Aristotle and Huygens on Color and Light

Both before and after the publication of Isaac Newton’s particulate theory of light, numerous wave theories of light were advanced by both philosophers and scientists (e.g., René Descartes, Thomas Hobbes, Robert Hooke, Francesco Grimaldi, and Christiaan Huygens). What is peculiar about this list, as frequently found in the scholarly literature on light, is that it refers to individuals who do not extend much further back than the seventeenth century. A close examination of Aristotle’s account of color and light in comparison to Christiann Huygens' theory of color and light, however, reveals that Aristotle deserves to be recognized as one who antedates and foreshadows these modern wave theorists. Indeed, we shall argue that Aristotle offered the first wave theory of color and light. On Aristotle’s theory, light is the actualization of a transparent medium such as air or water that makes possible the dissemination of color through the medium in a manner analogous to the dissemination of sound through air or water.
