Imagery Part 4

As the Ancient Mariner drifts on the ocean, the natural world becomes more threatening. His surroundings - the ship, the ocean, and the creatures within it - are "rotting" in the heat and sun, but he is the one who is rotten on the inside. Meanwhile the sailors' corpses refuse to rot, and their open eyes curse him continuously, giving the Ancient Mariner a visible manifestation of the living death that awaits him. He will age, but his body will never rot enough to release his soul; his eye will glitter forever with the horror of damnation. As the Ancient Mariner floats, he becomes delirious, unable to escape his overwhelming loneliness even by sleeping: "I closed my lids, and kept them close, / And the balls like pulses beat; / For the sky and the sea, and the sea and the sky / Lay like a load on my weary eye..." His depravity has even denied him the comfort of prayer.

Ironically, it is the "slimy", "rotten" creatures themselves that finally comfort the Ancient Mariner and allow him to pray. Until this moment, Coleridge's imagery has underscored the overbearing nature of the Ancient Mariner's environment: it is hot, salty, pungent, and "rotten." However, his surroundings - and the imagery that accompanies them - turn cool in the moonlight. Coleridge compares the moonlight to a gentle frost, connecting it to the serenity of the "rime": "[The moon's] beams bemocked the sultry main, / Like April hoar-frost spread." Aglow in the moonlight, the sea creatures begin frolicking, rather than churning nastily; creatures of a beautiful, supernatural world, they "moved in tracks of shining white, / And when they reared, the elfish light / Fell off in hoary flakes...I watched their rich attire; / Blue, glossy green, and velvet black, / They coiled and swam; and every track / Was a flash of golden fire." Whereas Coleridge's descriptions of the ghost ship, sun, and sailors are replete with spare, harsh imagery, he describes the water-snakes in decadent, lush terms. Only when the Ancient Mariner is able to appreciate the beauty of the natural world is he granted the ability to pray - and, it is implied, eventually redeem himself. Earlier in the work, the desiccated setting represented the Ancient Mariner's moral drought, but the moment he begins to view the natural world benevolently, his spiritual thirst is quenched: "A spring of love gushed from my heart." As a sign that his burden has been lifted, the Albatross - the burden of sin - falls from his neck: it is no longer his cross to bear.
