an Ionian town, situated in Caria, on the S. bank of the River Maeander, about 30 stadia from its mouth. It was founded, according to Strabo, by Cydrelus, a natural son of Codrus; and in the days of that geographer its population, already very much lessened, had become incorporated with that of Miletus, and ceased to exist as a distinct political corporation. This desertion of their native town, on the part of the Myusians, is ascribed by Pausanias to the extraordinary number of flies which infested it, and which rendered the life of the inhabitants intolerable. Some think, however, that their removal was more probably owing to the numerous inundations to which, according to Vitruvius, their town was exposed. The King of Persia bestowed Myus, among other towns, upon Themistocles; and Philip of Macedon, after having made it his own, gave it to the Magnesians. We learn from Pausanias that this town possessed a beautiful temple, built of white marble, dedicated to Dionysus. Few traces of Myus now remain; and from the amount of debris annually carried down by the waters of the Maeander, and deposited at its mouth, the original distance of this ancient town from the sea has become very much increased; so that modern travellers have not unfrequently mistaken its site for that of Miletus, and erroneously identified Heracleia with Myus.
