Sometimes, authors explain after whom or what a place or people was named and thus illustrate derivation to form an adjective, with various suffixes, from an noun. More examples to follow... ?

Herodotus, I 7.3
Οἱ δὲ πρότερον Ἄγρωνος βασιλεύσαντες ταύτης τῆς χώρης ἦσαν ἀπόγονοι Λυδοῦ τοῦ Ἄτυος, ἀπ’ ὅτεο ὁ δῆμος Λύδιος ἐκλήθη ὁ πᾶς οὗτος, πρότερον Μηίων καλεόμενος.
 
Mark the Deacon, Life of Porphyrius, 64:
Ἦσαν δὲ ἐν τῇ πόλει ναοὶ εἰδώλων δημόσιοι ὀκτώ, τοῦ τε Ἡλίου καὶ τῆς Ἀφροδίτης καὶ τοῦ Ἀπόλλωνος καὶ τῆς Κόρης καὶ τῆς Ἑκάτης καὶ τὸ λεγόμενον Ἡρωεῖον καὶ τῆς Τύχης τῆς πόλεως, ὃ ἐκάλουν Τυχαῖον, καὶ τὸ Μαρνεῖον, ὃ ἔλεγον εἶναι τοῦ Κρηταγενοῦς Διός, ὃ ἐνόμιζον εἶναι ἐνδοξότερον πάντων τῶν ἱερῶν τῶν ἁπανταχοῦ.

ibid., 91:
Ὁ δὲ μακάριος ἐποίησεν πάντας ἀναθεματίσαι τὸν Μάνην τὸν ἀρχηγὸν τῆς αὐτῶν αἱρέσεως, ἐξ οὗ καὶ Μανιχαῖοι ἐκλήθησαν, καὶ κατηχήσας αὐτοὺς δεόντως ἐπὶ πλείστας ἡμέρας προσήγαγεν τῇ ἁγίᾳ καθολικῇ ἐκκλησίᾳ.

ibid., 92:
Μετὰ δὲ πενταετῆ χρόνον ἐτελειώθη τὸ ἔργον τῆς ἁγίας ἐκκλησίας τῆς μεγάλης, ἐκλήθη δὲ Εὐδοξιανὴ ἐκ τοῦ ὀνόματος τῆς θεοφιλεστάτης Εὐδοξίας τῆς βασιλίδος.
