In the poem 'Inchcape Rock' by Robert Southey, the captain strikes a blow at a beacon of Christianity by removing a safety bell placed by a bishop whom all respect on a dangerous cliff at sea. The captain doesn't want anyone to bless the bishop for their safety any more, so he cuts off the bell which sinks to the bottom of the sea. As the crime is against a Christian representative the act is seen perhaps as an evil one deserving of punishment. Ironically, when the captain returns he does not see the perilous sharp rock and there is no bell to warn him of it and his ship sinks, while the devil laughs below the waves. One of the most noticeable poetic devices in this poem is the heavy use of rhyme. This occurs at the end of lines and has the effect of giving the poem a sing-song effect like a sea-shanty. These types of poems are easy to remember and thus narrate. Other devices to look out for in poetry are below:
