Letters on Natural Magic; Addressed to Sir Walter Scott, Bart.

"Letters on Natural Magic; Addressed to Sir Walter Scott, Bart." by Sir David Brewster is a scientific publication written in the mid-19th century. The work explores the concept of Natural Magic, discussing how ancient governments and magicians used scientific principles to deceive their subjects and establish a sense of supernatural authority. Brewster aims to dissect various phenomena attributed to magic by examining their scientific underpinnings. At the start of the publication, Brewster introduces the concept of Natural Magic, emphasizing its historical significance and connection to human credulity. He outlines how ancient rulers manipulated scientific knowledge of nature to maintain power and influence through seemingly miraculous occurrences. The opening letters set the stage for a deeper examination of illusions related to optics, acoustics, and other scientific principles that fueled beliefs in magic and supernatural phenomena, revealing the intricate relationship between science and deception throughout history.

Sir David Brewster KH PRSE FRS FSA Scot FSSA MICE was a Scottish scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in physical optics, mostly concerned with the study of the polarization of light and including the discovery of Brewster's angle. He studied the birefringence of crystals under compression and discovered photoelasticity, thereby creating the field of optical mineralogy. For this work, William Whewell dubbed him the "father of modern experimental optics" and "the Johannes Kepler of optics."
