2 The popular impression that the hymn "Ein' feste Burg" was produced in these circumstances is due, doubtless, to a parallel in the third stanza, to the famous saying imputed to Luther on the eve of the Diet of Worms: "I'll go, be there as many devils in the city as there be tiles on the roofs." The time of its composition was in the year 1529, just before the Diet of Augsburg. If not written in his temporary refuge, the noble "Burg" or "Festung" of Coburg, it must often have been sung there by him; and it was sung, says Merle d'Aubigne, "during the Diet, not only at Augsburg, but in all the churches of Saxony." 3 This much-quoted phrase is from Richter. It is reported as an expression of Melanchthon, looking on Luther's picture, _" Fulmina erant singula verba tua."_ 4 Merle d'Aubigne, History of the Reformation, Vol. III. 5 This interesting and characteristic document was printed first in the _Syntagma Musicum_ of Michael Praetorius, many of whose harmonies are to be found in this volume. It has been repeatedly copied since. I take it from Rambach, "Ueber D. Martin Luthers Verdienst um den Kirchengesang, oder Darstellung desjenigen was er als Liturg, als Liederdichter und Tonsetzer zur Verbesserung des oeffentlichen Gottesdienstes geleistet hat. Hamburg, 1813." 6 Quoted in Rambach, p. 215. 7 In more than one of his cantatas, especially that for the Reformationsfest. Luther's First Preface. To the _"Geystliche Gsangbuechlin, Erstlich zu Wittenberg, und volgend durch Peter schoeffern getruckt, im jar_ m. d. xxv. Autore Ioanne Walthero." That it is good, and pleasing to God, for us to sing spiritual songs is, I think, a truth whereof no Christian can be ignorant; since not only the example of the prophets and kings of the Old Testament (who praised God with singing and music, poesy and all kind of stringed instruments) but also the like practice of all Christendom from the beginning, especially in respect to psalms, is well known to every one: yea, St. Paul doth also appoint the same (I Cor. xiv.) and command the Colossians, in the third chapter, to sing spiritual songs and psalms from the heart unto the Lord, that thereby the word of God and Christian doctrine be in every way furthered and practiced. Accordingly, to make a good beginning and to encourage others who can do it better, I have myself, with some others, put together a few hymns, in order to bring into full play the blessed Gospel, which by God's grace hath again risen: that we may boast, as Moses doth in his song (Exodus xv.) that Christ is become our praise and our song, and that, whether we sing or speak, we may not know anything save Christ our Saviour, as St. Paul saith (I Cor. ii).
