Mansions: A Romance of the Tropical Forest (1904) is an exotic romance by William Henry Hudson about a traveller to the Guyana jungle of southeastern Venezuela and his encounter with a forest-dwelling girl named Rima. Hudson based Rima and her lost tribe on persistent rumours about a tribe of white people who lived in the mountains.[2] Temple paintings often showed light-skinned people, and Spanish Conquistadors were at first thought to be gods. Green Mansions also features some cryptozoological concepts such as Curupita (Curupira) and Didi purportedly representing giant apes unknown by science. Many authors of the time also recounted "lost worlds" and "lost tribes", the most successful being H. Rider Haggard, Edgar Rice Burroughs, Robert E. Howard and Arthur Conan Doyle. Hudson's book has endured as literature because of its evocative and lyrical prose, and his naturalist's keen vision of the jungle. Rima also exemplifies the "natural man", a philosophical notion put forth by Jean-Jacques Rousseau and others, that someone raised away from corrupting civilisation would be naturally pure of heart and attuned to their environment. Tarzan, raised by apes, and Mowgli, raised by wolves, are Rima's literary cousins.
