(forthcomming) "Printing the 'Tables of King Alfonso'"
in José Chabás, Richard Kremer, Matthieu Husson (eds.), Alfonsine Astronomy: Studies and Sources 3. Turnhout: Brepols
This chapter explores the printed editions of the "Tables of King Alfonso", in the context of a book closing the ERC project dedicated to the study of these tables.
Composed in the 14th century on the basis of previous materials, this set of tables was the main material used by astronomers of this period to compute most of their predictions.
This set was printed six times between 1483 and 1641.
In studying these editions, I am trying to show that the "Tables of King Alfonso" as an editorial object evolved as they were handled by different generations of printers.
This evolution testifies for lively reflections around astronomical models, which contrasts with the apparent stability of the numerical parameters shown in the tables.

Softwares and String Figures
(Approches historiques, philosophiques et anthropologiques du nombre, de la mesure et de la mesurabilité)
Abstract
At least since the fifth edition of Walter William Rouse Ball's Mathematical Recreations and Essays published in 1911, the making of string figures has been studied as a kind of mathematical activity.
Analyzing people's performances in making string figures, we can identify this activity as the finite execution of a discrete sequence of operations, where each operation transforms the configuration of the string.
Writing down the finite sequence of instructions corresponding to these operations therefore allow us to define a program or a routine of string figure-making
Trough the example of different routines used to produce a same "Owl" figure, this communication will explore the significance of such a description of string figures with their programs.

Seminars and events I organise
Lecture de textes mathématiques anciens
(Sphere)
This seminar is articulated around one primary source's short presentation explaining problems it raises, followed by the reading of this source edited and translated. One sessions lasts up to three hours, and is led by established researchers or graduate students.
Working language is either French or English depending of the situation.

Clément Cartier, Enseignement instrumenté des mathématiques: le cas de Richard de Wallingford
The collaborative research project EIDA associates a research team in computer vision from the laboratoire d'informatique Gaspard Monge (UMR 8049) and the team of historians of astronomy from the laboratory Systèmes de référence temps-espace (UMR 8630), to think about the role and the circulation of diagrams in the history of astral sciences with the help of artificial intelligence. My doctoral researches on instruments used to compute eclipses allow my to contribute to this project with questions raised by this particular type of diagrams, sometimes articulated, which sometimes make up for a computing instrument.
Since 2017, the ALFA project was interested to the diffusion of the Alfonsine Table used by Latin-writing astronomers between the end of the 13th century and the middle of the 16th century. In the making of my master's thesis, I completed an internship in the laboratory Systèmes de référence temps-espace (UMR 8630) to study the printed editions of these tables, at the end of the considered period.
