Another nutty conspiracy theory!! That’s what I first supposed. I now believe Columbus is guilty of a huge fraud.

Dr. Rosa’s lecture presents evidence that Columbus was a Polish Prince, not an Italian weaver!

Regarded as the world's foremost authority on Christopher Columbus, Dr. Manuel Rosa received his PhD in Insular and Atlantic History (XV-XX Centuries) at Azores University with the dissertation CRISTOFORO COLOMBO versus CRISTÓBAL COLÓN. The investigation proved that the Italian weaver from Genoa, touted as being the navigator, was not the same person as noble navigator from Iberia.

This groundbreaking research was preceded by many books published internationally and hailed as history changing. The books exposed Columbus as a secret agent at the service of Portugal deceiving Spain with a false route to India in order to safeguard the real route for Portugal. Columbu’s secret mission was a success!

Dr. Rosa's own "voyage of discovery" began during the Columbus quincentennial, when his doubts were stirred by the marriage of a supposedly lowly foreign weaver to a highborn Portuguese lady. Such a union might pass muster as a fairy tale today, but it would have been unthinkable in 1479. The closer Dr. Rosa looked, the more certain he became that he was looking at an intentional coverup. Before long his research was bearing results. Now, after 30 years of research, a new Christopher Columbus emerges. The 1492 explorer was not a peasant weaver, but a Polish Prince.

Dr. Rosa received the Boston Globe’s Art Merit Award in 1976, the Lockheed Martin Lightning Award in 2002, the American Institute of Polish Culture’s Special Recognition Award in 2015, and the MediaTravel Columbus Award in 2017. He has authored nine books on Christopher Columbus history and has appeared on BBC, NPR, the Travel Channel's "Expedition Unknown," and numerous foreign-language media. His work was featured on the cover of Newsweek’s Polish subsidiary in 2011. He served as advisor to UNESCO and the Haitian government on matters related to Columbus' lost ship, the Santa Maria.

He lectures on Columbus at American and European universities. (More)
