The lady portrayed above was a very famous dancer who became quite wealthy later in life (look at the jewelry on her!). Judging from this painting, she was not in her youth when she posed for the painter. Perhaps this is around the time she greatly supported Ravel when he most needed this support during his terminal illness. In any case, her debut, much earlier, proved scandalous not only because the composer's music was somewhat "modernistic" but mainly because, in the course of this very famous dance in the classical repertoire, she actually was asked to strip naked..... The famous dance was performed earlier in the twentieth century, long before Ravel's Bolero.
