The moon and the earth, attracted to each other, describe orbits around the sun. It is night, it is day. The moon dances orbiting the earth. At a certain point it reaches its closest approach, exciting the waters: full tide. In a few hours the described arc moves away: ebb. In incessant rotations the sun lights, extinguishes, and generates discontinuous atmospheres. The water, in the form of river or cloud, plays with the beams of light, creating multicoloured watercolours in the dusk that precedes sunset.
