Passage 8.53.9
καλοῦσι δὲ οἱ Τεγεᾶται καὶ ἑστίαν Ἀρκάδων κοινήν· ἐνταῦθά ἐστιν ἄγαλμα Ἡρακλέους, πεποίηται δέ οἱ ἐπὶ τοῦ μηροῦ τραῦμα ἀπὸ τῆς μάχης ἣν πρώτην Ἱπποκόωντος τοῖς παισὶν ἐμαχέσατο. τὸ δὲ χωρίον τὸ ὑψηλόν, ἐφʼ οὗ καὶ οἱ βωμοὶ Τεγεάταις εἰσὶν οἱ πολλοί, καλεῖται μὲν Διὸς Κλαρίου, δῆλα δὲ ὡς ἐγένετο ἡ ἐπίκλησις τῷ θεῷ τοῦ κλήρου τῶν παίδων ἕνεκα τῶν Ἀρκάδος.
The Tegeans also call this place the Common Hearth of the Arcadians. Here there is a statue of Heracles, and on his thigh a wound is represented, which he received in that first battle fought against the sons of Hippocoon. The elevated ground, on which most of the altars of the Tegeans stand, is named Zeus Klarios; clearly this epithet was given to the god because of the casting of lots among the sons of Arcas.
