A Roman City… Hidden in the Amazon?

In 1754, a mysterious manuscript surfaced in Brazil’s National Library. It spoke of a lost city hidden deep in the jungle — with Roman-style arches, black stone columns, and strange symbols no one could read.

Or something far older… and stranger? This short uncovers the story behind Manuscript 512, the document that has baffled historians for centuries.
