The night of the day she married Meneghini in Verona, she sailed for Argentina to sing at the Teatro Colón in Buenos Aires. Callas made her South American debut in Buenos Aires on May 20, 1949, during the European summer opera recess. "Aida", "Turandot" and "Norma" roles were directed by Serafin, supported by Mario Del Monaco, Fedora Barbieri and Nicola Rossi-Lemeni. These were her only appearances on this world-renowned stage. Her debut in the United States was five years later in Chicago in 1954, and "with the Callas "Norma", Lyric Opera of Chicago was born."
