accumulated a considerable amount of knowledge about the Scythians, the Aryan people who were then distributed over South Russia; he went to the south of Italy, explored the antiquities of Tyre, coasted Palestine, landed at Gaza, and made a long stay in Egypt. He went about Egypt looking at temples and monuments and gathering information. We know, not only from him, but from other evidence, that in those days the older temples and the pyramids (which were already nearly three thousand years old) were visited by strings of tourists, a special sort of priests acting as guides. The inscriptions the sightseers scribbled upon the walls remain to this day, and many of them have been deciphered and published.
