Epithets in Homer
A characteristic of Homer's style is the use of epithets, as in "rosy-fingered" Dawn or "swift-footed" Achilles. Epithets are used because of the constraints of the dactylic hexameter (i.e., it is convenient to have a stockpile of metrically fitting phrases to add to a name) and because of the oral transmission of the poems; they are mnemonic aids to the singer and the audience alike.
