I'm not a huge fan of Dali, though I much respect his work and even own a book on technique by him. But I'd forgotten that painting.
I'm not religious at all, but that painting is truly spiritual, mystical even. I think it must be his greatest work by far. What an inspiration, both artistically and religiously.
Dali is a guy who understood the classical painting methods, and swam against the stream by using them in the 20th century. Weirdly, my wife owns a watch which she sometimes wears in the shape of Dalis famous melting watches. It is kind of cute.
Dali's juxtapositon of style and subject were exquisitly detailed---he worked on some of these huge canvases for months.
