Passage 8.4.3
ἐγεγόνει δὲ αὐτῷ πρότερον ἔτι Αὐτόλαος νόθος. τοῖς δὲ παισίν, ὡς ηὐξήθησαν, διένειμεν Ἀρκὰς τριχῇ τὴν χώραν, καὶ ἀπὸ μὲν Ἀζᾶνος ἡ Ἀζανία μοῖρα ὠνομάσθη· παρὰ τούτων δὲ ἀποικισθῆναι λέγουσιν, ὅσοι περὶ τὸ ἄντρον ἐν Φρυγίᾳ τὸ καλούμενον Στεῦνος καὶ Πέγκαλαν ποταμὸν οἰκοῦσιν. Ἀφείδας δὲ Τεγέαν καὶ τὴν προσεχῆ ταύτης ἔλαχεν· ἐπὶ τούτῳ δὲ καὶ ποιηταὶ καλοῦσιν Ἀφειδάντειον κλῆρον τὴν Τεγέαν.
Autolaus, an illegitimate son, had been born to him earlier still. When the genuine sons came of age, Arcas divided the land among them into three parts. The portion given to Azan was called Azania after him. They say it was from these people that colonists went forth to settle the region in Phrygia around the cave called Steunos and the river Pencalas. Apheidas obtained Tegea and the territory adjoining it; and because of him, the poets call the land of Tegea the "Apheidantian allotment."
