A a Semitic people who were able to wrestle control of Egypt from the early Second Intermediate rulers of the 13th Dynasty, inaugurating the 15th Dynasty. Their names mostly come from the West Semitic languages, and earlier suggestions that some of these people were Hurrian or even Hittite. Until the Hyksos invasion, the history of Egypt and Asia were mostly isolated, while afterwards, they would be permanently entwined. Perhaps one of the greatest contribution of the Hyksos was the preservation of famous Egyptian documents, both literary and scientific. During the reign of Apophis, the fifth king of the “Great Hyksos,” scribes were commissioned to recopy Egyptian texts so they would not be lost. One such text was the Edwin Smith Surgical Papyrus. This unique text, dating from about 3000 BC, gives a clear perspective of the human body as studied by the Egyptians, with details of specific clinical cases, examinations, and prognosis. The Westcar Papyrus preserved the only known version of an ancient Egyptian story that may have otherwise been lost.
