Dot Porter, Curator, Digital Research Services at the University of Pennsylvania Library, offers a video orientation to Penn Library’s LJS 267, De ludo scacchorum seu de moribus hominum et officiis nobilium … [etc.]. This manuscript was written in Italy in 1409, in Latin, with a few poems in Italian. It is a compilation, mostly in Latin, of religious, literary, historical, and natural-historical works, including classical and contemporary selections, as well as letters by humanist writers Francesco Petrarca and Donatus Albanzani. Over a quarter of the manuscript is devoted to the De ludo scachorum of Jacobus de Cessolis, a collection of sermons about the proper relationships between a king and various classes of subjects, compared to the rules of chess.
