It is a long poem. It was written by Samuel Taylor Coleridge in 1797. Its topic is the experiences of a sailor. It is relating to Christianity and supernatural. Its theme concerns potential consequences of a single unthinking casually. Yet this impulsive, destructive act is his undoing.
Coleridge believed that seeds of destruction and creation are contained each within the other. Destruction leads to the creation of something new. Loss of the Mariner’s ship, and his own former self ultimately leads to regeneration of the Mariner.
