Final answer:
The simile used by Homer to describe Athene's improvements on Odysseus typically compares the transformation to the change from night to day, symbolizing a dramatic improvement.
Step-by-step explanation:
The simile Homer uses to describe Athene's improvements on Odysseus is not provided in the provided excerpts, as these excerpts focus on mythology, the role of gods, and the giftedness of poets rather than the specific enhancements of Odysseus by Athene. In Homer's The Odyssey, Athene is known to make Odysseus appear more formidable and kingly to others, often enhancing his appearance to reflect dignity and garner respect, but the specific simile used to describe these improvements requires direct reference to the text of Homer's epic. However, a commonly referred simile compares the transformation to the change from night to day, symbolizing a dramatic improvement.
