 He died at Naples in 1822.In the 17–21 January 1809 edition of the "Zeitung für die elegante Welt" he published an article severely criticising Caspar David Friedrich's painting "Cross in the Mountains (Tetschen Altar)" (1808) and the school of German Romanticism to which it belonged.He was disturbed by the unacademic style of the painting, having little in common with the traditions established by Claude Lorraine and Jacob van Ruisdael, and deeply indignant that Friedrich should have presented it as an altarpiece to a private chapel.
