2. Megabyzus, the son of Zopyrus, and grandson of the above, was one of the commanders of the land forces in the expedition of Xerxes against Greece, B. C. 4 80. (Hdt. 7.82.) Megayzus was the commander of the army which Cimon defeated on the Eurymcdtlon, in uB. C. 466. (Diod. 12.3.) [CIMON.] When the Athenians made their expedition against Egypt, Megabyzus was sent against them with a large army; and having driven them out of Memphis, he shut them up in the island of Prosopitis, which he at last took, after a siege of eighteen months, B. C. 457. (lierod. 3.160; Thuc. 1.109; Diod. 11.74.6.) Ctesias informs us that he was the son-in-law of Xerxes, having married his daughter Amytis; and he ascribes to Megabyzus the service which Herodotus attributes to Zopyrus, namely, the taking of Babylon, after its revolt from Xerxes. (Pers. 22; Diod. 10.17.2; comp. Hdt. 3.153.) Several other incidents of his life are related by Ctesias. (Pers. 27, 30, 33-40.) Two sons of his are mentioned, Zopyrus and Artyphius. (Ctes 37; Hdt. 3.160.) He is always called Μεγάβυζος, except in a quotation from Ctesias by Stephanus (s. v. Κυρταῖα), who gives the name in the form Μεγάβαζος but even in this passage Westermann has printed it Μεγάβυζος
