The Grolier Codex, an ancient document that is among the rarest books in the world, has been regarded with skepticism since it was reportedly unearthed by looters from a cave in Chiapas, Mexico, in the 1960s, but a new study claims it is both genuine and likely the most ancient of all surviving manuscripts from ancient America.
For years, academics and specialists have argued about the legitimacy of the Grolier Codex, a legacy the authors trace in the paper. Some asserted that it must have been a forgery, speculating that modern forgers had enough knowledge of Maya writing and materials to create a fake codex at the time the Grolier came to light.
