Symbols in The Rime of the Ancient Mariner
The sailors ultimately blame the Mariner for their bad luck. As punishment, they make him wear the bird around his neck as a reminder of his crime. It is also a symbol of the burden of sin, and Coleridge is deliberately drawing a comparison between the Albatross and the cross on which Jesus Christ was crucified.
The rain in this section illustrates a key component in the rebirth, or change, of the Mariner. In literature, rain has many symbolic meanings, such as cleansing and renewal. Since the Mariner was finally able to sleep and awoke in the rain, Coleridge is showing us how the curse on the Mariner is breaking.
