Requested move 27 April 2015
Why is this article so short, despite his notability and outstanding works. There are plenty of reliable sources on his life and contributions. If he is probably the most important Italian mathematicians, why do Joseph-Louis Lagrange's article contains much more information? Please extend this article. — Preceding unsigned comment added by 22.214.171.124 (talk) 11:50, 3 November 2015 (UTC)
For Italians who lived before 1861, nationality is synonymous of ethnicity: so, we define all of them as Italian, independently of the state where they were born. The same applies for Germans before 1870. Alex2006 (talk) 06:01, 19 November 2015 (UTC)
The "portrait" that the file description page on Commons claims to be by an "unknown medieval artist" (a contemporary of Fibonacci) is clearly no such thing.
The only source claimed there is a book from 1981, but it is most likely an imaginary portrait of the sort often printed in 19th century popular works on history. It has no particular historical or artistic value. It is used in a large number of Wikipedias, but the editors of the German article removed it already in 2006 (see Diskussion:Leonardo Fibonacci for the discussion). --Hegvald (talk) 07:02, 17 January 2016 (UTC)
- In some cases I can see how an artistic depiction of an event from someone's life might be helpful in an article even if there is no reason to believe that the person is depicted recognizably, but in this case it's just a headshot. We should remove it unless someone can dig up provenance showing it to accurately depict Fibonacci. —David Eppstein (talk) 07:28, 17 January 2016 (UTC)
For that matter, it may also be a copyright violation. I just checked my copy of Mathematical Circus, the 1981 book the artwork was scanned from. It just labels the image as being of Fibonacci, and gives no indication of how old it is or who it is by. So the default assumption should be that it has the same copyright as the rest of the book, which is still valid. —David Eppstein (talk) 08:23, 17 January 2016 (UTC):::
- Never mind, I found File:Fibonacci2.jpg which the Gardner book's copy seems to have been cropped from. It apparently dates to a mid-19th-century book, as Hegvald suggested. So not a copyvio, but still not useful as an image of the subject. —David Eppstein (talk) 08:28, 17 January 2016 (UTC)
