Amidst the flurry of Waterloo commemorations it is worth remembering that the defeat of Napoleon represented a major cultural watershed; for 18 years Britain had been at war with France and the sense of relief at a tyrant having been vanquished must have been enormous. Some years ago we sold this brilliant drawing by Thomas Rowlandson of Little Nap Horner or Bonaparte meeting his Old friend on his arrival at St Helena. Rowlandson shows the fallen emperor, incarcerated on a small island in the South Atlantic, greeted by the devil who hands him a pick and a shovel. Rowlandson revels in the idea of the once great man tortured by his failure and contemplating his own mortality.
