By comparing physical structures, GIS-based viewsheds and computed skyscapes of several roundels throughout central Europe, we attempted to understand the spread of knowledge transfer within the “Kreisgraben-phenomeon” of the early 5th millennium BC.
This project investigated how new knowledge emerges from the originally separate traditions of astronomy, astrology and mathematics in a transformation and innovation process. The investigations are based on the research results obtained in research group (D-1) Space of Nature.
This project traces the evolution of 18 constellations along the ecliptic which around 400 BCE formed the 12 zodiac signs we know today.
The project concerned the history of positional astronomy from the Babylonian sources to their reception by Hipparchus and Ptolemy.
In this project the transformation and diffusion of ancient science was investigated with a focus on two key periods of change: a formative period, 400–330 BC, during which mathematical astronomy developed in Babylonia; a subsequent expansive period, 330 BCE–500 AD, during which there was a marked increase in the exchange of scientific knowledge and practices between Babylonia and its neighbouring cultures in the eastern Mediterranean region.
In this project various operational, mathematical, astronomical, conceptual and theoretical aspects of Babylonian mathematical astronomy were investigated. Babylonian mathematical astronomy comprises about 440 cuneiform tablets and fragments from the Achaemenid, Seleucid and Parthian eras of the Late Babylonian period (400-50 BCE). The tablets were found in Babylon and Uruk, two main centers of Babylonian science.
