Anton Bruckner, whose 200th birthday we are celebrating this year, is considered a devout Catholic. But how did Bruckner's practised Christianity appear to his contemporaries? In an evening event, the Viennese musicologist and Catholic theologian Elisabeth Maier attempts to approach the spiritual life of the great symphonic composer. An impressive testimony to this are Bruckner's so-called "prayer records" in his notebooks. Musical aspects such as the possibility of a semantic meaning of quotations or the question of the dedication of the "Ninth Symphony" to "Dear God" will also be controversially discussed.
