In this case it might have been the only clue that would have allowed me to get it.
It is a similar thing when you talk about someone in your class, to family or friends or something, and they don;t know who you mean. And you answer the tall guy. Immediately they know who you mean, that does not mean that is all there is to that person, there might be lots of interesting things about him
If the description was "person who suffered and achieved a lot", I doubt even 1% would get it, there are endless possibilities. Even if you would add "artist"chances are slim
