The Jubilee Bull of Pope Boniface VIII for the Year 1300

This is another document that has a date on it. I can't find the Latin source anywhere online, but it seems pretty clear that there is a document.

There is a document 42.6 x 55.3 cm, font "diplomatic minuscule" (very neat handwriting), featuring the papal seal and silk filaments.

And the document has an exact date on it:   February 22, 1300

The holy year of jubilee : an account of the history and ceremonial of the Roman jubilee by Thurston, Herbert, 1856-1939

I find this very believable since 1300 is a nice round number.  Furthermore, this seems like this is very good proof that Pope Boniface VIII was in Rome prior to the years of the Avignon papacy. 

I think this pretty much kills the main part of the Fomenko "New Chronology" theory.  However, there is still the question: was the Julian calendar adopted at some point in the middle ages?

Update: A related document is the "Unum Sanctum", which supposedly has a date on it, November 18, 1302, but I find this less believable because it isn't in the body of the text.  Anyways, this was very controversial because of its proclamation of papal supremacy and it provoked quite a backlash, which is why the popes moved to Avignon. Again, good proof for Boniface.
