Vladimir Nabokov's novel Ada or Ardor: A Family Chronicle (1969) deals very heavily with the incestuous relationships in the intricate family tree of the main character, Van Veen.Other works of literature show consequences not so grave, such as Arundhati Roy's The God of Small Things, in which fraternal twins share a cathartic sexual experience. In Gabriel García Márquez's One Hundred Years of Solitude (1967) there are several cases of sex between more or less close relatives, including that which occurs between a nephew and aunt.According to Paul Di Filippo, Delany sought to push the boundaries of heteronormative sex. Delany's novel Hogg, written in 1969, is also full of detailed descriptions of incest. The book debates cousin coupling at a time when it was a highly contested topic. Cousins (1879) by Lucy Bethia Walford, a fictional story of Simon who romances his cousins.The 120 Days of Sodom (1785), Philosophy in the Bedroom (1795), and Juliette (1797), all written by the Marquis de Sade, are all full of detailed descriptions of incest.John Ford's 'Tis Pity She's a Whore play (between 16) is one of the earliest examples that generated much controversy.
