Nor must it be thought that the Thirteenth Century men and women were satisfied with Church music alone. About the middle of the century part singing came into use in the churches at the less formal ceremonials, and soon spread to secular uses. As the Mystery Plays gave rise to the modern drama, so church music gave birth to the popular music of the time. In England, particularly, about the middle of the century, various glee songs were sung, portions of which have come down to us, and a great movement of folk music was begun. Before the end of the century the interaction of church and secular music had given rise to many of the modes of modern musical {208} development, and the musical movement was as substantially begun as were any of the other great artistic and intellectual movements which this century so marvelously initiated. This subject, of course, is of the kind that needs to be studied in special works if any satisfactory amount of information is to be obtained, but even the passing hint of it which we have been able to give will enable the reader to realize the important place of the Thirteenth Century in the development of modern music. [Illustration] ENTOMBMENT OF BLESSED VIRGIN (NOTRE DAME, PARIS) {209} XIII THREE MOST READ BOOKS OF THE CENTURY. Three books were more read than any others during the Thirteenth Century, that is, of course, apart from Holy Scriptures, which contrary to the usually accepted notion in this matter, were frequently the subject of study and of almost daily contact in one way or another by all classes of people. These three books were, Reynard the Fox, that is the series of stories of the animals in which they are used as a cloak for a satire upon man and his ways, called often the Animal Epic; the Golden Legend, which impressed Longfellow so much that he spent many years making what he hoped might prove for the modern world a bit of the self-revelation that this wonderful old medieval book has been for its own and subsequent generations; and, finally, the Romance of the Rose, probably the most read book during the Thirteenth and Fourteenth and most of the Fifteenth centuries in all the countries of Europe. Its popularity can be well appreciated from the fact that, though Chaucer was much read, there are more than three times as many manuscript copies of The Romance of the Rose in existence as of Chaucer's Canterbury Tales, and it was one of the earliest books to see the light in print.
