Roger Bacon

Roger Bacon was a thirteenth-century English Franciscan philosopher whose work ranged across optics, language, mathematics, theology and the study of nature. In the Opus Majus and related writings prepared for Pope Clement IV, he argued for linguistic training, practical observation and the reform of learning. Later legend transformed him into a magician and inventor far beyond what the evidence supports.

James Blish’s Doctor Mirabilis makes Bacon the centre of an intellectually demanding historical novel about knowledge, religious authority and the cost of pursuing a universal science. He also appears in older fiction and drama as the legendary Friar Bacon. Modern portrayals are strongest when they distinguish his genuine experimental interests from anachronistic claims that he was a modern scientist born centuries too early.
