Passage 6.12.2
παρὰ δὲ τοῦ Ἱέρωνος τὸ ἅρμα ἀνήρ ἐστιν ὁμώνυμός τε τῷ Δεινομένους καὶ ἐν Συρακούσαις καὶ οὗτος τυραννήσας, Ἱέρων δὲ ἐκαλεῖτο Ἱεροκλέους· μετὰ δὲ τὴν Ἀγαθοκλέους τοῦ πρότερον τυραννήσαντος τελευτὴν Συρακουσίοις αὖθις ἀναπεφύκει τύραννος ὁ Ἱέρων οὗτος, τὴν δὲ ἀρχὴν εἶχεν ἔτει δευτέρῳ τῆς ἕκτης Ὀλυμπιάδος ἐπὶ ταῖς εἴκοσι καὶ ἑκατόν, ἣν Κυρηναῖος στάδιον ἐνίκησεν Ἰδαῖος.
Next to Hiero's chariot stands a man who shares both the name and role of tyrant in Syracuse with the son of Deinomenes. This Hiero was the son of Hierocles, and after the death of Agathocles, who previously had reigned as tyrant, he rose again as ruler over the Syracusans. His reign began in the second year of the hundred-and-twenty-sixth Olympiad, in which Idaeus of Cyrene gained victory in the stadion race.
