In Homer's stories, sometimes characters are described using words or phrases that highlight their important qualities. These words or phrases are called epithets, which are like special nicknames. For example, when talking about the character Achilles, Homer often describes him as "swift-footed." This reminds us that Achilles is a really fast runner and emphasizes this important trait. Similarly, Helen of Troy is often called "the fair-haired" because her hair is a special feature that makes her stand out. These epithets are used as a way to make the characters more memorable and to emphasize the traits that define them.
