" In the layout of the unfinished sketch, both of the main characters are placed in a higher position, while the angel turns out, the gaze bends down to look at the comedic God and seems to embrace him more closely," - London National Gallery described.

"These images were discovered because the substance used to paint them contained zinc, so it could be illuminated and displayed on the X-ray fluorescent map (MA-XRF)" - they explained.
