However, the most interesting musical instrument in Strassburg is the organ of the cathedral made by Andreas Silbermann. Notwithstanding the care exercised by the beleaguerers to prevent damage to the cathedral, a shell found its way right through the centre of the organ, and must have greatly injured this work of art. Andreas Silbermann was no mere handicraftman, but an artist like Amati or Stradivari. He was born in Saxony, settled in Strassburg in the year 1701, and built the organ of the cathedral in 1715. His brother, Gottfried Silbermann of Saxony, was likewise a distinguished maker, not only of organs, but also of clavichords, and an improver of the pianoforte soon after its invention, in the beginning of the eighteenth century. Almost all the organs built during the eighteenth century for the churches of Strassburg are by Andreas Silbermann and his sons. Among the latter, Johann Andreas is noteworthy on account of his antiquarian pursuits. He wrote, besides other works, a 'History of the Town of Strassburg,' which was published in folio, with engravings, in the year 1775. His collection of sketches drawn by himself of the most remarkable scenery, and of old castles and other interesting buildings of Alsace, and likewise his collection of the old coins of Strassburg, were preserved in the town library, and are, it is to be feared, now lost. As even the catalogue of the library has, it is said, been burnt, it may be worth while to notice some of the losses. With the irreparable ones must be recorded a copy of the first hymn book of the Protestant Church, of which no other copy is known to be extant. It was published at Erfurt in the year 1524, and contains twenty-five songs, eighteen of which are by Luther. Its title is _Enchiridion, oder eyn Handbuchlein eynem yetzlichen Christen fast nutzlich bey sich zu haben, zur stetter vbung vnd trachtung geystlicher gesenge und Psalmen, Rechtschaffen vnd Kunstlich vertheutscht_. ("Enchiridion, or a little Hand-book, very useful for a Christian at the present time to have by him for the constant practice and contemplation of spiritual songs and psalms, judiciously and carefully put into German.") The musical notation is given with the words. It is believed that Luther gave the manuscript of his own songs, and most likely also of the other songs, and of the musical notation, into the hands of the publisher;--that, in fact, the "Enchiridion" emanated directly from Luther. A _fac-simile_ of this book was published in Erfurt in the year 1848. Only three chorales are known with certainty to be of Luther's composition.
