Hávamál, (Old Norse: "Sayings of the High One [Odin]") a heterogeneous collection of 164 stanzas of aphorisms, homely wisdom, counsels, and magic charms that are ascribed to the Norse god Odin. The work contains at least five separate fragments not originally discovered together and constitutes a portion of the Poetic Edda. Most of the poems are believed to have been composed in Norway in the 9th and 10th centuries.The collection begins with poetry concerning rules of social conduct. Of perhaps greater general interest are the myths about Odin's erotic affairs, especially his amorous adventure leading to the theft of the precious mead. In another poem, the Vaf rúðnismál ("Lay of Vaf rúðnir"), Odin engages in a contest of wits with Vaf rúðnir, an immensely wise giant. The poem, in the form of question and answer, tells of the cosmos, gods, giants, the beginning of the world, and its end. The latter part contains the strange myth of how Odin acquired the magical power of the runes (alphabetical characters) by hanging himself from a tree and suffering hunger and thirst for nine nights. The Hávamál ends with a list of magic charms.
