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.”

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.”

In an 1846 math textbook from the Free Grammar School of King Edward VI, one exercise considers an exchange of 450 bags of potatoes for cash, 15 chests of oranges, and 185 bushels of carrots; the remainder is nuts. The question is posed: “How many bags of nuts did I receive?”
