Examples of alliteration and their effect in rime of the ancient marrier

Samuel Taylor Coleridge's poem the Rime of the Ancient Mariner seems to be full of alliteration which helps the poem to rhyme and also helps the poem to flow smoothly and I would say makes it seem told with excitement. Some examples are "The guests are met, the feast is set" ie with met and set though the first letters are not the same the last letters "et" are so they rhyme nicely. Another similar example is " The wedding guest stood still" and  "The Mariner hath his will"  using "still" and "will" with similar spellings, and then "The ship was cheered, the harbour cleared" where the two words "cheered" and "cleared" sound very similar but have different meanings so the similar sounds tie the two thoughts together and seem to unify them.

What sisters? is it in a story?
