Old Norse poetry
Old Norse poetry encompasses a range of verse forms written in Old Norse, during the period from the 8th century (see Eggjum stone) to as late as the far end of the 13th century. Most of the Old Norse poetry that survives was preserved in Iceland, but there are also 122 preserved poems in Swedish rune inscriptions, 54 in Norwegian and 12 in Danish. Poetry played an important role in the social and religious world of the Vikings. In Norse mythology, "Skáldskaparmál" tells the story of how Odin brought the mead of poetry to Asgard, which is  an indicator of the significance of poetry within the contemporary Scandinavian culture. Old Norse poetry is characterised by alliteration, a poetic vocabulary expanded by heiti, and use of kennings. An important source of information about poetic forms in Old Norse is the Prose Edda of Snorri Sturluson. Old Norse poetry is conventionally, and somewhat arbitrarily, split into two types—Eddaic poetry (also sometimes known as "Eddic" poetry) and skaldic poetry. Eddaic poetry includes the poems of the Codex Regius and a few other similar ones. Skaldic poetry is usually defined as everything else not already mentioned. Metrical forms. Old Norse  poetry has many metrical forms. They range from the relatively simple fornyrðislag to the deeply complex dróttkvætt, the "courtly metre". In Eddic poetry, the metric structures are generally simple, and are almost invariably ljóðaháttr or fornyrðislag. Ljóðaháttr, (known also as the "metre of chants"), because of its structure, which comprises broken stanzas, lends itself to dialogue and discourse. Fornyrðislag, "the metre of ancient words", is the more commonly used of the two, and is generally used where the poem is largely narrative. It is composed with four or more syllables per line. Other metrical forms include Eddaic poetry. The Eddaic  poems have the following characteristics. Skaldic poetry. The skaldic poems have the following characteristics.
