Abstract

In [1929a], Louis Karpinski published a short description of “The Italian Arithmetic and Algebra of Master Jacob of Florence, 1307”. Around one third of the note describes the algebra chapter of the treatise, pointing out among other things that Jacopo presents the algebraic “cases” in a different order than al-Khwārizmī, Abū Kāmil, and Leonardo Fibonacci, and that the examples that follow the rules also differ from those of the same predecessors. Karpinski did not mention explicitly the absence of geometric proofs of the rules, nor that the examples differ from those of the other authors already in general style, not only in detailed contents; but attentive reading of Karpinski’s text and excerpts from the manuscript leave little doubt on either account.
