The panorama is the work of several hands, but its similarity to Robert Havell Junior's 1831 Aeronautical View of London suggests he may have been involved in its production.
The piece was bought last year at Sotheby's for pounds 199,500, with money from the Heritage Lottery Fund, the National Art Collections Fund and the Victoria and Albert Museum. After 18 months of restoration, it has just gone on show at the Museum of London.
"It's a social document of a particular historical moment," explains Dr Lucy Peltz, assistant curator of paintings at the museum. "It depicts both the fashionable and commercial life of London, at a time when the country was isolated, but growing in economic strength." It was isolated, of course, because of the political disagreements between France and England that would be settled at the battle of Waterloo in 1812. If only Napoleon had seen this painting: to have London at his feet in panorama form might have been some consolation for his defeat.
A city laid bare
Some elements of the panorama are stylised: the perspective has been forced, to fit the city into the frame, and the blueness of certain church spires serves to direct the eye towards buildings of the greatest historical interest. On the left, notice the factory fire raging in Bermondsey, the funeral taking place at St John's churchyard in Southwark, the distant shape of the pagoda at Kew Gardens. Towards the right, there is a man firing a cannon on Brass Mount Battery at the Tower of London, sailors begging with a model boat and a man flying a kite over Tower Hill.
