The Indiscreet Jewels is the first novel by Denis Diderot, published anonymously in 1748. It is an allegory that portrays Louis XV as Mangogul, Sultan of Congo, who owns a magic ring that makes women's vaginas ("jewels") talk. The character of Mirzoza represents Louis XV's mistress Madame de Pompadour. Diderot portrayed Pompadour in a flattering light in The Indiscreet Jewels, most likely to ensure her support for his Encyclopedie.
