What does the vision of the plough against the sun symbolize?

The plow symbolizes the connection between human culture and the natural landscape. The scene where the plow sits beneath the setting sun gives us a sense of the melding of man's machine and the nature's majesty. The plow does not look out of place rather it compliments man’s place in the natural world. The plow seems an extension of the landscape until the sun sets. As the scene grows darker the plow seems to disappear thus reflecting the enormity of the natural world over man's existence.
