In 1766 the Marquis de Mirabeau, the father of the celebrated revolutionary orator, declared that history was over. “There have been, since the world began,” he wrote, “three great inventions which have principally given stability to political societies.

The table in question, a bizarre arrangement of squiggles and zig-zags, has come down to us. A copy was discovered in the marquis’s papers in the French national archives in Paris at the end of the 19th century and published soon afterward to a mystification as deep as it was complete. Devised by Mirabeau’s friend, Fran?ois de Quesnay, a part-time economist and full-time gynaecologist to Mme de Pompadour, it purported to show the way in which money multiplies in society.

A century later, the economists are still at it. In his Principles of Economics, Alfred Marshall, Keynes’s master and the founder of the modern British school of economics, announced that he had uncovered the sec…
