Calendar calculation document
This is picture of the middle of a big round table in the monastery of Rein that was used to document various astronomical calculations used for manufacturing the yearly calendar. I wouldn't pretend to understand any of it, but it definitely looks amazing. The underlying astronomical calculations were performed by the biggest astronomer living in Graz at the time - Johannes Kepler.
