Slightly later, as said before, Richard Cantillon, an expert in the economies of France and Britain, wrote his Essai sur la Nature du commerce en général.
The work was not published until 1755, but it circulated freely beforehand and quickly became famous. It was the first compendium of the science that was to be known as political economy, and offered a vision of the economy as a world that could be described by means of theoretical laws. Boisguilbert, Vauban and Cantillon planted the seeds of the physiocrats theories.
