Glass slipper
In short: The shoe that reveals Cinderella’s identity in Perrault’s telling.
Object
How does it work in the tale?
The ball’s appearance fades, yet the slipper remains. Trying it on turns a memory into evidence. The golden shoe plays the corresponding role in Grimm.
Why does the slipper count as evidence?
In Perrault, the slipper is tried from house to house. When it fits Cinderella, she produces its partner. The object left behind at the ball is reunited with the one she kept. Follow the two slippers from the moment they separate to the moment they come together again.
