2. A Saite, who, having been invested with the title of king of Egypt, was joined with Inarus the Libyan in the command of the Egyptians when they rebelled against Artaxerxes Longimanus (B. C. 460). After the first success of the Egyptians, B. C. 456 [ACHAEMENES], Artaxerxes sent a second immense army against them, by which they were totally defeated. Amyrtaeus escaped to the island of Elbo, and maintained himself as king in the marshy districts of Lower Egypt till about the year 414 B. C., when the Egyptians expelled the Persians, and Amyrtaeus reigned six years, being the only king of the 28th dynasty. His name on the monuments is thought to be Aomahorte. Eusebius calls him Amyrtes and Amyrtanus (Ἀμυρτάνος). (Hdt. 2.140, 3.15; Thuc. 1.110; Diod. 11.74, 75; Ctesias. apud Phot. pp. 27, 32, 40, Bekker; Euseb. Chron. Armen. pp. 106, 342, ed.
