Passage 7.5.12
Ἐρυθραίοις δὲ ἔστι μὲν χώρα Χαλκίς, ἀφʼ ἧς καὶ τῶν φυλῶν σφισιν ἡ τρίτη τὸ ὄνομα ἔσχηκεν, ἔστι δὲ τῆς Χαλκίδος κατατείνουσα ἐς τὸ πέλαγος ἄκρα καὶ ἐν αὐτῇ λουτρὰ θαλάσσια, μάλιστα τῶν ἐν Ἰωνίᾳ λουτρῶν ὠφέλιμα ἀνθρώποις. Σμυρναίοις δὲ ποταμὸς Μέλης ὕδωρ ἐστὶ κάλλιστον καὶ σπήλαιον ἐπὶ ταῖς πηγαῖς, ἔνθα Ὅμηρον ποιῆσαι τὰ ἔπη λέγουσι·
The Erythraeans have a region called Chalcis, from which their third tribe has also taken its name. Extending from Chalcis into the sea is a headland, upon which there are sea-baths, the most beneficial to mankind of all such baths in Ionia. As for the Smyrnaeans, they have the river Meles, whose water is exceedingly beautiful, and a cave near its springs, in which, they say, Homer composed his poems.
