I found something...

[ReneZ]

Not if it is Italian, paper would have been more likely in Germany, parchment in I.. As a matter of fact it is one of the reasons why I (and I suppose some others) think it is Italian.

Just to be sure, this is about the single sheet found by Fabrizio Salani.

The proposed explanation that this would be a copy made by Barschius in Prague in the 1630's is very problematic, considering the fact that it is on parchment.
This issue also applies to many other potential explanations of this page.

A "modern" practical joke is not excluded by this.

(Please note that I specifically do not wish to suggest that Fabrizio would be involved in anything like this. I am sure that he is completely honest about this find).
