Olivier Defaux studied Ancient History at the Université Lumière Lyon 2 and was PhD student in History of Ancient Science at the Humboldt University and the Excellence Cluster Topoi in Berlin. From 2016 to 2020 he was research fellow at the Max Planck Institute for the History of Science in Berlin. His main research interests include ancient geography and astronomy, as well as the philology and history of ancient and medieval scientific texts.
Greek Chronological Tables from Ptolemy to The Late Byzantine Period
My project will investigate the Greek chronological tables found in the manuscripts of Ptolemy’s Handy Tables. These tables cover different aspects of time computing and calendar synchronization useful to perform astronomical computations. Some of these tables were created after Ptolemy, during Late Antiquity and the Byzantine period. Historians of sciences still lack a modern complete edition of this set of chronological tables. On the basis of the most ancient manuscripts, I want to edit the tables that are still unpublished, and study their creation, their use and transmission during the Middle Ages.
