It is 500 years since Luther nailed his 95 theses concerning indulgences to the doors of the Castle Chapel in Wittenberg, which at that time served as the university’s notice board. The rapid dissemination of his message – initially in print and later also by means of music – set in motion a revolutionary machine whose field of influence stretched far beyond religion alone. A somewhat delayed but no less innovative reaction developed in response: the Counter-Reformation.
