far from Memphis, and is better known to us by the name of On. It was the centre of the worship of Ra, as Abydos was of the worship of Osiris, but there was no jealousy or rivalry between the two. They were, in fact, essentially one, and the same individual might be priest or priestess of both sanctuaries.
On was famous from time immemorial as a seat of learning, and its priesthood was held in high repute. The city itself was of small dimensions. 'The walls may yet be traced,' says Mr. Reginald Stuart Poole, 'enclosing an irregular square of about half a mile in the measure of each of its sides.' And of this limited space the great temple of Ra must have occupied about half. The population, one would think, must have been mainly composed of scholars, as the priests' dwellings would be within the temple precincts. Hither came the young men of Egypt—who shall say how many thousand years ago!—to learn all that the priests could teach at this, the most ancient university of the world. Nor were the priests, who carefully cultivated and taught the various branches of learning, by any means an exclusive caste.
