Senecan Geometry and Stoic Surfaces

By Mason Wheelock-Johnson, Lawrence University

At many points throughout his philosophical prose corpus, Seneca the Younger encourages his audience to “circumscribe” some part of their life for moral improvement: for example, at Ep. 122.3, Seneca advises Lucilius, circumscribatur nox et aliquid ex illa in diem transferatur, and at De Ira 3.11.2, Seneca makes anger the object of this circumscription (circumscribenda multis modis ira est).

Hybrid Mathematical Texts and Greek Intellectual Networks

By Nick Winters, Northwestern University

Whenever two groups working in the same field (be it mathematics or any other science) seem to contrast sharply with one another, an investigation into points of similarity is merited. In this paper, I will undertake an investigation of one such point in the history of Greek mathematics: the hybrid systematist-heurist texts. It has been shown in a recent dissertation (Winters 2020) that two distinct schools of Greek theoretical mathematicians, dubbed “systematists” and “heurists,” can be observed in the textual record.
