Passage 6.17.9
ἀλλά γε ἐκείνου τε ἐς πλέον τιμῆς ἀφίκετο ὁ Γοργίας παρὰ Ἀθηναίοις, καὶ Ἰάσων ἐν Θεσσαλίᾳ τυραννήσας Πολυκράτους, οὐ τὰ ἔσχατα ἐνεγκαμένου διδασκαλείου τοῦ Ἀθήνῃσι, τούτου τοῦ ἀνδρὸς ἐπίπροσθεν αὐτὸν ὁ Ἰάσων ἐποιήσατο. βιῶναι δὲ ἔτη Γοργίαν πέντε φασὶν ἐπὶ τοῖς ἑκατόν· Λεοντίνων δὲ ἐρημωθεῖσάν ποτε ὑπὸ Συρακουσίων τὴν πόλιν κατʼ ἐμὲ αὖθις συνέβαινεν οἰκεῖσθαι.
But certainly Gorgias won even greater honor among the Athenians than he who taught him, and Jason, who ruled as tyrant in Thessaly, placed him ahead of Polycrates, whose rhetorical school in Athens was far from insignificant. They say Gorgias lived to be one hundred and five years old. As for Leontini, once depopulated by the Syracusans, in my own day it happened to be inhabited again.
