Manuscript 512
Manuscript 512 (Portuguese: Manuscrito 512) is a ten-page manuscript of dubious veracity and unknown authorship that relates the discovery of a "lost city" in Bahia, Brazil by a group of bandeirantes in 1753. Originally found in 1839 at the National Library of Brazil, where it is kept to this day, the document tells of a group of Portuguese adventurers who searched for a long time the legendary mines of Muribeca, traveling for about ten years in the Brazil's jungle.
