I have explored a number of different writers in recent years, but none ever comes close to Jack Vance's visual language talents; I would say, from my limited experience, that Clark Ashton Smith is Jack's only literary peer in this regard.
Was Jack also talented in the visual arts?? He was a good carpenter. I understand that he also tinkered around with pottery! Now, what was that all about?! Was it mainly his wife's interest? Was there ceramic wares in their home, made and decorated by Jack? Perhaps it was small a business ambition, to sell the wares?
Could Jack also draw and paint pictures?
