 The second and better known interpretation of Roger Bacon as a scientist is found in nineteenth and twentieth century writers on the history of science and has a solid basis in Bacon’s own work, e.g., the edition of the Opus tertium by J.S. Brewer [OQHI]. Bacon’s Perspectiva (1267) [PRSP, 1996] presents a model for an experimental science that ushered in a new addition to the traditional Quadrivium (arithmetic, geometry, astronomy, music) in the new universities of the Latin West, namely, the study of optics. The university teaching text, “The Common Teaching on Perspectiva,” was written by Bacon’s Parisian colleague,John Pecham. We have critical editions now for the major scientific works of Bacon. SISMEL at Florence, Italy now houses a Roger Bacon research center. It has plans for future critical editions. A new international society for the study of Roger Bacon, The Roger Bacon Research Society has recently been established.
