“ Between 1827 and 1832 Immermann redeemed his good name by a series of historical tragedies, Das Trauerspiel in Tirol (1827) , Kaiser Friedrich II. (1828) and a trilogy from Russian history, Alexis (1832) . His masterpiece is the poetic mystery, Merlin (1831) , a noble poem, which, like its model, Faust, deals with the deeper problems of modern spiritual life. Immermann’s important dramaturgic experiments in Düsseldorf are described in detail in Düsseldörfer Anfänge (1840) . More significant is his position as a novelist. ”
