The Two Dianas (French: Les Deux Diane, 1846) is a novel written by Paul Meurice, a friend and collaborator of Alexandre Dumas, père. Dumas agreed to put his name on the work to increase sales, but had no hand in actually writing it. It tells the fictionalized story of Gabriel, comte de Montgomery, who mortally wounded king Henry II of France in a jousting accident. The two Dianas in the title refer to Henry II's favorite, Diana de Poitiers, and Diana de Castro, who was believed to have been her daughter at the time the novel was written. The novel also includes a fictionalization of the Martin Guerre story.
