Comments: Here is the large central area of the mural. In the center is the Man, who is seen controlling machines, science, and technology. The two ellipses that cross diagonally behind the Man are like propellers, and the man is dressed like a pilot with gigantic mechanical wheels behind him. The ellipses represent the biological microcosm (in the Man's right side; our left) and the macrocosm of the stars and universe (on the Man's left side, our right). Below the Man are plants and fruits growing from the earth.
