Icelandic literature refers to literature written in Iceland or by Icelandic people. It is best known for the sagas written in medieval times, starting in the 13th century. As Icelandic and Old Norse are almost the same, and because Icelandic works constitute most of Old Norse literature, Old Norse literature is often wrongly considered a subset of Icelandic literature. However, works by Norwegians are present in the standard reader Sýnisbók íslenzkra bókmennta til miðrar átjándu aldar, compiled by Sigurður Nordal on the grounds that the language was the same.
The medieval Icelandic literature is usually divided into three parts:
There has been some discussion on the probable etymology of the term “Edda”. Most say it stems from the Old Norse term edda, which means great-grandmother, but some see a reference to Oddi, a place where Snorri Sturluson (the writer of the Prose Edda) was brought up.
The Elder Edda or Poetic Edda (originally attributed to Sæmundr fróði, although this is now rejected by modern scholars) is a collection of Old Norse poems and stories originated in the late 10th century.
Although these poems and stories probably come from the Scandinavian mainland, they were first written down in the 13th century in Iceland. The first and original manuscript of the Poetic Edda is the Codex Regius, found in southern Iceland in 1643 by Brynjólfur Sveinsson, Bishop of Skálholt.
The Younger Edda or Prose Edda was written by Snorri Sturluson, and it is the main source of modern understanding of Norse mythology and also of some features of medieval Icelandic poetics, as it contains many mythological stories and also several kennings. In fact, its main purpose was to use it as a manual of poetics for the Icelandic skalds.
