In the ancient world, astronomers developed geometrical models to account for the motion of the celestial bodies. The earth in the center of the universe, they imagined the stars and planets to be located on rotating spheres around it, whose nested movement creates their individual paths in the sky.
The intricate designs of the ancient astronomical models prove difficult to grasp from verbal descriptions and illustrations alone, but become very evident by means of digital modeling and visualization.
With today’s technology, we have the possiblity to represent pre-modern astronomy in the way it was originally conceived – as “geometry in motion”.
With my project Modeling the Cosmos, I want to take digital approaches in the history of astronomy one step further. Key concepts in Digital Humanities are interactivity and real-time simulation, coming together in the form of encompassing digital environments.
My aim is to provide the history of astronomy with a Digital Research Environment to recreate astronomic simulations from the historical accounts. Technically fit to host planetary models from the ancient systems up to Keplers laws, my tool enables researchers to interactively study and explore the options and constraints of the historic sources.
In this function, the simulation will also aid in the digital reconstruction of lesser known historical astronomical models, whose functioning is only partially understood, such as the geometrical designs of the astronomers Giovanni Amico, Girolamo Fracastoro or Al-Bitruji.
