Discusses various place-names (Babylon, Kastalōn, Hermon/Almon/Salmon), foundation of Babylon attributed to Belus and older than Semiramis, references to Herodotus, Artemidorus, Callimachus, and an accentuation/phonological rule for words ending in -μων in toponyms.
Συρίαν στρατεῦσαι κἀκεῖ παρθένου ἐρασθέντα πόλιν κτίσαι, ἣν ἀφ´ ἑαυτοῦ οὕτως ὠνόμασε. τὰ αὐτὰ καὶ Νικόλαος ἐν τετάρτῃ ἱστοριῶν. Καστάλων μεγίστη πόλις Ὠρητανίας, ὡς Ἀρτεμίδωρος τρίτῳ γεωγραφουμένων. Ἀπόλλων, Κεφάλων, Ἀτιτάλλων. τὸ δὲ ἀμπελών καὶ καμηλών ὡς περιεκτικὰ ὀξύνεται· τὸ Βαβυλών ἀρσενικῶς, ἀφ´ οὗ καὶ ἡ πόλις. ἔστι γὰρ κτίσμα Βαβυλῶνος παιδὸς Βήλου παλαίτατον, οὐχ ὡς Ἡρόδοτος ὑπὸ Σεμιράμιδος· ταύτης γὰρ ἦν ἀρχαιοτέρα ἔτεσι χιλίοις δύο, ὡς Ἑρέννιος. ἔστι καὶ ἐν Αἰγύπτῳ πόλις. ὁμοίως καὶ τὸ μιμαλλών θηλυκόν, ἤτοι μαινάς. οὕτω Καλλίμαχος. Τὰ εἰς 'μων' μὴ ὄντα τοπικὰ ἢ ὁπότε μὴ ἐπὶ καιροῦ λαμβάνοιτο ἢ ἔχοι πρὸ τέλους τὸ 'υ' ἐκτεταμένον, βαρύνεται, Ἕρμων, Ἄλμων ἢ Σάλμων, πόλις Βοιωτίας, ἣν Ἑλλάνικος Ἄλμον φησὶ καὶ Σάλμον ἐν δευτέρῳ Δευκαλιωνείας, Τίμων, Σίμων, Ἄμμων, ἀφ´ οὗ πᾶσα ἡ
He campaigned in Syria and there, having fallen in love with a maiden, founded a city, which he thus named after himself. The same things also Nicolaus (says) in the fourth book of his Histories. Castalon, a very great city of Oretania, as Artemidorus (says) in the third book of his Geographical Works. Ἀπόλλων, Κεφάλων, Ἀτιτάλλων. But ἀμπελών and καμηλών, as collective nouns, are accented with an acute; and Βαβυλών is masculine, from which (comes) also the city. For it is a very ancient foundation of Babylon, son of Belus, not, as Herodotus (says), by Semiramis; for she was earlier than this woman by two thousand years, as Herennius (says). There is also a city in Egypt. Likewise μιμαλλών is feminine, that is, a maenad. So Callimachus. Words in -μων that are not place-names, or whenever they are not taken in a temporal sense, or have before the end an extended υ, are accented with a grave: Ἕρμων, Ἄλμων or Σάλμων, a city of Boeotia, which Hellanicus says is Ἄλμον and Σάλμον in the second book of the Deucalioneia; Τίμων, Σίμων, Ἄμμων, from whom the whole…
