Note 249 — 29 THE BOY AND THE MANTLE
Reading edition
In the Contes à rire, p. 89, a sylph who loves a prince gives him a flower and a vase which will blacken upon his wife's proving unfaithful: Legrand, 1779, I, 78. I have not seen this edition of the book, but presume that this tale is entirely akin with the above.
