Roger Bacon

Roger Bacon known by the scholastic accolade Doctor Mirabilis, was a medieval English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism. In the early modern era, he was regarded as a wizard and famed for the story of his mechanical or necromantic brazen head, he is sometimes credited as one of the earliest European advocates of the modern scientific method. Bacon applied the empirical method of Ibn al-Haytham to observations in texts attributed to Aristotle. Bacon discovered the importance of empirical testing when the results he obtained were different than those that would have been predicted by Aristotle, his linguistic work has been heralded for its early exposition of a universal grammar. However, more recent re-evaluations emphasise that Bacon was a medieval thinker, with much of his "experimental" knowledge obtained from books in the scholastic tradition, he was, however responsible for a revision of the medieval university curriculum, which saw the addition of optics to the traditional quadrivium.

A survey of how Bacon's work was received over the centuries found that it reflected the concerns and controversies that were central to his readers. Bacon's major work, the Opus Majus, was sent to Pope Clement IV in Rome in 1267 upon the pope's request. Although gunpowder was first invented and described in China, Bacon was the first in Europe to record its formula. Roger Bacon was born in Ilchester in Somerset, England, in the early 13th century, although his date of birth is sometimes narrowed down to c. 1210, "1213 or 1214", or "1215". However, modern scholars tend to argue for the date of c. 1220, but there are disagreements on this. The only source for his birth date is a statement from his 1267 Opus Tertium that "forty years have passed since I first learned the Alphabetum"; the latest dates assume this referred to the alphabet itself, but elsewhere in the Opus Tertium it is clear that Bacon uses the term to refer to rudimentary studies, the trivium or quadrivium that formed the medieval curriculum.

His family appears to have been well off. Bacon studied at Oxford. While Robert Grosseteste had left shortly before Bacon's arrival, his work and legacy certainly influenced the young scholar and it is possible Bacon subsequently visited him and William of Sherwood in Lincoln. Bacon became a master at Oxford. There is no evidence he was awarded a doctorate. A caustic cleric named Roger Bacon is recorded speaking before the king at Oxford in 1233. In 1237 or at some point in the following decade, he accepted an invitation to teach at the University of Paris. While there, he lectured on Latin grammar, Aristotelian logic, arithmetic and the mathematical aspects of astronomy and music, his faculty colleagues included Robert Kilwardby, Albertus Magnus, Peter of Spain, the future Pope John XXI. The Cornishman Richard Rufus was a scholarly opponent. In 1247 or soon after, he left his position in Paris; as a private scholar, his whereabouts for the next decade are uncertain but he was in Oxford c. 1248–1251, where he met Adam Marsh, in Paris in 1251.

He seems to have studied most of the known Arabic works on optics. A passage in the Opus Tertium states. By the late 1250s, resentment against the king's preferential treatment of his émigré Poitevin relatives led to a coup and the imposition of the Provisions of Oxford and Westminster, instituting a baronial council and more frequent parliaments. Pope Urban IV absolved the king of his oath in 1261 and, after initial abortive resistance, Simon de Montfort led a force, enlarged due to recent crop failures, that prosecuted the Second Barons' War. Bacon's own family were considered royal partisans: De Montfort's men seized their property and drove several members into exile. In 1256 or 1257, he became a friar in the Franciscan Order in either Paris or Oxford, following the example of scholarly English Franciscans such as Grosseteste and Marsh. After 1260, Bacon's activities were restricted by a statute prohibiting the friars of his order from publishing books or pamphlets without prior approval.

He was kept at constant menial tasks to limit his time for contemplation and came to view his treatment as an enforced absence from scholarly life. By the mid-1260s, he was undertaking a search for patrons who could secure permission and funding for his return to Oxford. For a time, Bacon was able to get around his superiors' interference through his acquaintance with Guy de Foulques, bishop of Narbonne, cardinal of Sabina, the papal legate who negotiated between England's royal and baronial factions. In 1263 or 1264, a message garbled by Bacon's messenger, Raymond of Laon, led Guy to believe that Bacon had completed a summary of the sciences. In fact, he had no money to research, let alone copy, such a work and attempts to secure financing from his family were thwarted by the Second Barons' War. However, in 1265, Guy was summoned to a conclave at Perugia that elected him Pope Clement IV. William Benecor, the courier between Henry III and the pope, now carried the correspondence between Bacon and Clement.

Clement's reply of 22 June 1266 commissioned "writings and remedies for current conditions", instructing Bacon not to
