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 raisonne_ of such works. Very probably the first who should be mentioned in the list is Boethius, 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 Boethius--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 Boethius 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 Provencal popular poetry, and also in early Italian verse.
