Each poem in the Elder Edda must be considered individually as to its narrator and point of view. The composite Sayings of the High One gives the impression of more than one narrator. The simple narratives use a third person point of view: except for the occasional lines like: "Hlorridi's heart leaped with laughter/ Then grew hard when he saw his hammer." Characters' thoughts and emotions are revealed entirely through their own words and actions. For example, Freyja's rage is clear from her actions in the Lay of Thrym: "Freyja snorted in such a fury / she made the hall of the Aesir shake." Two of the lays, the Sibyl's Prophecy and the Prophecy of Gripir by virtue of being prophecies, have an omniscient narrator. In some of the question and answer dialogues, for example, the The Lay of Vafthrudnir, the purpose is to provide specific information, but the dramatic and ironic interest that keeps the exchange from descending into a glossary is that while one character only appears to be omniscient the other truly is omniscient.
