Discovered near Lake Titicaca in Bolivia, the Fuente Magna Bowl has been described as one of the most controversial artifacts in South American archaeology. Its interior markings resemble ancient Near Eastern script, leading some to claim it proves transoceanic contact between Mesopotamia and the Americas thousands of years before Columbus.

But is that claim supported by evidence?

In this episode of History Undisclosed, we take a careful, critical look at the Fuente Magna Bowl — its discovery, its inscriptions, the scholars who studied it, and the serious doubts surrounding its authenticity. We examine why the artifact became a favorite in alternative history circles, what professional archaeologists say about it, and how gaps in provenance can turn a single object into a global mystery.

In 1513, an Ottoman admiral named Piri Reis created a world map that initially puzzled the world. The map appears to depict parts of South America with surprising accuracy, and according to some claims, even shows Antarctica centuries before it was officially discovered. In this deep dive, we examine the real history of the Piri Reis Map, where its source material came from, how it was constructed, and why it became a magnet for speculation, pseudohistory, and fringe theories. Using historical knowledge and scholarship, we separate what the map genuinely tells us from what later generations wanted it to say. Was this evidence of lost ancient knowledge? A misunderstood Renaissance artifact? Or a case study in how modern myths are built around historical objects?
