The idea of collecting general information from many sources, of bringing it together into an easily available form, so as to save others labor, of writing it out in compendious fashion, so that it could readily pass from hand to hand, is likely to be considered typically modern. As a matter of fact, the Middle Ages furnish us with many examples of the popularization of science, of the writing of compendia of various kinds, of the gathering of information to save others the trouble, and, above all, of the making of what, in the modern time, we would call encyclopedias. Handbooks of various kinds were issued, manuals for students and specialists, and many men of broad scholarship in their time devoted themselves to the task of making the acquisition of knowledge easy for others. This was true not only for history and philosophy and literature, but also for science. It is not hard to find in each century of the Middle Ages some distinguished writer who devoted himself to this purpose, and for the sake of the light that it throws on these scholars, and the desire for information that must have existed very commonly since they were tempted to do the work, it seems worth while to mention here their names, and those of the books they wrote, with something of their significance, though the space will not permit us to give here much more than a brief catalogue raisonnÉ of such works.

Very probably the first who should be mentioned in the list is BoËthius, who flourished in the early part of the sixth century. He owed much of his education to his adoptive father, afterwards his father-in-law, Symmachus, who, with Festus, represented scholarship at the court of the Gothic King, Theodoric of Verona. These three—Festus, Symmachus, and BoËthius—brought such a reputation for knowledge to the court that they are responsible for many of the wonderful legends of Dietrich of Bern, as Theodoric came to be called in the poems of the medieval German poets. The three distinguished and devoted scholars did much to save Greek culture at a time when its extinction was threatened, and BoËthius particularly left a series of writings that are truly encyclopedic in character. There are five books on music, two on arithmetic, one on geometry, translations of Aristotle's treatises on logic, with commentaries; of Porphyry's "Isagoge," with commentaries, and a commentary on Cicero's "Topica." Besides, he wrote several treatises in logic and rhetoric himself, one on the use of the syllogism, and one on topics, and in addition a series of theological works. His great "Consolations of Philosophy" was probably the most read book in the early Middle Ages. It was translated into Anglo-Saxon by King Alfred, into old German by Notker Teutonicus, the German monk of St. Gall, and its influence may be traced in Beowulf, in Chaucer, in High German poetry, in Anglo-Norman and ProvenÇal popular poetry, and also in early Italian verse. Above all, the "Divine Comedy" has many references to it, while the "Convito" would seem to show that it was probably the book that most influenced Dante. Though it is impossible to confirm by documentary evidence the generally accepted idea that BoËthius died a martyr for Christianity, the tradition can be traced so far back, and it has been so generally accepted that this seems surely to have been the case. The fact is interesting, as showing the attitude of scholars towards the Church and of the Church towards scholarship thus early.

The next great name in the tradition should probably be that of Cassiodorus, the Roman writer and statesman, prime minister of Theodoric, who, after a busy political life, retired to his estate at Vivarium, and, in imitation of St. Benedict, who had recently established a monastery at Monte Cassino, founded a monastery there. He is said to have lived to the age of ninety-three. His retirement favored this long life, for, after the death of Theodoric, troublous times came, and civil war, and only his monastic privileges saved him from the storm and stress of the times. He had been interested in literature and the collection of information of many kinds before his retirement, and it is not unlikely that his recognition of the fact that the monastic life offered opportunities for the pursuit of this, under favorable circumstances, led him to take it up.

While still a statesman he wrote a series of works relating to history and politics and public affairs generally. These consisted mainly of chronicles and panegyrics, and twelve books of miscellanies called VariÆ. After his retirement to the monastery, a period of ardent devotion to writing begins, and a great number of books were issued. He evidently gathered round him a number of men whom he inspired with his spirit, or, perhaps, selected, because he found that, while they had a taste for a quiet, peaceful spiritual life, they were also devoted to the accumulation and diffusion of knowledge. A series of commentaries on portions of the Scriptures was written, the Jewish antiquities of Josephus translated, and the ecclesiastical histories of Theodoric, Sozomen, and Socrates made available in Latin. Cassiodorus himself is said to have made a compendium of these, called the "Historia Tripartita," which was much used as a manual of history during succeeding centuries. Then there were treatises on grammar, on orthography, and a series of works on mathematics. In all of his writings Cassiodorus shows a special fondness for the symbolism of numbers.

There is a well-grounded tradition that he insisted on the study of the Greek classics of medical literature, especially Hippocrates and Galen, and awakened the interest of the monks in the necessity for making copies of these fathers of medicine. The tradition that he established at Vivarium is also found to have existed at Monte Cassino among the Benedictines, and, doubtless, to this is to be attributed the foundation of the medical school of Salerno, where Benedictine influence was so strong. It is probable, therefore, that to Cassiodorus must be attributed the preservation in as perfect a state as we have them of the old Greek medical writers.

His main idea was, of course, the study of Scriptures, but with just as many helps as possible. He thought that commentators, and historians, not alone Christian, but also Hebrew and Pagan, should be studied to illustrate it, and then the commentaries of the Latin fathers, so that a thoroughly rounded knowledge of it should be obtained. He thus began an "Encyclopedia Biblica," and set a host of workers at its accomplishment.

Every country in Europe shared this movement for the diffusion of information during the early Middle Ages, and the works of men from each of these countries in succeeding centuries has come down to us, preserved in spite of all the vicissitudes to which they were so liable during the centuries before the invention of printing and the easy multiplication of books. To many people it will seem surprising to learn that the next evidence of deep broad interest in knowledge is to be found in the next century in the distant west of Europe, in the Spanish Peninsula. It is a long step from the semi-barbaric splendor of the Gothic court at Verona, to the bishop's palace in Seville in Andalusia. The two cities are separated by what is no inconsiderable distance in our day. In the seventh century they must have seemed almost at the other end of the world from each other. Those who recall what we have insisted on in several portions of the body of this work with regard to the high place Spanish genius won for itself in the Roman Empire, and how much of culture among the Spaniards of that time the occurrence of so many important writers of that nationality must imply, will not be surprised at the distinguished work of a great Christian Spanish writer of the seventh century.

Indeed, it would be only what might be expected for evidences of early awakening of the broadest culture to be found in Spain. The important name in the popularization of science in the seventh century is St. Isidore of Seville. He made a compendium of all the scattered scientific traditions and information of his time with regard to natural phenomena in a sort of encyclopedia of science. This consisted of twenty books—chapters we would call them now—treating almost de omni re scibili et quibusdam aliis (everything knowable and a few other things besides). It is possible that the work may have been written by a number of collaborators under the patronage of the bishop, though there is no sure indication of this to be found either in the volume itself or even contemporary history. All the ordinary scientific subjects are treated. Astronomy, geography, mineralogy, botany, and even man and the animals have each a special chapter. Pouchet, in his "History of the Natural Sciences During the Middle Ages," calls attention to the fact that, in grouping the animals for collective treatment in the different chapters, sometimes the most heterogeneous creatures are brought under a common heading. Among the fishes, for instance, are classed all living things that are found in water. The whale and the dolphin, as well as sponges, and oysters, and crocodiles, and sea serpents, and lobsters, and hippopotamuses, all find a place together, because of the common watery habitation. The early Spanish Churchman would seem to have had an enthusiastic zeal for complete classification that would surely have made him a strenuous modern zoÖlogist.

The next link in the tradition of encyclopedic work is the Venerable Bede, whose character was more fully honored by the decree on November 13, 1899, by Pope Leo XIII declaring him a Doctor of the Church. Bede was the fruit of that ardent scholarship which had risen in England as a consequence of the introduction of Christianity. It had been fostered by the coming of scholar saints from Ireland, but was, unfortunately, disturbed by the incursions of the Danes. While Bede is known for his greatest work, the "Ecclesiastical History of the English People," which gives an account of Christianity in England from its beginning until his own day, he wrote many other works. His history is the foundation of all our knowledge of early British history, secular as well as religious, and has been praised by historical writers of all ages, who turned to it for help with confidence. He wrote a number of other historical works. Besides, he wrote books on grammar, orthography, the metrical art, on rhetoric, on the nature of things, the seasons, and on the calculation of the seasons. These latter books are distinctly scientific. His contributions to Gregorian Music are now of great value.

After this, Alcuin and the monks, summoned by Charlemagne, take up the tradition of gathering and diffusing information, and the great monasteries of Tours, Fulda, and St. Gall carry it on. Besides these, in the ninth century Monte Cassino comes into prominence as an institution where much was done of what we would now call encyclopedic work. After his retirement from Salerno Constantine Africanus made his translations and commentaries on Arabian medicine, constituting what was really a medical encyclopedia of information not readily available at that time.

After this, of course, the tradition is taken up by the universities, and it is only when, with the thirteenth century, there came the complete development of the university spirit, that encyclopedias reached their modern expression. Three great encyclopedists, Vincent of Beauvais, Thomas of Cantimprato, and BartholomÆus Anglicus, are the most famous. Vincent consulted all the authors sacred and profane that he could lay hold on, and the number was, indeed, prodigious. I have given some account of him in "The Thirteenth Greatest of Centuries" (Catholic Summer School Press, New York, third edition, 1910).

It would be very easy to conclude that these encyclopedias, written by clergymen for the general information of the educated people of the times, contain very little that is scientifically valuable, and probably nothing of serious medical significance. Any such thought is, however, due entirely to unfamiliarity with the contents of these works. They undoubtedly contain absurdities, they are often full of misinformation, they repeat stories on dubious authority, and sometimes on hearsay, but usually the source of their information is stated, and especially where it is dubious, as if they did not care to state marvels without due support. Books of popular information, however, have always had many queer things,—queer, that is, to subsequent generations,—and it is rather amusing to pick up an encyclopedia of a century ago, much less a millennium ago, and see how many absurd things were accepted as true. The first edition of the "Encyclopedia Britannica," issued one hundred and fifty years ago, furnishes an easily available source of the absurdities our more recent forefathers accepted. The men of the Middle Ages, however, were much better observers as a rule, and used much more critical judgment, according to their lights, than we have given them credit for. Often the information that they have to convey is not only valuable, but well digested, thoroughly practical, and sometimes a marvellous anticipation of some of our most modern thoughts. There is one of these encyclopedias which, because it was written in my favorite thirteenth century, I have read with some care. It is simply a development of the work of preceding clerical encyclopedists, and often refers to them. Because it contains some typical examples of the better sorts of information in these works, I have thought it worth while to quote two passages from it. The author is BartholomÆus Anglicus, and the quaint English in which it is couched is quoted from "Medical Lore" (London, 1893). The book is all the more interesting because in a dear old English version, issued about 1540, the spellings of which are among the great curiosities of English orthography, it was often read and consulted by Shakespeare, who evidently quotes from it frequently, for not a little of the quaint scientific lore that he uses for his figures can be traced to expressions used in this book.

The first of the paragraphs that deserves to be quoted, discusses madness, or, as we would call it, lunacy, and sums up the causes, the symptoms, and the treatment quite as well as that has ever been done in the same amount of space:

Madness cometh sometime of passions of the soul, as of business and of great thoughts, of sorrow and of too great study, and of dread: sometime of the biting of a wood hound, or some other venomous beast; sometime of melancholy meats, and sometime of drink of strong wine. And as the causes be diverse, the tokens and signs be diverse. For some cry and leap and hurt and wound themselves and other men, and darken and hide themselves in privy and secret places. The medicine of them is, that they be bound, that they hurt not themselves and other men. And namely, such shall be refreshed, and comforted, and withdrawn from cause and matter of dread and busy thoughts. And they must be gladded with instruments of music, and some deal be occupied.'
