"[8] Next comes the Latmian Gulf, on which is situated "Heracleia below Latmus," as it is called, a small town that has an anchoring-place. It was at first called Latmus, the same name as the mountain that lies above it, which Hecataeus indicates, in his opinion, to be the same as that which by the poet is called "the mountain of the Phtheires" (for he says that the mountain of the Phtheires lies above Latmus), though some say that it is Mt. Grium, which is approximately parallel to Latmus and extends inland from Milesia towards the east through Caria to Euromus and Chalcetores. This mountain lies above Heracleia, and at a high elevation. At a slight distance away from it, after one has crossed a little river near Latmus, there is to be seen the sepulchre of Endymion, in a cave. Then from Heracleia to Pyrrha, a small town, there is a voyage of about one hundred stadia.
[9] But the voyage from Miletus to Heracleia, including the sinuosities of the gulfs, is a little more than one hundred stadia, though that from Miletus to Pyrrha, in a straight course, is only thirty--so much longer is the journey along the coast. But in the case of famous places my reader must need to endure the dry escriptions of geography.
