During the renaissance science was never separated from mysticism and alchemy. Some of the finest minds such as Leonardo da Vinci and Isaac Newton were all heavily involved in what they would of called the mystic arts. This is a fascinating guide to the less well known pioneers of scientific discovery, including Meister Eckhart, Nicholas of cusa and Giodarno Bruno. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
