The art of this period is throughout archaic, constituting a period of efflorescence distinguished by excellence and neatness of the forms, but wanting in all originality. In writing, the endeavour is made as far as possible to imitate the old models. Naturally in this manner the relative simplicity and naturalness of the olden times was not reached; the heritage of a thousand years’ development, the endless magic and formal ritual with its wearying system and its dead phrases, is carefully preserved and ever increased. If, according to Greek reports, the Egyptians believed in the transmigration of souls after death into the body of another being, and that, after having gone through all the animals of land and sea and air, they returned to human form after three thousand years, this doctrine, which is nowhere to be found in manuscripts left to us, may have arisen at this time from their view of conditions after death and the consubstantiality of all life. That Egypt which the Greeks learnt to know was a well-preserved mummy of primitive times and served to impress them by its uniqueness and its age, and individually to stimulate, but was no more in a position to awaken a new life. In the social domain, if we can believe the reports of the Greeks, the separation of classes was brought about. The priesthood was an exclusive caste, and their dignity was hereditary; next to them come the completely exclusive warrior class, consisting of the successors of the Ma, divided into the Calasirians and Hermotybians. Priests as well as warriors are exempt from taxes and in possession of a great part of the agricultural land, which they hire out to peasants for large sums of money. The remaining part of the soil is royal dominion. Far below the privileged classes stands the mass of the people, the labourers, manufacturers, merchants, finally the shepherds of the Delta, of Semitic descent, and the inhabitants of the Delta living on fisheries of the swamps, both of which are considered unclean in Egypt. In theory the principle may also be set down here that every class forms a decided caste; that this was not practically carried through is taught us by the report of Herodotus, II, 147, that the Shepherd race, being unclean, could marry only within itself. From which we may infer that other castes were permitted to intermarry.[d] THE PERSIAN CONQUEST AND THE END OF EGYPTIAN AUTONOMY [Sidenote: [596-572 B.C.]] With the XXVIth Dynasty the curtain was practically drawn for all time on Egyptian autonomy. The recurrent struggle between Asia and Africa was renewed with disastrous consequences to the people of the Nile. We have here to do with the Persian conquest, and in particular with the deeds of Cambyses.
