Note 46 — Traditions of Dwarf Races in Ireland and in Switzerland [45]
Reading edition
May it not be that Cinderella's glass shoe was really green and derived its name from the Irish word glas, denoting that colour, which is familiar to us in place-names? I make this conjecture with diffidence. I know the usual explanation is that the shoe was made of a kind of fur called in Old French vair, and that a transcriber changed this word into verre. Miss Cox, in her "Cinderella," mentions that she had only found six instances of a glass shoe. As Littré says in the article on vair in his Dictionary, a soulier de verre is absurd. A fur slipper, however, does not appear very suitable for a ball.
