“Will Christopher Columbus's picture soon adorn the walls of many Lithuanian-American, Polish-American, and Portuguese-American institutions as well as private homes of people of this background?” questioned the organizers of a similar talk held last month at the Balzekas Museum of Lithuanian Culture in Chicago. Mr. Rosa’s research suggests that it should. During his presentation, he will show historical evidence indicating that the man credited with discovering America was not the son of a humble weaver from Genoa, but rather a nobleman of Portuguese birth fathered by the exiled Polish King Wladislaw III, a member of the Lithuanian Jagiellonian Dynasty.
While Mr. Rosa’s theories have been met with skepticism by many, they have also received considerable praise. At a presentation that took place on May 16, 2012, at the Portuguese Academy of History, which was full to capacity with members of the scientific community, his investigations were described as "a serious look at the truth, well-substantiated and worthy of praise." Similarly, his book Portuguese Columbus—New Revelations received accolades from Portuguese academics, including Professor Manuela Mendonça, President of the Portuguese Academy of History, and Professor Joaquim Veríssimo Serrão ex-president of the same organization who wrote the preface to Colombo Português—Novas Revlações and described Mr. Rosa’s work as “serious and diligent.”
