>Michael Storch - Applied Imagination: Giordano Bruno and the Creation of Magical Images (2007)
>The creation and manipulation of infinite images is central to Bruno' s thought, but to the best of my knowledge, this has never been properly treated before. This project is a departure from much of the current scholarship on Bruno which has focused on his contribution to scientific thought, and downplayed or ignored the Hermetic and magical elements which pervade his work. Each chapter deals with different works of Bruno, and different aspects of his philosophy, and each is rooted in the larger project of uncovering the role, meaning, and application of images in Bruno' s thought.
