A second path, which has lately been struck out for the reduction of Manetho's dynasties, is based upon the list of Eratosthenes. The thirty-eight kings enumerated in this list are placed beside the first fourteen dynasties of Manetho. It is assumed that only the names quoted in Eratosthenes are the names of real monarchs, and that we must look for similar names in the list of Manetho. By this assumption, it is true, we are compelled to set aside several of Manetho's dynasties, and even to throw away the greater part of the kings of the dynasties which are allowed to count in the series.[27] But even when we have overcome all the difficulties in the way of this system, we are still without the means to define accurately the duration of the rule of the alien kings, which, as has been already remarked, according to the various excerpts from the list of Manetho, continued 953, or 511, or 103 years; nor is there any fixed point immediately before the alien monarchy to enable us to succeed in establishing the antiquity and commencement of the Egyptian series of kings. All attempts to arrive at the antiquity of the civilisation and history of Egypt by these means are the more doubtful, because in Egypt there is no fixed era to form a basis for calculation. The time is reckoned by the reigns of the kings. In such a case even the most cautious inquiry of the priests could hardly have arrived at a satisfactory chronology for the oldest period. Though they had before them far more numerous monuments than we have, and though the lists of the various dominant families began to be kept at a very early period, it was no longer possible at the time when the lists of the Turin papyrus were made out, to discover in what order the families came, or which ruled contemporaneously before the time of the alien kings. The mere arrangement of our materials in the order of succession cannot fail to give an entirely false picture of the history of Egypt, while on the other hand the national pride of the Egyptians, and the vanity of the priests, found a great satisfaction in exaggerating the antiquity of their history by such enumerations, even where it was known that any families of kings were contemporaneous. With what pride and complacency would they exhibit this endless list of kings to the travelling strangers from Greece!
