Letter from Zemlinsky to Schoenberg, New York, February 1940. It was the last letter written by the fatally ill Zemlinsky to Schoenberg. As he could no longer write himself, he probably dictated the letter to his wife. At the end of 1939 the couple had decided to move to California as Zemlinsky saw no hope of recovering from his illness in New York. The removal did not come about as Zemlinsky soon suffered a relapse. The opera libretto referred to is Circe based on a text by Irma Stein-Firner and Walter Firner. Zemlinsky was only able to compose a little more than one act of this opera.
