This is a test to see if the so-called "wisdom of the crowd" will actually be able to determine who the most beautiful woman of all time is. Of course, that woman may very well be a total unknown but since it's impossible to list every woman who's ever existed, and one is less likely to rank people they don't know, this list will obviously be restricted to people who've achieved a fair level of celebrity. A "fair level of celebrity" is defined by being famous enough to have a profile page on Wikipedia or IMDB. Historical figures are accepted IF pictures of them are generally accepted as accurate. Add your own suggestions and this should hopefully be an ever expanding list.
