These, I am of opinion, were the furthest people to which the Egyptian army came, for in their country the pillars are found to have been set up, but in the land beyond this they are no longer found.

– Herodotus, Book II
Herodotus made his living by being interesting. In a world where most people did not read and could not afford to buy a book even if they could, they would pay to listen to Herodotus recite from his books. They would not pay to be bored.
