One of the most extensive surviving archives of Old Babylonian writing consists of letters sent to Ea-nasir, an eighteenth-century-bc copper merchant from Ur. “You have offered bad ingots to my messenger,” complained one trading partner. “Who am I that you are treating me in this manner?” Another customer appears repeatedly in the archive, each time inquiring about a missing copper shipment. “Do you not know,” he wrote in his third missive, “how tired I am?”

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.”

Corporations, wrote Edward Coke in a 1613 legal decision, “have no souls,” for they are “invisible, immortal, and resteth only in intendment and consideration of the law.” A corporate body, Coke argued, can’t “do fealty, for an invisible body cannot be in person, nor can swear.”

Including trademarks in books became crucial after the invention of the printing press; without stringent copyright laws, rival publishers could repurpose superiorly edited texts with impunity. Aldus Manutius of Venice, who employed Erasmus as a proofreader, called attention to his company’s “sign of the dolphin wound round the anchor.” Florentine printers were aping the mark, but in the frauds, “the head of the dolphin is turned to the left, whereas that of ours is well known to be turned to the right.”

A growing market for ejiao—a gelatin made from donkey hide believed by practitioners of traditional Chinese medicine to increase libido and slow aging—has led to a global trade of millions of donkey skins each year. Asses are often kidnapped from rural African villages, where their labor is valued highly, then taken to markets and slaughtered for export. “The donkeys,” said a sanctuary manager while visiting a market in Tanzania, “are very stressed.”
