What´s the correct date?--Kaktus Kid (talk) 18:02, 25 June 2011 (UTC)

Reference Needed
The last paragraph of this article says "A proof of the Pythagorean theorem ascribed to Leonardo da Vinci is now claimed to have been authored by Mayer in 1772." but there is no reference for this claim. Can someone provide a reference please? 69.206.187.221 (talk) 02:07, 4 October 2018 (UTC)
