De ludo scachorum (English: On the Game of Chess), also known as Schifanoia ("Boredom Dodger"), is a Latin-language manuscript on the game of chess written around 1500 by Luca Pacioli, a leading mathematician of the Renaissance. Created in the times when rules of the game (especially the way queen and bishop move) were evolving to the ones known today, the manuscript contains over a hundred chess problems, to be solved – depending on the problem – using either the old or the modern rules.
