The length of the rule of the Hyksos is as unknown to us as the number of their kings. Manetho makes two dynasties (Dynasties XV and XVI) rule, which, according to Josephus, reigned 511 years altogether over the whole of Egypt, whilst the tables of Africanus give 284 to the XVth (an evident misquotation of Josephus 260) and 518 to the XVIth. For the XVIIth Dynasty, according to Africanus, 43 Shepherds and 43 Theban kings ruled for 151 years; and this is the era of the struggle for freedom, which ended with the expulsion of the Hyksos. It is impossible for these figures to be correct, but there is no means of getting at the historical truth, even approximately. It can be said, however, that according to the monuments there is no gap of five hundred or more years between the end of the XIIIth Dynasty and the beginning of the New Kingdom. The pedigrees of the nomarchs and nobles of El-Kab (Eileithyia) give names after a few generations, which are undoubtedly contemporaneous with the XIIIth and XIVth Dynasties. The monuments of the first rulers of the New Kingdom in Thebes show the closest connection with the more ancient Theban, and strikingly so with those of the XIth Dynasty. There is, certainly between the time of Amenemhat and Sebekhotep and the New Kingdom, no distinctive break in culture and art similar to that between the Old Kingdom of Memphis and the XIIth Dynasty. Manetho’s figures have evidently to be very considerably reduced. Some of the short-lived rulers of the Egyptian dynasties must be regarded as contemporaneous with the Hyksos kings and connected directly with the first rulers of the New Kingdom who undertook the struggle for emancipation. If we allow 150 years for the first kings of the XIII Dynasty,--and dates are inevitable,--about four hundred years would be reckoned from the end of the XIIth Dynasty to the expulsion of the Hyksos under Aahmes. Moreover, we also know that a Hyksos king, Nub, reigned four hundred years before Ramses II.[g] It will be clear to the reader, from the account just given, that the period of the XIIIth-XVIIth Dynasties is one of which we have very little knowledge. Not only is the Turin papyrus here much broken, but the intrusion of the Hyksos has greatly confused the knowledge we have indirectly from Manetho through Josephus, Africanus, Eusebius, and others. Petrie has made a careful study of the subject, and his conclusions are, in brief, as follows: 1. The Hyksos were not contemporaneous with the 453 years of the XIIIth Dynasty. 2. There is a period of about 100 years during the XIVth Egyptian Dynasty during which the Hyksos gradually came into power, and
