Maria Callas is one of the greatest opera singers of the 20th century, a universal singer. ``Four voices in one woman,'' wrote ``The New York Times.''
After the appearance of Herbert von Karajan and Leonard Bernstein, Luchino Visconti and Franco Zeffirelli, every performance with Maria Callas's participation became a major event. The Queen of La Scala _ La Divina! _ was christened by critics.
Callas turned opera into a real dramatic theater, ``even a simple Gamma expressed joy, sorrow or sadness in Maria's performance.''
After breaking up with the famous Greek millionaire Aristotle Onassis (Onassis married President Kennedy's widow Jacqueline Kennedy), Callas lost her voice.
Maria Callas died in Paris, completely alone, forgotten by everyone. Her ashes, according to her will, were scattered over the Aegean Sea.
