The Indiscreet Jewels

Blurb

The Indiscreet Jewels is the first novel by Denis Diderot, published anonymously in 1748. It is an allegory that portrays Louis XV as the sultan Mangogul of the Congo who owns a magic ring that makes women's genitals talk.
A comparable trope that Diderot must have known is found in the ribald fabliau Le Chevalier Qui Fist parler les Cons.
