The theme of dejection is a significant component of "dark" Romanticism. The most
influential exploration of it in the canon of British Romanticism is that found in
"Dejection: An Ode" by Coleridge, whose "Rime of the Ancient Mariner" has already
figured in the structure of the novel (I:L2:6). Of the major Romantic poets (besides
Percy Bysshe Shelley), Coleridge seems to have had the greatest impact on Mary Shelley's
writing in Frankenstein.
