I was first introduced to Hockney's theory in a New Yorker article from 2000. The full article isn't available online unless you have a subscription but you can find a summary of sorts here: https://www.newyorker.com/magazine/2000/01/31/the-looking-glass https://www.newyorker.com/magazine/2000/01/31/the-looking-gl... It looks like the article preceded publication of Hockney's book and originated at a time when he was still rehearsing and refining his argument. His main antagonists in the article are the art historians who come off a bit like stuffy reactionaries. I was firmly in Hockney's camp by the time I had finished the article. It was one of those ideas that changed the way I look at the world slightly. Never read the book. Tim's Vermeer was the coup de grace for me and I was gratified to see Hockney make a cameo in it.
