Passage 7.5.10
ἡ δὲ Ἰωνία παρὲξ τῶν τε ἱερῶν καὶ τῆς τοῦ ἀέρος κράσεως παρέχεται καὶ ἄλλα ἐς συγγραφήν, ἡ μέν γε Ἐφεσία χώρα τόν τε Κέγχριον ποταμὸν καὶ τοῦ Πίονος τοῦ ὄρους τὴν φύσιν καὶ πηγὴν τὴν Ἁλιταίαν· ἐν δὲ τῇ Μιλησίᾳ πηγή τέ ἐστι Βιβλὶς καὶ ὅσα ἐς τῆς Βιβλίδος τὸν ἔρωτα ᾄδουσιν· ἐν δὲ τῇ Κολοφωνίων ἄλσος τε τοῦ Ἀπόλλωνος, δένδρα μελίαι, καὶ οὐ πόρρω τοῦ ἄλσους Ἄλης ποταμὸς ψυχρότατος τῶν ἐν Ἰωνίᾳ.
Ionia, beyond its temples and the temperate quality of its air, provides other subjects worthy of description. The Ephesian territory, for instance, includes the river Cenchrius, the nature of Mount Pion, and the Halitaea spring. In the Milesian land there is the spring called Byblis, together with all that poets recount concerning the love of Byblis. Near Colophon stands the grove of Apollo with ash trees, and not far from the grove flows the river Ales, the coldest of all rivers in Ionia.
