messenger, Raymond of Laon, led Guy to believe that Bacon had already 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 . William Benecor, who had previously been 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 violate any standing "prohibitions" of his order but to carry out his task in utmost secrecy. While faculties of the time were largely limited to addressing disputes on the known texts of Aristotle, Clement's patronage permitted Bacon to engage in a wide-ranging consideration of the state of knowledge in his era. In 1267 or '68, Bacon sent the Pope his , which presented his views on how to incorporate Aristotelian logic and science into a new theology, supporting Grosseteste's text-based approach against the "sentence method" then fashionable. Bacon also sent his , , , an optical lens, and possibly other works on alchemy and astrology. The entire process has been called "one of the most remarkable single efforts of literary productivity", with Bacon composing referenced works of around a million words in about a year. Pope Clement died in 1268 and Bacon lost his protector. The Condemnations of 1277 banned the teaching of certain philosophical doctrines, including deterministic astrology. Some time within the next two years, Bacon was apparently imprisoned or placed under house arrest. This was traditionally ascribed to Franciscan Minister General Jerome of Ascoli, probably acting on behalf of the many clergy, monks, and educators attacked by Bacon's 1271 . Modern scholarship, however, notes that the first reference to Bacon's "imprisonment" dates from eighty years after his death on the charge of unspecified "suspected novelties" and finds it less than credible. Contemporary scholars who do accept Bacon's imprisonment typically associate it with Bacon's "attraction to contemporary prophesies", his sympathies for "the radical 'poverty' wing of the Franciscans", interest in certain astrological doctrines, or generally combative personality rather than from "any scientific novelties which he may have proposed". Sometime after 1278, Bacon returned to the Franciscan House at Oxford, where he continued his studies and is presumed to
