Anna Pavalova in Autumn Bacchanale, c1910 They first appeared in a classical pas de deux, performed with such style and beauty that they took ten curtain calls, an extraordinary number for a music hall. Nothing prepared the audience for what came next. Gone were Pavlova's tutu and Mordkin's ballet costume, gone her pointe shoes. In Greek tunics and sandals, they flung themselves onto the stage in the 'Autumn Bacchanal', one of the most tempestuous and passionate dances ever staged.
