Joseph François Michaud has written in the 3 volume work entitled, “History of the Crusades”, some very interesting information. 
On page 182, in volume 2, Michaud writes about the enrichment of the fields and gardens of France and Italy by the introduction of some plants that were before that time unknown in Europe.
What is absolutely amazing about this section of the History of the Crusades is that the exclusive American crop known as maize is mentioned on page 183 (see screenshot above). 
The bringing of American MAIZE to Italy between the years of 1150 and 1207 A.D.?
That has to mean that the lands of the Crusades were the Americas! Everyone knows that corn, in this case, maize, was only grown in the Americas during ancient and biblical and medieval times. Corn In The Bible® is here.

I was reading the above passage and the part that says the magistrates called down a blessing from a production of Greece that would one day cultivate Italy is this a reference to Greece being in America also ?
Yes, Roe. Ancient greece was at Central America and the Yucatan Peninsula. The Greek Islands were the Caribbean Islands.
