 A second task for experimental science is the discovery by ‘experience’ alone of instruments (e.g., the armillary sphere), new medical cures, chemical discovery, and military technologies. An important item here is the discovery of magnetism. It would seem that Bacon is reporting on the actual experimental work of Magister Petrus Peregrinus (fl. 1260–77), author of De magnete, who is lauded in the Opus tertium as the only worthwhile “experimentalist” at Paris (see Silvia Nagel 2012). Bacon has been lauded down the centuries for his medical learning, but recent scholarship has limited the number of works attributed to Bacon. Still, it is important to note that he did draw on medical practice to set out rules and procedures. Here, the recent research of Agostino Paravicini-Bagliani (1991, 2000) shows that Bacon shared these interests with other outstanding scholars such as Peter of Spain (Pope John XXI). The very concept of the ‘prolongation of life’ so forcefully proposed by Bacon in his later works found very receptive readers at the Papal Curia in Viterbo. The Papal Curia had by 1266 become a center for medical and scientific study. The third task is that of the prognostication of the future on the basis of astronomical/astrological knowledge. This section, depending on Pseudo-Ptolemy, Centiloquiium and Abu Ma’shar notes that this revelatory divination is earier and more available than the more complex regular astronomy that requires constant observation and the skillful uses of Tables and Instruments. These are not always readily available.
