More Tanith Lee. This one's from her epic fantasy "The Birthgrave." The heroine of the story wanders around her primitive fantasy planet with a mask on because she is really an alien with amnesia and her face doesn't look human enough to pass for human, so she has to keep the mask on even if she doesn't remember why. This "big scene" (on a little panel) depicts the heroine received as a Goddess by a royal court somewhere. The setting is taken wholesale from Piranesi with only a few things changed to match the book's details. The Goddess is the tiny figure in light green at the top of the stairs in the center.
