This painting by Francois Fleury-Richard shows a scene from the children’s fairy-tale “Little Red Riding Hood.” The illustration dates to about 1820, which is centuries after the original story developed.

If you haven’t read about the Tulsa Race Massacre of May 31/June 1, 1921, I recommend learning about it.

It also showcases the critical role that historical memory plays in
