ALFA in Collaboration

As a means to extend the circle of discussion on the history of astronomy, ALFA has actively constructed collaborations with neighbouring scholarly fields, in particular with the fields of Manuscript studies and History of mathematics.  These collaborations are linked to specific publications.

Center for the Study of Manuscript Cultures (Hamburg)

  • Brita, Antonella, Karolewski, Janina, Husson, Matthieu, Miolo, Laure and Wimmer, Hanna. Manuscripts and Performances in Religions, Arts, and Sciences, (De Gruyter, Link)

This collective publication is the result of the collaboration of ALFA with the Center for the Study of Manuscript Culture in Hamburg. It investigates in multiple contexts how manuscripts are shaped for and by performance, how they are ‘performers’ of some kind as well. For ALFA team members this collaboration was an occasion to reflect about ways to find clues of astronomical practices in the Alfonsine corpus at large.

ERC SAW, Mathematical Practices in the Ancient World

  • Karine Chemla, Matthieu Husson, Mathematical Practices in Relation to Astral Sciences (In preparation, 2024 vol. 1-2025 vol. 2)

These two volumes, in preparation, will be one of the major outputs of the ERC project SAW. They seek to weave new links between the history of mathematics and the history of astronomy on a deep methodological level and a broad range of sources from the ancient and medieval periods. Team members from ALFA contribute both to the methodological reflection and with specific case study and thus deepen their own understanding.

  • Agathe Keller, Matthieu Husson, Positive, negative special issue Historia Mathematica (in Preparation)

This special issue of Historia Mathematica revisits the standard historiography on a “emergence of negative numbers’”. It does so in particular, by extending the historical analysis beyond arithmetical and algebraic sources to astronomical ones and more specifically those of the Alfonsine corpus.
