Which the function of the citations present Coleridge in the romance? Explain to them.
There is an excerpt in the novel from Coleridge's Rime of the Ancient Mariner which alludes to something horrible following you and you having to keep looking over your shoulder. It refers to the creature in Frankenstein, and the evil in the world which causes people to disrespect fellow creatures of God's making. The albatross, the sea snakes, the other humans on the mariner's ship.
Mary Shelley's father William Goodwin was very good friends with Coleridge. Mary Shelley hears Coleridge read his Rime of the Ancient Mariner as a little girl. She later wrote about how the images of this haunted her years after hearing it.
The citation seen in the novel from Rime of the Ancient Marinerserves as foreshadowing.Shelley using an allusion to Coleridge emphasizes that Frankenstein is Romantic literature. Coleridge being one of the stars of this era of literature.
"Like one who, on a lonely road, Doth walk in fear and dread, And, having once turned round, walks on, And turns no more his head; Because he knows a frightful fiend Doth close behind him tread."
Clearly the "frightful fiend" is the creature that will stalk Victor until he comes through the demands of the creature. The concept of "turns no more his head," refers to idea that once the creature is brought to life the doom and gloom that will follow is inevitable.
This excerpt comes in Chapter 5 of the novel. This is the chapter where Victor is describing how he feels after creating the creature. He mentions wanting to avoid the creature although like the Coleridge excerpt implies, this is impossible.
