The paper examines one segment of the biographies of Mentor and Memnon of Rhodes: the grants of holdings to them in Asia Minor. The author shows that there were two periods of the Rhodian brothers’ ownership of cities and lands there - the first, when they made a successful career under Artabazus, satrap of Hellespontine Phrygia, and the second, after Mentor managed to become one of the key persons in the military-political circle of Artaxerxes III Ochus. In the present article the special attention is paid to the problem of the location of these holdings in north-western Asia Minor in both of the named periods.
