Modern fiction

In 1972, science-fiction author Philip José Farmer wrote Tarzan Alive, a biography of Tarzan using the frame device that he was a real person. In Farmer's fictional universe, Tarzan, along with Doc Savage and Sherlock Holmes, are the cornerstones of the Wold Newton family. Farmer wrote two novels, Hadon of Ancient Opar and Flight to Opar, set in the distant past and giving further knowledge of the antecedents of the lost city of Opar, which plays an important role in the Tarzan books. In addition, Farmer's A Feast Unknown, and its two sequels Lord of the Trees and The Mad Goblin, are pastiches of the Tarzan and Doc Savage stories, with the premise that they tell the story of the real characters upon which the fictional characters are based. A Feast Unknown is somewhat infamous among Tarzan and Doc Savage fans for its graphic violence and sexual content.
