Divas of the world, unite! At long last, you can see -- though not kiss -- the hem of Maria Callas gown. The great soprano, whose voice, acting ability, and outsize personality set the standard for Elvis, Barbra (Streisand, dont you know), Cher, Liberace, and Madonna, returns through a choice selection of midcentury artifacts and mementos. Set off by glamorous accoutrements such as hand-stitched stage costumes and flashy jewels, the Maria Callas exhibit burnishes the persona of one of operas immortals. For the more scholarly (or serious), a trove of source and research material including letters, books and photographs hint at her life beyond the footlights. Born in New York City in 1923, Callas studied in Greece and made her name in Italy. Still a figure of debate and controversy in opera circles, and primarily known outside of the music world as the woman Aristotle Onassis left for Jackie Kennedy, Callas was a heroic as well as a tragic figure. Thirty-three years after Callas death, its not too late to join the chorus of admirers.
