Final answer:
The literary device used in the lines 'Bleeding drops of red' and the captain's 'lips are pale and still' is imagery, which employs descriptive language to create vivid pictures in the reader's mind.
Step-by-step explanation:
In the lines 'Bleeding drops of red' and the captain's 'lips are pale and still,' the literary device being used is imagery. Imagery is the use of descriptive language that appeals to the senses and paints a picture in the reader's mind. The term 'bleeding' evokes a sense of the vivid color and movement associated with the act of bleeding, which, in a metaphorical sense, adds intensity to the idea of 'drops of red'. The description of the captain's 'lips' as 'pale and still' creates a stark image of lifelessness and quiet, adding to the emotional weight of the scene. Such vivid descriptive imagery is used throughout literature to immerse the reader in the story and elicit a strong emotional response.
