Measuring space by time

Hoffmann, Susanne

Although there is no celestial map preserved from ancient Greece or Mesopotamia, there are several hints pointing to uranographies in both cultures. One of the most interesting questions is how those ancient astronomers measured the positions of celestial objects and the answer in many cases is time.

The poster presents a comparison of Greek and Babylonian frames of reference and together with my talk it shows the evidence the frames of reference provide for the measurement of time with the celestial sphere as well as the measurement of distances on the celestial sphere by time.
