Reading Mathematical and Astronomical Texts

“Degrees and Their Subdivisions in Pachymeres' Astronomy (Syntagma.4)”

by Carole Hofstetter (Université Paris Cité, CNRS, UMR 7219 SPHERE)

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.
