Passage 5.8.8
ὀγδόῃ δὲ ἀπὸ ταύτης Ὀλυμπιάδι ἐδέξαντο παγκρατιαστήν τε ἄνδρα καὶ ἵππον κέλητα· ἵππος μὲν δὴ Κραννωνίου Κραυξίδα παρέφθη, τοὺς δὲ ἐσελθόντας ἐπὶ τὸ παγκράτιον ὁ Λύγδαμις κατειργάσατο Συρακούσιος. τούτῳ πρὸς ταῖς λιθοτομίαις ἐστὶν ἐν Συρακούσαις μνῆμα· εἰ δὲ καὶ Ἡρακλεῖ τῷ Θηβαίῳ μέγεθος παρισοῦτο ὁ Λύγδαμις, ἐγὼ μὲν οὐκ οἶδα, λεγόμενον δὲ ὑπὸ Συρακουσίων ἐστί.
In the eighth Olympiad after this one, they admitted a man for the pankration and a horse for the riding race. The horse, in fact, was entered by Krauxidas from Krannon, and Lygdamis of Syracuse overcame those who competed in the pankration. There is a monument to this man beside the stone quarries at Syracuse; whether indeed Lygdamis equaled the stature of Heracles of Thebes, I cannot say, but this is what the Syracusans report.
