I just recently read a book, about William Sinclair and Carlo Zeno's supposed trip across the atlantic to north American. Some historians, do not believe this happened but to me it made a very good case.
In the debate for which european explorer "discovered" North America often people have strong national biases, but I was curious what the people on the forum think about the debate of discovering America.
The book mentioned Phoenicians, Celtic, Roman, Egyptian, Welsh and Vikings traveling to North America before Christopher Columbus.
Although I can't be certain, I think the vikings certainly were in North America before Columbus and I think probably a lot of other cultures have had been to north america too. Perhaps they settled and integrated in the indian populations or perhaps they kept it secret to take advantage of trade. In my opinion William Sinclair did have a successful trip to North America.
Was a Roman or greek ship really incapable of going across the atlantic ocean?
