Ein Bruderzwist in Habsburg, a play in German

According to Wikipedia: "Franz Seraphicus Grillparzer (January 15, 1791 – January 21, 1872), an Austrian dramatic poet, was born in Vienna... His fame was in accordance with the general tenor of his life; even in Austria a true understanding for his genius was late in coming, and not until the centenary of 1891 did the German-speaking world realize that it possessed in him a dramatic poet of the first rank; in other words, that Grillparzer was no mere Epigone of the classic period, but a poet who, by a rare assimilation of the strength of the Greeks, the imaginative depth of German classicism and the delicacy and grace of the Spaniards, had opened up new paths for the higher dramatic poetry of Europe."
