Oh My God, that's painful!
German troops, when they marched in at the end of the Second Empire, used pictures painted by Monet and Pissarro as floor mats and aprons in a regimental butcher shop! Tragedy seems a rather paltry word.
In case you're wondering, Monet was "able to recover many of his paintings" although "almost all of Pissarro's prewar output was irreparably damaged or destroyed."
As for the seemingly lack of movement, I swear I'm reading...but note taking is slowing me down. I'm learning so much!
