Dr. Paul Zachias, who was a distinguished Roman physician of the time, said that he had long known Father Kircher as an eminent writer on other subjects, but that after reading his book on the pest he must consider him also distinguished in medical writing. He says: "While he has set his hand at other's harvests, he has done it with so much wisdom and prudence as to win the admiration of the harvesters already in the field." He adds that there can be no doubt that it would be a source of profit for medical men to read this little book and that it will undoubtedly prove beneficial to future generations. Testimony of another kind to the value of Father Kircher's book is to be found in the fact [{117}] that within a half-year after its publication in Latin it appeared in several other languages. It is too much the custom of these modern times to consider that scientific progress in the centuries before our own and its immediate predecessor was likely to attract little attention for many years, and was especially slow to make its way into foreign countries. Anything, however, of real importance in science took but a very short time to travel from one country to another in Europe in the seventeenth century, and the fact that scientific men generally used Latin as a common language made the spread of discoveries and speculations much easier even than at the present time. Our increased means of communication have really only served to allow sensational announcements of a progress in science--which is usually no progress at all--to be spread quite as effectually in modern times as were real advances in the older days.
There is no good account of Father Kircher's life available in English, and it has seemed only proper that the more important at least of the details of the life of the man who thus anticipated the beginnings of modern bacteriology and of the relations of micro-organisms to disease, should not be left in obscurity. His life history is all the more interesting and important because it illustrates the interest of the churchmen of the time, and especially of the Roman ecclesiastical authorities, in all forms of science; for Father Kircher is undoubtedly one of the greatest scholars of [{118}] history and one of the scientific geniuses in whose works can be found, as the result of some wonderful principles of intuition incomprehensible to the slower intellectual operations of ordinary men, anticipations of many of the discoveries of the after-time. There is scarcely a modern science he did not touch upon, and nothing that he touched did he fail to illuminate. His magnificent collections in the museum of the Roman College demonstrate very well his extremely wide interests in all scientific matters.
The history of Father Kircher's career furnishes perhaps the best possible refutation of the oft-repeated slander that Jesuit education was narrow and was so founded upon and rooted in authority that original research and investigation, in scientific matters particularly, were impossible, and that it utterly failed to encourage new discoveries of any kind. As a matter of fact, Kircher was not only not hampered in his work by his superiors or by the ecclesiastical authorities, but the respect in which he was held at Rome enabled him to use the influence of the Church and of great churchmen all over the world, with the best possible effect, for the assembling at the Roman College of objects of the most various kinds, illustrating especially the modern sciences of archeology, ethnology, and paleontology, besides Egyptian and Assyrian history.
Athanasius Kircher was born 2 May, 1602, at Geisa, near Fulda, in South Germany. He was educated at the Jesuit College of Fulda, and at [{119}] the early age of sixteen, having completed his college course, entered the Jesuit novitiate at Mainz. After his novitiate he continued his philosophical and classical studies at Paderborn and completed his years of scholastic teaching in various cities of South Germany--Munster, Cologne, and Coblenz--finally finishing his education by theological studies at Cologne and Mainz.
Toward the end of the third decade of the seventeenth century he became Professor of Philosophy and Mathematics at Würzburg. Here his interest in Oriental languages began, and he established a special course in this subject at the University of Würzburg. During the Thirty Years' War, however, the invasion of Germany very seriously disturbed university work, and finally in 1631 Father Kircher was sent by his superiors to Avignon in South France, where he continued his teaching some four years, attracting no little attention by his wide interest in many sciences and by various scientific works that showed him to be a man of very broad genius.
In 1635, through the influence of Cardinal Barberini, he was summoned to Rome, where he became Professor of Mathematics and Oriental Languages in the famous Roman College of the Jesuits, which was considered at that time one of the greatest educational institutions in the world. His interest in science, however, was not lessened by teaching duties that would apparently have demanded all his time; and, as we shall see, he continued to issue books on the most diverse [{120}] scientific subjects, most of them illustrated by absolutely new experimental observations and all of them attracting widespread attention.
Father Kircher began his career as a writer on science at the early age of twenty-seven, when he issued his first work on magnetism. The title of this volume, "Ars Magnesia tum Theorematice tum Problematice Proposita," shows that the subject was not treated entirely from a speculative standpoint. Indeed, in the preface he states that he hopes that the principal value of the book will be found in the fact that the knowledge of magnetism is presented by a new method, with special demonstrations, and that the conclusions are confirmed by various practical uses and long-continued experience with magnets of various kinds.
Although it may be a source of great surprise, Father Kircher's genius was essentially experimental. He has been spoken of not infrequently as a man who collected the scientific information of his time in such a way as to display, as says the Encyclopedia Britannica, "a wide and varied learning, but that he was a man singularly devoid of judgment and critical discernment." He was in some respects the direct opposite of the opinion thus expressed, since his learning was always of a practical character, and there are very few subjects in this writing which he has not himself illustrated by means of new and ingenious experiments.
Perhaps the best possible proof of this is to be [{121}] found in the fact that his second scientific work was on the construction of sun-dials, and that one of the discoveries he himself considered most valuable was the invention of a calculating machine, as well as of a complicated arrangement for illustrating the positions of the stars in the heavens. He constructed, moreover, a large burning-glass in order to demonstrate the possibility of the story told of Archimedes, that he had succeeded in burning the enemy's ships in the harbor at Syracuse by means of a large lens.
But Father Kircher's surest claim to being a practical genius is to be found in his invention of the magic lantern. It was another Jesuit, Aquilonius, in his work on optics, issued in 1613, who had first sought to explain how the two pictures presented to the two eyes are fused into one, and it was in a practical demonstration of this by means of lenses that Kircher hit upon the invention of the projecting stereoscope.
