Early Renaissance painter Piero della Francesca was also an accomplished mathematician, and his book on polyhedra, De quinque corporibus regularibus (new Wikipedia article https://en.wikipedia.org/wiki/De_quinque_corporibus_regularibus) has an interesting history that deserves to be better known. Rediscovery of the mathematics of Archimedes! "First full-blown case of plagiarism in the history of mathematics" (by Luca Pacioli, in Divina proportione)! Maybe owned by John Dee! Long lost and found centuries later in the Vatican Library!
