In this episode we talk to Samuel Gessner about the armillary sphere, an interesting astronomic instrument with astrological applications. Samuel explains the role and functions of these spheres, often used as teaching tools in medieval universities. He demonstrates some of its applications in astrology. Samuel is a post doctoral researcher at the ERC ALPHA project, Observatoire de Paris.
We thank the IMCCE Observatoire de Paris for making available the armillary sphere
