The Dove, No. 12, from Group IX Series SUW/UW1915 by Hilma Af Klint

Inside the Saturn-like gray orb at the center of The Dove No. 12 sits a smaller circle with a delicately painted angel touched with what looks like gold leaf on the wings. I imagine it is a floating stone reliquary holding the sacred remains at its heart.
