thanks to starduster provide me the fetus picture below
this is an icon on wm site
and I find the shape of the fetus looks like the part of the chamber12 painting,it is obviously not a coincidence.
Is this fetus a metaphor of our humankind? Mankind in the womb of universe(first source) to be taught by wingmakers.
the 1st poem of chamber12 is "wingmakers" ,"to watch the wingmakers craft my wings"
I guess chamber12 painting depicted the process of "craft wings of mankind"
may this help you.
