From a Living Cosmos to an Infinite One, Bruno's Debt and His Trial

Yates traces a direct line from the Asclepius's praise of the cosmos as a living, divine second god to Giordano Bruno's cosmology two centuries later, and the connection was not merely thematic. Bruno read the Hermetica as genuinely ancient Egyptian wisdom, prior to and superior to Greek philosophy, an assumption the whole Renaissance shared before Casaubon's philological dating overturned it, and he treated the Hermetic vision of a cosmos worthy of religious reverence as license to press the idea further than the Hermetica itself had gone. Where the Asclepius calls the world a beautiful, living second god within a bounded cosmos, Bruno argued for an infinite universe filled with innumerable worlds, each one, on his reading, entitled to the same reverence the Hermetic texts had extended to the cosmos as a whole.

Yates reads Bruno's 1600 execution in Rome as bound up with this Hermetic inflected cosmology and its religious implications for orthodox doctrine, not simply with the astronomy in isolation, since an infinite universe of innumerable worlds sat awkwardly beside a unique incarnation and a unique creation. Her account has been challenged by later historians who weight other elements of Bruno's trial more heavily, but the underlying textual debt is not contested, Bruno's own writing draws explicitly and repeatedly on Hermetic cosmology, giving the Asclepius's second god its most consequential and most dangerous afterlife.
