 Piranesi collaborated with the French artist Louis Jean Desprez on a series of views of Naples, Pompeii and Rome, which were advertised in 1783 as "dessins coloriés" and sold at Piranesi's shop in Rome.Although the 1783 advertisement promised 48 views, the series was not completed before Desprez left Rome to enter the employ of King Gustav III of Sweden.In the following years, Piranesi built his reputation primarily upon his engravings of antique statuary.
