Annotations In addition to having a fabulous binding (clasps intact!) this volume contains notes and annotations in several early hands including one note signed and dated 1563. Some appear to be biblical commentary (or notes on sermons?).
Moving parts Oh, and if all that isn’t enough…The astronomy text includes moving, woodcut illustrations known as volvelles.
Students of theology, students of the history of science, students of book history: Enjoy!
Sphaera Mundi deals with the shape and apparent movement of the earth and other heavenly bodies and today is accounted the single most influential astronomy text ever published. This text and works subsequently informed by it would have been an essential tool for any medical astrologer, as an exceptional knowledge of the movement of planets and stars was a prerequisite for such a practice.
