AMBIX Vol. 23, Part I, March 1976 ROGER BACON'S PLACE IN THE HISTORY OF ALCHEMY by Edmund Brehm A LCHEMY , throughout its history, has shown a dual nature. On the one hand, it has involved the use of chemical substances and so is claimed by the history of science as the precursor of modern chemistry. Yet at the same time, alchemy has, throughout its history, also been associated with the esoteric, spiritual beliefs of Hermeticism and thus is a proper subject for the historian of religious thought. The chemical approach is easily understood. As the distinguished historian of alchemy, the late F. Sherwood Taylor, concluded: "The hopeless pursuit of the practical transmutation of metals was responsible for almost the whole of the development of chemical technique before the seventeenth century, and further led to the discovery of many important materials. This is the commonly recognized contribution of alchemy." Mircea Eliade and others, on the other hand, have emphasized the soteriological function of alchemy as working toward the perfection and liberation of the human soul or spirit, a process symbolized in the perfection of metals into gold and of the human body to a state of optimum health and even immortality. Such an approach is complemented by the psychological studies of C. G. Jung, which correlate alchemical symbolism with the development of the psycho-religious life of the individual. Eliade has conclusively demonstrated the religious nature of alchemy in Eastern cultures, and Jung has discussed the psychological basis of Western alchemy during its later period (the sixteenth and seventeenth centuries). But European alchemy during the Middle Ages, especially from a religious point of view, has received little attention.

ROGER BACON c.1214 - c.1292 English Philosopher Roger Bacon, a Franciscan of Oxford, is regarded as the forerunner of modern experimental science. He made lists of possible inventions 300 years before Leonardo da Vinci. There he described spectacles, flying machines, motorized ships and the process for making gun powder. His writings are a passionate tirade against ignorance. He combined his attack upon the ignorance of his time with suggestions for the increase of knowledge. But the novelty of his ideas led to his imprisonment in 1277.

He received a degree from the University of Paris around 1241. After taking his degree he lectured at Paris on Aristotle 's ideas but at this stage he showed little interest in science. His interest in mathematics and science was acquired at Oxford to which he returned in 1247. He was much influenced by Grosseteste and worked most of his life on languages, mathematics, optics and sciences. In particular he concentrated on studying these topics at Oxford between has arrival in 1247 and 1257. His most important mathematical contribution is the application of geometry to optics. He said:- Mathematics is the door and the key to the sciences. Bacon followed Grosseteste in emphasising the use of lens for magnification to aid natural vision. He carried out some systematic observations with lenses and mirrors. He seems to have planned and interpreted these experiments with a remarkably modern scientific approach. However many experiments are described in his writings which he never carried out in practice. In 1257, perhaps largely due to ill health, Bacon left the University of Oxford and entered the Order of Friars Minor. However he continued his interest in the sciences and this was not appreciated by his superiors. Bacon wrote to Pope Clement IV in 1266, writing what looks remarkably similar to a grant proposal that a mathematician or scientist might make today. His proposal was for an encyclopaedia of all the sciences worked on by a team of collaborators, coordinated by a body in the Church.

R. Green's Short History , chap. III, sect. iv; for a far more authoritative estimate of his work, Rashdall's Universities of Europe in the Miracle Ages , vol. II pp. 522 ff.. Bacon, in Dr Rashdall's words, was "the most astonishing phenomenon of the medieval schools...unlike other medieval thinkers, orthodox or unorthodox, he saw that the study of Greek was the true key to the meaning of Aristotle, and a knowledge of the Bible in the original the true foundation for a fruitful study of theology. All the characteristic ideas of the sixteenth century are held in solution, as it were, in the writings of Roger Bacon, mixed up no doubt with much that is redolent of the age in which he lived; but, of all the anticipations of modern ways of thinking with which his worlds abound, the most remarkable is his plan of educational reform." After twenty years of study and experiments, during which he expended on books and instruments the equivalent of nearly £40,000 modern money [=$200,000 in 1910!], Bacon joined the Franciscan Order, a step which he evidently lived to repent. His superiors forbade him to publish anything, and he would have died unknown but for the intervention of Pope Clement IV, who had heard of him before his elevation to the papacy, and who in 1266 sent a letter bidding him write down his ideas "without delay, and with all possible secrecy, without regard to any contrary precept of your Superiors or any constitution of your Order." In less than two years Bacon wrote three works extending to some 600 folio pages of print-the

document.write(""); BACON, ROGER BACON, ROGER (c. I2i4-c. 1294), English philosopher and man of science, was born near Ilchester in Somerset. His family appears to have been in good circumstances, but in the stormy reign of Henry III. their property was despoiled and several members of the family were driven into exile. Roger completed his studies at Oxford, though not, as current traditions assert, at Merton or at Brasenose, neither of which had then been founded. His abilities were speedily recognized by his contemporaries, and he enjoyed the friendship of such eminent men as Adam de Marisco and Robert Grosseteste, bishop of Lincoln. Very little is known of Bacon's life at Oxford; it is said he took orders in 1233, and this is not improbable. In the following year, or perhaps later, he crossed over to France and studied at the university of Paris, then the centre of intellectual life in Europe. The two great orders, Franciscans and Dominicans, were in the vigour of youth, and had already begun to take the lead in theological discussion. Alexander of Hales was the oracle of the Franciscans, while the rival order rejoiced in Albertus Magnus and Thomas Aquinas. the fame enjoyed by the fluent young doctors roused Bacon’s indignation. In the Opus Minus and Opus Tertium he pours forth a violent tirade against Alexander of Hales, and another professor, not mentioned by name, but spoken of as alive, and blamed even more severely than Alexander. This anonymous writer,f he says, acquired his learning by teaching others, and adopted a dogmatic tone, which has caused him to be received at Paris with applause as the equal of Aristotle, Avicenna, or Averroes.

Roger Bacon - Tract on the Tincture and Oil of Antimony On the true and right Preparation of Stibium / to heal human weaknesses and illnesses therewith, and to improve the imperfect metals. Translated by Kjell Hellesoe 1985. From Friedrich Roth-Scholtz, Deutsches theatrum chemicum , Nürnberg: Adam Jonathan Felsecker, 1731. Preface Dear reader, at the end of his Tract on Vitriol, Roger Bacon mentions that because of the multiplication of the Tincture that is made from Vitriol, the lover of Art should acquaint himself with the Tract De Oleo Stibii. Therefore I considered that it would be good and useful that the Tract De Oleo Stibii follows next. And if one thoroughly ponders and compares these tinctures with one another, then I have no doubt that one will not finish without exceptional profit. Yet, every lover of Art, should mind always to keep one eye on Nature and the other on Art and manual labour. For, when these two do not stand together, then it is a lame work, as when someone thinks he can walk a long path on one leg only, which is easily seen to be impossible, Vale.

There are two ways of acquiring knowledge, one through reason, the other by experiment. Argument reaches a conclusion and compels us to admit it, but it neither makes us certain nor so annihilates doubt that the mind rests calm in the intuition of truth, unless it finds this certitude by way of experience. Thus many have arguments toward attainable facts, but because they have not experienced them, they overlook them and neither avoid a harmful nor follow a beneficial course. Even if a man that has never seen fire, proves by good reasoning that fire burns, and devours and destroys things, nevertheless the mind of one hearing his arguments would never be convinced, nor would he avoid fire until he puts his hand or some combustible thing into it in order to prove by experiment what the argument taught. But after the fact of combustion is experienced, the mind is satisfied and lies calm in the certainty of truth. Hence argument is not enough, but experience is. Source: From: Oliver J. Thatcher, ed.

34. Sound Body Jazz Orchestra A collaboration of the roger bacon High School Band Alumni. http://www.sbjazzorchestra.com/

Dedicated to bringing the joy of Big Band Music to people of all ages Formed in 1992 as a collaboration of Cincinnati, Ohio's, Roger Bacon High School Band Alumni, Sound Body has received tremendous response to its eclectic combination of classic big band swing with contemporary jazz and fusion. The band's name, adapted from the high school's Latin motto, "Mens Sana en Corpore Sano" (A Sound Mind in a Sound Body), is quite appropriate, given the powerhouse ensemble work that is the trademark of the 18-piece group. The jazz orchestra is an original American art form that combines the sheer joy and freedom of jazz rhythms with a rich and powerful orchestral sound. Following in the tradition of the famous jazz orchestras of the 1930s and 40s (commonly known as "big bands"), Sound Body plays an eclectic mix of styles - from classic swing to hard-driving Latin, to lush ballads. But what makes this ensemble unique is the addition of contemporary jazz and fusion tunes from the 1970s to today. The common thread of this broad repertoire: it's all great dance music! 4125 Wenbrook Drive Cincinnati, Ohio 45241

Branch of Science Scholars Nationality English Bacon, Roger (1220-1292) English scholar who, at one point, studied under Grosseteste at Oxford. He attempted to write a universal encyclopedia of knowledge. He is one of the first people (in the West) known to have mentioned gunpowder. Bacon appealed to Pope Clement to allow more experimentation in the educational system. He tried to construct a rainbow using glass beads in order to study it. This marked one of the earliest attempts to reproduce a natural phenomenon in the lab for closer scrutiny. Grosseteste References Clegg, B. The First Scientist: The Visionary Genius of Roger Bacon.
