Light Refracted by Water Glass, 13th Century


A 13th-century diagram showing light being refracted by a spherical glass container full of water. From a scientific study of optics by either Robert Grosseteste or his disciple Roger Bacon. Robert Grosseteste (c. 1175 - 1253) was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He has been called the "founder of the tradition of scientific thought in medieval Oxford." He is best known for a host of scientific treatises including: an introductory text on astronomy, a treatise on the metaphysics of light, a work on tides and tidal movements, a study of the rainbow, and a treatise on mathematical reasoning in the natural sciences. Roger Bacon (1214-1294) was an English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empirical methods. He is sometimes credited as one of the earliest European advocates of the modern scientific method inspired by Aristotle and later Arabic scholars such as the Muslim scientist Alhazen. He studied at Oxford and may have been a disciple of Grosseteste.
