The study demonstrates the gradual and independent development of overspecification and visual inaccuracies during transmission, highlighting their stability over multiple copies. Additionally, it explores errors in labeling and the introduction of spurious elements in diagrams, reinforcing the belief that these characteristics arise during the transmission process. The findings challenge the notion that these diagrammatic features were common practices confined to ancient and medieval times, showing that they persist into the 21st century.</div></div>","PeriodicalId":51061,"journal":{"name":"Historia Mathematica","volume":"71 ","pages":"Pages 34-58"},"PeriodicalIF":0.5,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first part of this article we focus on the controversies over the properties of the “proportional” helix line (<em>linea girativa</em>), invented by Richard Kilvington, who unambiguously described this line as an actually infinitely long geometrical entity. Many of his contemporary as well as later scholastic authors tried fervently to deny that conclusion, in spite of its mathematical consistency. In the second part of the article we present the geometrical arguments used against the atomistic theories appearing in Oxford natural philosophy at the beginning of the fourteenth century. These geometrical arguments were recognized by their authors as “more efficacious” in proving atomism false than logical or philosophical ones. On the basis of these discussions we finally present a few conclusions concerning the attitude of later medieval scholars about the usefulness of mathematical proofs in the context of Aristotelian natural philosophy.</div></div>","PeriodicalId":51061,"journal":{"name":"Historia Mathematica","volume":"70 ","pages":"Pages 53-72"},"PeriodicalIF":0.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
