Final answer:
The line from 'Elegy Written in a Country Churchyard' demonstrating personification is 'Perhaps in this neglected spot is laid / Some heart once pregnant with celestial fire;'. The heart is described as being filled with divine inspiration, a human quality, suggesting once vibrant lives now forgotten.
Step-by-step explanation:
Personification in Poetry
The line from "Elegy Written in a Country Churchyard" that best demonstrates personification is "Perhaps in this neglected spot is laid / Some heart once pregnant with celestial fire;" Personification is a literary device where human characteristics are attributed to non-human entities. In this line, a heart (which symbolically represents a person's essence or passion) is described as being 'pregnant with celestial fire,' implying it was once filled with inspired life or divine creativity, a human characteristic. This usage imbues the heart with vitality and potential, despite its current neglected state in the grave. The line is steeped in emotion and assigns a human attribute - the capacity to be filled with fiery inspiration - to a metaphorical heart. It contrasts the forgotten graves with the once vibrant lives of those buried there, suggesting unrecognized potential that once burned like a fire within them.
Other examples of personification can be seen in the poetry of Wordsworth and Keats. Wordsworth's "I wandered lonely as a cloud," for instance, describes daffodils as dancing, a human action, giving them an active, joyful presence. Similarly, Keats's "Ode on a Grecian Urn" speaks to the urn itself, addressing it as if it could respond, and calling it a 'bride of quietness' and a 'foster-child of silence and slow time.' This gives the inanimate urn qualities of life, silence, and timelessness.
