Passage 8.48.6
πεποίηται δὲ καὶ Διὸς Τελείου βωμὸς καὶ ἄγαλμα τετράγωνον· περισσῶς γὰρ δή τι τῷ σχήματι τούτῳ φαίνονταί μοι χαίρειν οἱ Ἀρκάδες. καὶ μνήματά ἐστιν ἐνταῦθα Τεγεάτου τοῦ Λυκάονος καὶ Μαιρᾶς γυναικὸς τοῦ Τεγεάτου· θυγατέρα Ἄτλαντός φασιν εἶναι τὴν Μαιράν, ἧς δὴ καὶ Ὅμηρος ἐποιήσατο μνήμην ἐν Ὀδυσσέως λόγοις πρὸς Ἀλκίνουν περί τε ὁδοῦ τῆς ἐς Ἅιδην καὶ ὁπόσων ἐθεάσατο ἐκεῖ τὰς ψυχάς.
There is also an altar of Zeus Teleios, and his image is square-shaped; indeed, the Arcadians seem to me particularly fond of this particular form. Here also are the tombs of Tegeates, son of Lycaon, and of Maera, the wife of Tegeates. They say Maera was a daughter of Atlas, and Homer himself made mention of her in Odysseus' account to Alcinous concerning his journey to Hades and the souls he beheld there.
