An excellent example of this is to be noted in Dr. Julius Pagel, who, in his chapter on Medicine in the Middle Ages, in Puschmann's Handbook of the History of Medicine, says: "There were three writers whose works were even more popular than those of Albertus Magnus. These three were: Bartholomew the Englishman, Thomas of Cantimprato, and Vincent of Beauvais, the last of whom must be considered as one of the most important contributors to the generalization of scientific knowledge, not alone in the thirteenth, but in the immediately succeeding centuries. His most important work was really an encyclopedia of the knowledge of his time. It was called the Greater Triple Mirror, and there is no doubt that it reflected very thoroughly the knowledge of his period. He had the true scientific spirit, and constantly cites the authorities from whom his information was derived. He cites hundreds of authors, and there is scarcely a subject that he does not {337} touch on. One book of his work is concerned with human anatomy, and the concluding portion of it is an abbreviation of history carried down to the year 1250." It might be considered that such a compend of information would be very dry-as-dust reading and that it would be fragmentary in character and little likely to be attractive except to a serious student. Dr. Pagel's opinion does not agree with this _a priori_ impression. He says with regard to Vincent's work: "The language is clear, readily intelligible, and the information is conveyed usually in an excellent, simple style. Through the introduction of interesting similes the contents do not lack a certain taking quality, so that the reading of the work easily becomes absorbing." This is, I suppose, almost the last thing that might be expected of a scientific teacher in the thirteenth century, because, after all, Vincent of Beauvais must be considered as one of the schoolmen, and they are supposed to be eminently arid, but evidently, since we must trust this testimony of a discerning modern German physician, only by those who have not taken the trouble to read them. Vincent of Beauvais was not the only one to occupy himself with work of an encyclopedic character during the thirteenth century. At least two other clergymen gave themselves up to the life-long work of collecting details of information so as to make them available for ready reference in their own times and for succeeding generations. The very fact that three men should have taken up such a task, shows that there must have been a loud call for this sort of writing, and that there must have been a veritable thirst for information among the educated classes of the time. Such books, as we have said, are not created without a demand for them, though {338} they undoubtedly serve in turn to awaken a greater thirst for the information which they purvey. The other two encyclopedists of the time are Thomas Cantipratano and Bartholomaeus Anglicus, the Englishman.
