Considerable interest attaches, or should attach, to Martin Luther's tract entitled “Die Sieben puszpsalm mit deutscher auszlegung nach dem schrifftlichen synne tzu Christi vnd gottis gnaden, neben seyns selben ware erkentniss grundlich gerichtet.” Appearing in the early spring of 1517, approximately half a year before the posting of the Ninety-five Theses, it is the first original publication that Luther himself saw through the press. Its success was instantaneous and widespread. As prominent a man as Johann von Staupitz lost no time in recommending it warmly. Luther's searching analysis of the human situation made a deep impression upon the many readers who, like the author's superior in the Augustinian order, gave the slender volume an enthusiastic reception. It is important to bear in mind that the book, besides stirring Luther's scholarly friends as well as the learned in general rather more than he himself had anticipated, found immediate favor also with the “common man” for whom it had primarily been written. There is no exaggeration in the claim that Luther's earliest publication straightway established him as one of the most widely read writers in the German tongue: his unparalleled success as an author can safely be said to have begun with the very first book he ever put out. The popular demand for “Die sieben Busspsalmen” reached such proportions that the second printing was already underway before the first had been completely finished. The book then went through a number of editions both regular and pirated: Wittenberg, Leipzig, Strassburg, and Erfurt printers published it between 1517 and 1525.
