This intrigued me so I tried asking some AI; and in typical AI fashion, they gave me very wrong answers very convincingly.
Gpt4 is convinced it was Vermeer’s “Art of Painting”, and gave a very verbose - but completely wrong - description of how the woman was directing the painter’s arm. The BingGPT version even gave me links… to websites with completely unrelated paintings.
Google bard insists it was Goya’s “The Double Portrait”, and gave a very detailed analysis and critique of the painting. It’s very convincing, except for the fact that I couldn’t find a painting by that name by Goya…
So I’m sorry I couldn’t be of much help. I just found the whole thing amusing.
