Funny thing-- probably my two favorite artists of all time are a Dutch guy, and a non-Dalí Spanish guy. And there's a famous / punk-ish song about one of them, alleging he was "never an asshole," and yet from the books and lit I've read... he was totally an asshole.
And the other poor bloke's story only gets more complicated over the years, as in historians seem to be increasingly entertaining the idea that Vincent was in fact murdered... and they even know who the culprit was!
