Jacobus de Cessolis
On the second half of the 13th century, Jacobus de Cessolis, a Dominican monk in Cessole (Asti district, Piemonte, Northern Italy) used chess as the basis for a series of sermons on morality. They later became Liber de moribus hominum et officiis nobilium super ludo scacchorum ('Book of the customs of men and the duties of nobles or the Book of Chess'). The popular work was translated into many other languages (first printed edition at Utrecht in 1473). Chess historian Harold Murray asserts that the popularity of the work rivaled "that of the Bible itself." The work was the basis for William Caxton's The Game and Playe of the Chesse (1474), one of the first books printed in English.
