The Sphaera Project at the Max Planck Institute for the History of Science in Berlin is pleased to present its new website and online database. Led by Senior Research Fellow and Research Group Leader Matteo Valleriani, the team examines knowledge system evolution and shared scientific identity by studying Johannes de Sacrobosco's 13th-century text,  De sphaera. His handwritten treatise covered geocentric cosmology through "simple, late medieval description...based on the Aristotelian and Ptolemaic worldviews," becoming mandatory reading in European universities for centuries.

Developed by Florian Kräutli, the open access database allows researchers and members of the public alike explore the bibliographic data of 320 books that contain, or are related to, the text by Sacrobosco. The system covers books published between 1472 and 1650. Additional works and records will be added to the collection shortly.
