Framed by a narrow mass of terrestrial along the edge and then flying figures in the middle, the bright void straight up there in the center of the picture is full of light. That’s god Apollo with the yellow nimbus about to set out in the morning in Allegory of the Planets and Continents (1752) by Giovanni Battista Tiepolo. The picture has a powerful vertical effect, but if you think about it from a horizontal position, it sort of looks like a carpet.
