De ludo schacchorum seu de moribus hominum et officiis nobilium ... etc.

Kislak Center for Special Collections, Rare Books and Manuscripts, LJS 267. Italy, 1409. 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 (f. 1r-56r). Other moderately substantial texts include descriptions of various geographic regions from Honorius of Autun's De imagine mundi (f. 61r-71r); a brief history of the Roman civil wars (f. 71v-92r); and the Computus of Bono da Lucca, which deals with the calendar, lunar cycles, and calculations for determining the date of Easter (f. 109r-124v). The manuscript is a palimpsest, with the lower text from the 14th century, probably legal. Penn Libraries Catalog: go to Find
