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.

Most authentic book compilation on the Oregon Trail I ever read. The way the diaries are brought to life from over 170 years ago is a remarkable achievement. Top book of year so far for me for today June 01, 2024 review Candice
This author is a breathe of fresh air in a world of lies and coverups. He brings ancient writings and new science to bring light to mankind. In this amazing work, the well known plato stories from antiquity are now put alongside this new discovery of tablets from beginning of time. This is the most complete explanation of Atlantis every brought to the public. Shame on the governments of Egypt and the world for hiding WHO BUILT THE PHYRAMIDS OF GIZA AND THE SPHINX. Once I read this book I knew why they hid this knowledge. They don't want a population to know how great the world used to be compared to know.
Randomly stumbled upon this book and I am shocked that I haven’t heard about it before. It’s hands down the best story I’ve read in years. People need to read this book. It needs to be turned into a book. This story is just plain awsome. M
This soulful book of personal poetry brought me into the past and into the present---and into my heart.
Read the first book and this 2nd one did not disappoint! Loved every chapter. More please!
