Reading Mathematical and Astronomical Texts

with Agathe Keller

Description
Each session of the Reading Ancient Mathematical Texts Seminar opens with the short presentation of a primary source and the mathematical problems it raises, followed by the reading of this source, provided with an edition and a translation. One reading typically lasts 3 hours, mostly filled with constant exchanges where any naive question is welcomed. This allows us to think about the linguistic composition of the text, its philology, etc. I believe the value of this seminar is mostly to un-understand (that is, to “durstand”) the texts, and to bring to light many unsuspected questions they hold. Three hours is never enough to read large chunks of text, but taking this time always brings very rich and inspiring discussions. This richness comes, not only from the intrinsic value of the sources presented, but also by the diversity of participants, with both experienced researchers and beginner students who can bring their expertise based on diverse sources, and who always invite us to look at the texts with new and original perspectives.
