Window 2 Scene 4 - The Act of Creation

First Act of Creation - dividing light from darkness. The Light is an abstract concept, so it's also depicted in abstract way. In bottom-left corner we can distinguish the shape of a hand, symbolizing God's hand, which brings a movement and dynamism to the composition. "Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. And God said, ?Let there be light,?  (Genesis 1,2)
