- De ludo scacchorum
"De ludo scacchorum" ("On the Game of Chess") is a
manuscript on the game ofchess written around 1500 byLuca Pacioli , a leadingmathematician of theRenaissance . The manuscript presents over 100chess problem s. Long thought to have been lost, the manuscript was rediscovered in 2006, in the 22,000-volume library of Count Guglielmo Coronini. Based onLeonardo da Vinci 's long association with the author and his having illustrated Pacioli's "De divina proportione", some scholars speculate that Leonardo either drew the chess problems that appear in the manuscript or designed the chess pieces used in the problems.References
