The sources of The Ancient Mariner are many and varied. It all started with John Cruikshank's dream of a skeleton ship and continued with Wordsworth's suggestion of the killing of an albatross as the cause of spectral persecution.
Coleridge had an early interest in the Wandering Jew and the origin of evil (his first thoughts can be found is own earlier literary works such as Osorio and The Wanderings of Cain). Also the author was a real fan to the traditions of folk and Gothic ballads. There are hundreds of other influences, most of them from books which Coleridge either knew or is supposed to have known..
Yet it must be said that whatever Coleridge touches he transmutes; whatever he borrows, or imitates, from earlier writers is transformed, as if it was touched by a wizard’s wand, into something rich and strange.
