Mathis der Maler (opera) Mathis der Maler ("Matthias the Painter") is an opera by Paul Hindemith. The opera's genesis lay in Hindemith's interest in the Reformation. The work's protagonist, Matthias Grünewald, was an actual historical figure who flourished in that era, and whose art, in particular the Isenheim Altarpiece, inspired many creative figures in the early 20th century, including Joris-Karl Huysmans's novel "Là-bas".
