 Parts four, five, and six of the Opus maius present the main themes of Bacon’s contribution to scientific education. It is important to see his main contribution to science as one who advocated “scientific education” in an Arts Faculty that was predominantly dedicated to linguistic arts. Bacon had a very wide reading knowledge of most of the newly translated work from Greek, Jewish, and Islamic Philosophy and Science. His major claim to fame in science is that he is the first Latin Western thinker to comprehend and write on most of the ancient sources of optics. In brief, he initiates the tradition of Optics/Perspectiva in the Latin world. This tradition would be formulated as teaching text by his contemporaries Pecham and Witelo. Bacon’s optics was also read and commented on in 14th century Italy by, especially by Lorenzo Ghiberti. It was known to and used by Leonardo Da Vinci. And it was part of the tradition of learning that led to Kepler and Descartes. In his Perspectiva and De scientia experimentali, Bacon outlines a sketch for a scientific method, one that takes optics as the model for an experimental science. In fact, he succeeded in his endeavor in that Perspectiva was added to the four traditional university subjects of the quadrivium: arithmetic, geometry, astronomy, music.
