JFYI, there is a typo in the linked to text, Benedetto Portinari, it's the same Florentine family of Beatrice Portinari, he was the nephew of the more famous Tommaso Portinari: https://en.wikipedia.org/wiki/Tommaso_Portinari https://en.wikipedia.org/wiki/Tommaso_Portinari The "graphical rendition" on the original site has it correct: http://www.npr.org/sections/krulwich/2011/11/18/142467882/leonardos-to-do-list http://www.npr.org/sections/krulwich/2011/11/18/142467882/le... BTW - still to be picky - the linked article is 2014, whilst the original article by NPR's Robert Krulwich is 2011.
