Jacques Lefèvre d'Étaples (Latinized as Jacobus Faber Stapulensis) was a French theologian and a leading figure in French humanism. He was a precursor of the Protestant movement in France.
I: Arithmetica decem libris demonstrata, the De elementis arithmetice artis of Jordanus Nemorarius (Jordanus de Nemore) with commentary and demonstrations, first published in 1496
II: Musica
III: The arithmetic of Boethius, a translation of the 'De institutione arithmetica libri duo' by Nicomachus of Gerasius.
IV: In 'Rithmimachie ludus', a smal opusculum of five pages, printed at the end of the second edition of the Arithmetica of Jordanus Nemorarius, Lefèvre gives a very curious description of this ancient Pythagorean game, but with such little detail that one cannot understand it properly except by joining it to the extended notice which Boissière gave to the same game
