- Simile: 'like a thunderbolt.'
- Personification: 'the wrinkled sea.'
- Metaphor: 'mountain walls.'
A simile is used to compare the eagle's fall to a thunderbolt. Personification is used to describe the sea as wrinkled, giving it human-like qualities. And a metaphor is used to compare the eagle's position on the mountain to walls. These figures of speech enhance the imagery and add depth to the poem.
