Eric Haraldsson, nicknamed Bloodaxe and Brother-Slayer, was a Norwegian king. He ruled as King of Norway from 932 to 934, and twice as King of Northumbria: from 947 to 948, and again from 952 to 954.

A skald, or skáld is one of the often named poets who composed skaldic poetry, one of the two kinds of Old Norse poetry in alliterative verse, the other being Eddic poetry. Skaldic poems were traditionally composed to honor kings, but were sometimes extempore. They include both extended works and single verses (lausavísur). They are characteristically more ornate in form and diction than eddic poems, employing many kennings, which require some knowledge of Norse mythology, and heiti, which are formal nouns used in place of more prosaic synonyms. Dróttkvætt metre is a type of skaldic verse form that most often use internal rhyme and alliteration.
