The English version mentions that too:

Also, from this book:

Talking about one of the first practical guides/manuals on how to do double-entry accounting.
"Pacioli was given a ten-year copyright on the initial publication and in 1508 he petitioned the Venetian Senate for a twenty-year copyright on any reprint of the original 1494 edition, which he was granted. This made him one of the first writers to be granted literary copyright."
Highly interesting read, by the way, despite a dull sounding subject.
For those interested, a readable summary of the history of copyright can be found at: http://questioncopyright.org/promise
Falkvinge himself also has a multi-part history of copyright blog series, found at: http://falkvinge.net/2011/02/01/history-of-copyright-part-1-...
So when it appeared in 15th century Venice as a means to encourage authorship, we are to presume that it was Dr. Who who brought it there?
Your history of copyright source is - I'm guessing - likely to be a little bit biased.
Really nice video on this _exciting_ topic btw
