A Byzantine general of “ignoble descent” oversaw the building of Petra, on the Colchian coast, and set up an import monopoly. “They are robbing us of all our gold as well as of the necessities of life, using the fair name of trade,” locals complained, according to Procopius. “There has been set over us as ruler a huckster who has made our destitution a kind of business.”

Herodotus reports that after Cyrus the Great was warned by a Spartan herald not to tread further into Greek lands, the Persian king received a primer on Sparta, including an explanation of an agora, to inform his response. “I have never yet been afraid of any men,” he told the herald, “who have a set place in the middle of their city where they come together to cheat each other.”

Before leaving his post as Qi chancellor in 193 bc, Cao Can gave advice to his successor: “If you stir up the markets and empty out the jails, then evil men will have no place to stay and will make trouble for you elsewhere.” A footnote in the English text from translator Burton Watson explains: “It was an assumption among Han officials and intellectuals that most, if not all, men engaged in trade were swindlers.”
