Can you show me a list of priceless works of art that are destroyed or stolen?

I did a google search for destroyed works of art. Of particular interest is the campaign by the Nazis to destroy “degenerate” abstract art. I did a separate google search for works of art destroyed by fire.

Upon the death of William Blake his widow, Catherine, inherited his entire estate. They had no children and on her death she left the whole lot to Frederick Tatham (or so he claimed, whatever the case he ended up with them), a friend and devotee of Blake who took in and cared for Cathrine after Blake’s death. Years later in a fit of new-found religious fervor Tatham destroyed a number of Blake’s works that he decided were heretical.
