Lvcretivs, the issue with Pompeii painting shows that there are 2 theories that can exist. Mr Zhukovsky was not 'conspiracy' author, but very influential botanist. I do not want to say that if he says smth that it is absolute truth, but that he had an experience and knowledge to state that. Where is the truth? Who is right, Cassela and Zhukovsky or their opponents? I really doubt they didn't knew about pines.

The chief argument against the theory why couldn't Romans or other Mediterenians be in Americas is "it is impossible because it is impossible". That is way any argument starting with paintings in Pompeii and ending with archaeological findings in America can not be truth because "it is impossible".

You convinced me with Scipio travel, but what about all those findings? Also currents and routes that used Columbus might be used at any historical time, not only during Columbus live.

Ibrahim, you should know, that Thor Heyerdahl had not only Kon Tiki expedition. His Egyptian boat called Ra 2 (this picture http://ru.wikipedia.org/wiki/%D0%A4%...I.InMuseum.jpg compare with Kon Tiki http://ru.wikipedia.org/wiki/%D0%A4%...kiInMuseum.jpg). You can read his book about this expedition or just google it.

Speaking about Lemon, it's motherland is India and China, not Spain.

To reach Azores you can not hold shores. It means that people could find them without holding any shores using stars for navigation may be, it means that they were able to find other distant land with stars, or smth.

Cracking down ships... well, not everyone believed that papyrus boat can survive the transatlantic voyage. Also some man in 1976 sailed through the north Atlantic ocean on small boat made of bull skin. And he did it.

How to explain archeological finding in America, that evidence the Roman or other pre Columbu visits?
