The project Zodiac - Ancient Astral Science in Transformation (ERC) at the Institute for the History of Knowledge of the Ancient World, Freie Universität Berlin, is hosting a workshop on 11–12 April 2024:

 

Astronomical Computation in the Pre-Modern World: Methods – Tables – Accuracy

Fabeckstraße 23–25, room 2.2058

14195 Berlin

Convenors: Mathieu Ossendrijver and Thomas Peeters

 

This workshop brings together specialists of predictive methods in pre-modern astronomy. The focus is on zodiac-based computational methods in ancient Babylonia, Egypt, and the Greco-Roman world (ca. 400 BCE – 400 CE) and pre-modern computational methods in other regions, communities, and periods (ca. 400–1500 CE).

Topics of discussion:

  • New approaches and results in the area of table cracking and reconstruction of algorithms
  • Interpreting a multiplicity of predictive methods
  • Accuracy and efficiency of astronomical computation
  • Predictive toolboxes
  • Astronomical tables: notations, layout, non-textual features, material features
