Beethoven took the manuscripts of the Appassionata Sonata (here played by Daniel Barenboem) and string quartets Opus 59 (here is Number 1 played by the Juilliard Quartet, and 2 played by the Castalian Quartet) to stay with his princely patron. Then they had a huge row and Beethoven rushed back to Vienna in a storm. You can see the water-stains on the manuscripts.
