for abandoning her. He welcomes his imperial consort, Anna, and takes

excites the impatient lover to jealousy of Frederick. Ridolpho is
banished court for murder.

Act IV. Frederick is distressed by Wirtemberg's discontent. The Empress,

suspicions. Adelaid overhears Ridolpho and Waldec plotting to slay
Frederick, but hesitates to accuse her own brother. Wirtemberg

leave her forever.

in mortally wounding Frederick, who dies amid tears.
