Among the historic groups of hymns that have appeared since Clement of Alexandria and Ephraëm the Syrian set in motion the tide of Christian song, the Lutheran hymnody has the greatest interest to the student of church history. In sheer literary excellence it is undoubtedly surpassed by the Latin hymns of the mediaeval Church and the English-American group; in musical merit it no more than equals these; but in historic importance the Lutheran song takes the foremost place. The Latin and the English hymns belong only to the history of poetry and of inward spiritual experience; the Lutheran have a place in the annals of politics and doctrinal strifes as well. German Protestant hymnody dates from Martin Luther; his lyrics were the models of the hymns of the reformed Church in Germany for a century or more. The principle that lay at the basis of his movement gave them their characteristic tone; they were among the most efficient agencies in carrying this principle to the mind of the common people, and they also contributed powerfully to the enthusiasm which enabled the new faith to maintain itself in the conflicts by which it was tested. The melodies to which the hymns of Luther and his followers were set became the foundation of a musical style which is the one school worthy to be placed beside the Italian Catholic music of the sixteenth century. This hymnody and its music afforded the first adequate outlet for the poetic and musical genius of the German people, and established the pregnant democratic traditions of German art as against the aristocratic traditions of Italy and France. As we cannot overestimate the spiritual and intellectual force which entered the European arena with Luther and his disciples, so we must also recognize the analogous elements which asserted themselves at the same moment and under the same inspiration in the field of art expression, and gave to this movement a language which helps us in a peculiar way to understand its real import. The first questions which present themselves in tracing the historic connections of the early Lutheran hymnody are: What was its origin? Had it models, and if so, what and where were they? In giving a store of congregational songs to the German people was Luther original, or only an imitator? In this department of his work does he deserve the honor which Protestants have awarded him?
