 There were some efforts at model building in the eighteenth century. Jean-François Melon (1734), whose work was widely known, constructed a model based on three similar islands with two goods in circulation (see Hont 2005: 30–32). Quesnay’s tableau économique (1758) was the most celebrated model. His disciple, Pierre Samuel Du Pont de Nemours, published a treatise in 1768 that promoted physiocracy as a “new science” on equal standing with the natural sciences. Adam Smith intended to dedicate the Wealth of Nations to Quesnay, but he died too soon.
