There's an article in today's Science Times about how two researchers (a medical illustrator and a neurosurgeon) have hypothesized that Michelangelo "embedded" in his Sistine Chapel fresco a human brain in God's neck.
All I can say boys is, keep your day jobs. Like many who step out of their fields of study, these two have a bit of an axe to grind and furthermore are proceeding from the wrong direction. Sure, Michelangelo was known for his in-depth anatomical study which included dissections. And there are similarities in the shapes they've picked out, but this is a coincidence. I'm sure if you looked hard enough you could find all sorts of shapes to fit your argument in the shadows and modeling that make up Michelangelo's masterpiece. The fact remains there is no logical explanation for why he'd put an organ on God's neck. It just doesn't make sense. But wait there's more, someone else spotted a kidney in another part of the ceiling.
