Salome was quite the gal, as this Wikipedia entry indicates. Dancing, sexiness, murder and other factors contribute to rich grounds for artists to exploit. I was even about to use the work "beauty," in the last sentence but did not. That's because no one since her days has had any idea what she looked like. The best we have is the image on the coin shown below, and it isn't very inspiring.
This lack of information was never a barrier to artists who were handed subject matter to spare plus unlimited freedom to imagine her. Below are some examples of her depiction in approximate chronological order.
And which Salome has the most appeal? Beats me. I'll take any of them except, perhaps, the image from Beardsley (nice drawing that it is). And the one on the coin.
