Passage 1.29.3
ἱερὰ μέν σφισι ταύτῃ τοσαῦτά ἐστι, τάφοι δὲ Θρασυβούλου μὲν πρῶτον τοῦ Λύκου, ἀνδρὸς τῶν τε ὕστερον καὶ ὅσοι πρὸ αὐτοῦ γεγόνασιν Ἀθηναίοις λόγιμοι τὰ πάντα ἀρίστου---παρέντι δέ μοι τὰ πλείω τοσάδε ἐς πίστιν ἀρκέσει τοῦ λόγου· τυραννίδα γὰρ ἔπαυσε τῶν τριάκοντα καλουμένων σὺν ἀνδράσιν ἑξήκοντα τὸ κατʼ ἀρχὰς ὁρμηθεὶς ἐκ Θηβῶν, καὶ Ἀθηναίους στασιάζοντας διαλλαγῆναι καὶ συνθεμένους ἔπεισε μεῖναι---, πρῶτος μέν ἐστιν οὗτος τάφος, ἐπὶ δὲ αὐτῷ Περικλέους τε καὶ Χαβρίου καὶ Φορμίωνος.
Such are the sanctuaries hereabouts; and among tombs, first is that of Thrasybulus, son of Lycus, a man who surpassed in every excellence all Athenians noteworthy both before and after him—my following brief statement will sufficiently confirm this assertion: for it was he who, first setting out from Thebes with only sixty men, overthrew the tyranny of those called the Thirty, and persuaded the Athenians, who were then afflicted with civil strife, to reconcile and abide by the agreements made. This tomb stands first; after it come those of Pericles, Chabrias, and Phormio.
