Imagery is a literary device that uses vivid and descriptive language to create mental pictures in the reader's mind. It appeals to the senses, allowing readers to visualize scenes, hear sounds, or even feel emotions conveyed through words. In Vergil's 'Aeneid', especially in Book 1, Lines 418โ440, imagery enhances the emotional depth and vividness of the narrative, illustrating both the beauty of the natural world and the turmoil of human experience.
