PREFACE.

About ten years ago, when I was beginning to study Latin writers and was eager for mathematical knowledge, I began to devote my attention to Boethius. Not long after, Halm Karl Felix Halm (1809–1882) was a prominent German philologist and librarian who mentored Friedlein. was the one who encouraged me to apply myself more intensely to Boethius's mathematical works in particular. He believed that some benefit for a more accurate understanding of the Latin language could be derived from this source as well. However, I first believed I could produce useful results in the field of arithmetic, and I made my findings public in a short book published on the geometry of Boethius. The most learned man Moritz Cantor Moritz Cantor (1829–1920) was a foundational figure in the history of mathematics; his critiques often spurred further research in the field. challenged my views and urged me to attempt to refute, with the most certain arguments possible, the incorrect conclusions he had reached regarding Boethius's art of reasoning and calculating original: "arte ratiocinandi et computandi." This refers to the methods of logical deduction and numerical calculation used in the early Middle Ages.. I also presented a few points regarding the Geometry of Boethius to demonstrate that it did not actually originate from Boethius himself Friedlein is engaging in a 19th-century scholarly debate about whether the geometric texts attributed to Boethius were authentic or later medieval fabrications..
