Roger Bacon’s essay on natural philosophy, experimental science, and magic, Letter on the Secret Powers of Art and Nature, and on the Invalidity of Magic (ca. 1270s), contains almost all of the alchemical ideas that were later attributed to Bacon in the Elizabethan text, The Mirror of Alchimy, as well as speculative technology, and a detailed discussion of necromancy. In this short work Bacon explained his concept of scientia experimentalis, which he proposed as a way of harnessing natural forces to produce stunning and useful effects. Bacon used alchemy as an extended example of the promise of technology to surpass natural limits. Bacon’s ideas about the power of human art, or technology, are central to his reputation as an alchemist and a necromancer in the late 16th century, and to understanding the complex intellectual connections between medieval natural philosophy, magic, and technology and early modern natural philosophy and alchemy.

About Brown Bag Lectures


Brown Bag Lectures (BBLs) are a series of weekly informal talks on the history of chemistry or related subjects, including the history and social studies of science, technology, and medicine. Based on original research (sometimes still in progress), these talks are given by local scholars for an audience of CHF staff and fellows and interested members of the public.
