Allusion 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.
By comparing the seabird to a Christian soul and describing how the bird helps get the ship to safety in the next stanza, Coleridge creates an allusion to the Biblical story of Noah’s Ark, in which a dove leads the ark to safety. Allusions occur when the author indirectly refers to a different story and leaves it up to the reader to make the connection.
