Interestingly, CapriUni, this is sort of related to the Breton story about Ugly Jan mentioned by LadyJean. I started a thread on the Breton werewolf legend of Cunmar the Accursed, said to be one of the real-life inspirations behind "Bluebeard". Maybe "Bluebeard" counts as a tale about disability? Or "Silvernose", a similar Italian tale? The devil's prosthetic nose was there for a reason.
