It's a bit strange though, that the artist could get the woman's body so beautifully in proportion, but anybody can see that those wings would hardly be big enough to fly a pigeon. And the angels, or whatever they are, would need tail-feathers as well for any sort of control in their flying.
Or was this an early depiction of experiments in genetic engineering, when they tried to make wise kids by mixing human and Owl DNA, but they got the wrong bits of the DNA. The kids seem happy enough in their ignorance, but she looks a bit disappointed with the results. I think she's debating with herself whether to try again with something else maybe fox DNA to make them sly so that they can grow up to be bankers. Wasn't there another painting later that showed kids with bushy tails running round round their mum?
