MO´TYUM(Μότυον), a small town or fortress of Sicily, in the territory of Agrigentum. It was besieged in B.C. 451 by the Siculian chief Ducetius, and fell into his hands after a battle in which he defeated the Agrigentines and their allies; but was recovered by the Agrigentines in the course of the following summer. (Diod. 11.91.) No other mention of it is found, and its site is wholly unknown.
