The Slippers of Cinderella

A young woman in a white dress, with a feathered bow in her hair, is seen from the side as she stands in a park. This illustration comes with the following caption, attributed to Hector Sandus:

For you must have all heard of the Princess Cinderella with her slim feet and shining slippers. She was beloved by Prince ******, who married her, but she died soon afterwards, poisoned (according to Dr. Gerschovius) by her elder sister Arabella, with powdered glass. It was ground I suspect from those very slippers she danced in at the famous ball. For the slippers of Cinderella have never been found since. They are not at Cluny.
