      abstract = {This open access book explores commentaries on an  influential text of pre-Copernican astronomy in Europe. It  features essays that take a close look at key intellectuals  and how they engaged with the main ideas of this  qualitative introduction to geocentric cosmology. Johannes  de Sacrobosco compiled his Tractatus de sphaera during the  thirteenth century in the frame of his teaching activities  at the then recently founded University of Paris. It soon  became a mandatory text all over Europe. As a result, a  tradition of commentaries to the text was soon established  and flourished until the second half of the 17th century.  Here, readers will find an informative overview of these  commentaries complete with a rich context. The essays  explore the educational and social backgrounds of the  writers. They also detail how their careers developed after  the publication of their commentaries, the institutions and  patrons they were affiliated with, what their agenda was,  and whether and how they actually accomplished it. The  editor of this collection considers these scientific  commentaries as genuine scientific works. The contributors  investigate them here not only in reference to the work on  which it comments but also, and especially, as independent  scientific contributions that are socially,  institutionally, and intellectually contextualized around  their authors.},
