Neckam, despite the fact that according to his editor, Thomas Wright, he “not infrequently displays a taste for experimental science,”[22] was, after all, more of a moralizing compiler than anything else. But greater men than Neckam, men who were interested in learning and science for their own sake, men who knew more and wrote more, still cherished beliefs of the same sort. There was Michael Scot in the early years of the thirteenth century, the wonder of the cultured court of Frederick II, perhaps that monarch’s tutor, the “Supreme Master” of Paris, the man who helped much to make the treasures of learning amassed by the Arabs in Spain the common property of Latin Christendom, the introducer to Western Europe of a Latin version of Averroes and of an enlarged Aristotle.[23] Scot composed a primer of astrology for young scholars. His writings on alchemy show that he experimented in it not a little. His _Physionomia_ accepts the doctrine of signatures, tells us that these signs on the outward body of the soul’s inner state are often discovered through dreams, and contains a chapter giving an extended description of the rules of augury—an art on which the author, though a Christian, apparently bestowed his sanction. Prophetic verses foretelling the fate of several Italian cities have come down to us under his name. A poem of Henri d’Avranches, written in 1235–6, recalls to mind the fact that certain prophecies concerning the emperor had been made by the then deceased Michael Scot, whom the poet proceeds to call a scrutinizer of the stars, an augur, a soothsayer, a _veridicus vates_, and a second Apollo.[24] A most interesting recipe for invoking demons to instruct one in liberal arts is attributed to Michael Scot in a manuscript collection of _Occulta_ in the Laurentian library.[25] Later in the same century stands forth the famous figure of Roger Bacon, the stout defender of mathematics and physics against scholasticism. Some have ascribed to him numerous important innovations in the realm of natural science and of the mechanical arts, and have regarded his promulgation of the experimental method, guided by the mathematical method, as the first herald note of that modern science which was not destined really to appear for yet several centuries. Yet he held that the alchemist, if given sufficient time and money, could discover a way not only to meet the state’s expenses by converting baser metals into gold, but also to prolong human existence beyond that limit to which it can be drawn out by nature.[26] Indeed these objects constituted two of the three examples he gave of the great advantages to be gained from the pursuit of that experimental science which was to disprove and blot out all magical nonsense.[27]
