Passage 5.8.1
τούτων δὲ ὕστερον Κλύμενον τὸν Κάρδυος, πεντηκοστῷ μάλιστα ἔτει μετὰ τὴν συμβᾶσαν ἐπὶ Δευκαλίωνος ἐν Ἕλλησιν ἐπομβρίαν ἐλθόντα ἐκ Κρήτης, γένος ἀπὸ Ἡρακλέους ὄντα τοῦ Ἰδαίου, τόν τε ἀγῶνα ἐν Ὀλυμπίᾳ θεῖναι καὶ Κούρησι τοῖς τε ἄλλοις καὶ Ἡρακλεῖ τῷ προγόνῳ λέγουσιν ἱδρύσασθαι βωμόν, Παραστάτην ἐπωνυμίαν τῷ Ἡρακλεῖ θέμενον. Ἐνδυμίων δὲ ὁ Ἀεθλίου Κλύμενόν τε ἔπαυσε τῆς ἀρχῆς καὶ δρόμου τοῖς υἱοῖς ἆθλα ἐν Ὀλυμπίᾳ τὴν βασιλείαν ἔθηκε.
After these events, about fifty years after the great flood that befell the Greeks during Deucalion's time, it is said that Clymenus, son of Cardys, came from Crete—he who traced his lineage back to Heracles of Ida. They say he established the contest at Olympia, and built an altar there for the Curetes and for Heracles, his own ancestor, giving Heracles the surname "Parastates" (the Helper). Endymion, son of Aethlius, however, deposed Clymenus from power and established royal authority at Olympia as the prize in a footrace among his own sons.
