hmm I think they both had issues...I mean Gogh killed himself so I would say that doesn't make him the most saine person even if it was Gauguin that cut his ear off. Say you don't believe Gauguin did it though, I found this exert in a letter Gauguin wrote to Gogh, "Naturally this band of pigs here find me quite mad, and I that rather pleases me because it proves to me that I am not." If others were questioning his sanity this sort of reaction to that seems abnormal to me. I am also recalling some Gogh letters with overly inflated self esteem between himself and a fellow artist, possibly Gauguin I can't remember. They were talking something about the isolation and of being 'such a great one' and how very few could relate. Gave me a good laugh wish I could find them to see if it was Gauguin...do you know if they exchanged self portraits? I remember that was the case as well with the particular artist that I am thinking he corresponded with. Great article, thanks for sharing!
