It's like they're caught between being babies and people. Like the painters hadn't quite got down that the forms of babies are different. Or maybe it was on purpose, because they wanted to convey the divine intelligence of the angels?

Just viewed the image full size and noticed the milk spray coming out of the nipples! It's funny because it seems like such a serious painting and then the artist thought, "Milk lazers!!! Pew-pew-pew!"

And I'd like to know more about the pointy devil-squid monster being carried by the eagle.

I had to look up the word "putto." Thanks for growing my vocabulary. Next time I see someone with a loud unruly baby I'm going to say "Muzzle your putto, pronto!"
