Epanalepsis is a rhetorical device that involves repeating the initial word or phrase of a clause or sentence at the end of that same clause or sentence. This technique emphasizes the importance of the repeated phrase, creating a sense of closure or circularity in the argument. In Vergil's Aeneid, particularly in Book 1, Lines 494–578, this device can be seen in how it adds depth to character emotions and thematic elements, often highlighting key ideas or sentiments.
