...the Ethiopian Dynasty, however, is the only one that in the conventionally written history of Egypt, maintains its proper place. During the Nineteenth Dynasty the error of the accepted Egyptian chronology reached the high figure of over 700 years; and together with it the time of the contemporaneous rulers of the so-called Hittite Empire is equally misplaced by over 700 years.(1) Finally the Twentieth Dynasty -- that of Ramses III and his adversaries -- Peoples of the Sea -- needs to be brought closer to our time by a full 800 years and placed just a few decades before Alexander of Macedon. The Twenty-first Dynasty began under the Persian kings, continued contemporaneous with the Twentieth -- its rulers reigned in the Libyan Desert oases -- and lasted until the second Ptolemy.Collected Essays | History and Archaeology
