπαξ, μουνοκέλητι δὲ δίς, δῶρα Ἱέρων τάδε σοι ἐχαρίσσατο· παῖς δʼ ἀνέθηκε Δεινομένης πατρὸς μνῆμα Συρακοσίου·
These also are works of Onatas, and inscriptions in Olympia; one of them, upon a dedication, runs thus: "O Olympian Zeus, having once won your revered contest with his four-horse chariot, and twice with a single steed, Hieron presented to you these gifts; his son dedicated them as memorials of his father Deinomenes of Syracuse."
