Conrad Gerler's instruments, too, were much sought after. In 1460, for instance, we find Charles the Bold, Duke of Burgundy, sending for three lutes for the players at his Court. An extremely good and interesting collection of old musical instruments will be found in the _German Museum_. In this connection should also be noted there a picture of the Meistersingers' singing school.[50] The reputation of the Nuremberg school of poetry and singing was greatly enhanced by Hans Sachs. Remarkable for his own personality and literary fertility, he was also famous for reducing all the rules of the Meistersingers to writing, in a code which lasted till 1735. But, in spite of his attention to rules, he, at any rate, showed some poetic and original talent. It is for this reason that Wagner makes him, in "Die Meistersinger," recognise the real poetry in Walter, though the latter's impassioned song does not conform with all the artificial rules of the Guild, mere paper rules which added nothing to the sound or rhythm of the words. For, as all the world knows, Hans Sachs has achieved a second lease of life on men's lips, through the genius of Richard Wagner, dramatist, poet, satirist, and wonderful musician, who, in this opera, laughs at the conceit of the Incorporated Poets in assigning an extravagant antiquity to their Guilds, and at their pedantic sacrifice of matter to form. No more vivid and humorous picture of mediæval German life and of the people of quaint old Nuremberg has ever been drawn. Though "Die Meistersinger von Nürnberg" was not published till 1867, Wagner had already as early as 1851 sketched out the plan of an opera which was to display the triumph of genius and genuine passion over pedantry and conventionalism in art. The passage[51] from "Eine Mittheilung an meine Freunde" is worth quoting here.
