ARSU.  Or Areos.  The name of a great Syrian chief who invaded the Delta of Egypt during the disputes between the successors of Merenpthah I.  He overthrew the established religion of the country, degraded the deities to the condition of mere men, connected the commerce of Egypt, and loosening the bands of allegiance set all the nation in revolt.  After some years of anarchy, he was dethroned by the tact and bravery of Prince Seti-Nekht, who aided by the native clergy expelled the Syrians, reversed their alterations, and restored the kingdom to order and prosperity. (An Archaic Dictionary, Cooper, 1876).
