File talk:Tommaso de‘ Cavalieri.jpg

  User:Chip-chip-2020 has deceptively claimed that the image was uploaded as under by a license CC-by-4.0. That license has simply lied misrepresented that source. In providing a source, he is misrepresenting the image. The upload summary saying that is uploaded from en.wikipedia.org (where no equivalent image exists) shows that it was deliberately deceptive. It is an obvious copy-violation.

The attempt to provide a date is absurd since, according to the British Museum, there are ongoing authenticity questions about the actual drawing. This concerns the authorship, the subject and the date (see the accompanying documentation for an entry for a drawing by Cavalieri). Chip-chip-2020's sources at the moment seem to be faked. It is hard to work out whether the source in the museum in Bayonne can be verified, mainly because it is of doubtful authenticity so labelled in a different way in their catalogue. Any confirmed by Michelangelo would be labelled as such. Mathsci (對話) 17:59, 10 January 2022 (UTC)

There is a complete online catalogue of drawings in the Musée Bonnat-Heleu. The ones by Michelangelo have their own category on Commons; and the users who have uploaded the files have used this online page. Searching for Michelangelo yields two pages. There is a documented entry for an image which is different from the tumblr image. It is zoomable, but cannot obviously be dezoomified with tiles. There is, however, a jpg file with reasonable resolution. The annotation of the image says, "Titre : Portrait présumé d'Andrea Quaratesi ; Portrait présumé de Tommaso de' Cavalieri", "Artiste : Daniele Ricciarelli da Volterra (dessinateur) ; Michele-Ange (dit), Michelangelo Buanarotti (dessinateur)".

Possible attribution has been discussed by the British Museum and the Bonnat Museum. In 2003 the art historian Paul Joannides suggested that the abraded drawing might be the portrait of Cavalieri by Michelangeli, mentioned by Vasari's Lives of the Artists; that is discussed by the British Museum and the Bonnat Museum, but with no conclusive attribution. Michael Hirst's book on "Michelangelo: The Achievement of Fame" appears as Plate 46.[1] Mathsci (對話) 10:06, 11 January 2022 (UTC)
