LiteratureMany of the important poems were composed in the 10th through 12th century. These were part of the oral tradition, and were kept alive by repetition as they were passed from one generation to another.
Poetry was likely a major form of entertainment for the Norse. Poets were held in high regard, not only for their ability to improvise poetic entertainment on the spot, but also because they were the repository of the shared cultural experience. They were the vessel through which the culture was passed from generation to generation. Once committed to poetry, a thought was expected to last "as long as the land is inhabited" or "as long as the Norse language is spoken".
Beginning in the 12th century, educated men in Iceland, where the oral tradition was strongest, began to write down the important stories. Iceland was unique among European countries at this time in having a population comprised of a large number of relatively free, land-owning farmers. These men had the means to commission the creation of books in their own language, rather than in Latin as was the rule throughout the rest of Europe. The oral story-telling tradition of the Icelanders also favored writings in the vernacular. A wide variety of material was written down in the Icelandic language.
One of the first books was Íslendingabók, a history of Iceland written circa 1130, probably by Ari fróđi. Law books were written around this time when Icelandic legislators decided to write down the laws which before had been committed to memory. Scholars wrote books describing how to use Roman letters to represent the sounds of the Icelandic language. The First Grammatical Treatise was followed by three others. The genealogy and history of Icelandic settlers were written down in Landnámabók.
European literature was translated into Icelandic, including stories of the lives of saints, and learned books on topics including astronomy, natural history, and geography. Travel books were written by Icelandic visitors to Europe.
New stories were written to commemorate the exploits of kings or other great leaders. Some of these books were in the form of histories, such as Heimskringla, a history of the kings of Norway. Others described contemporary events, such as the sagas of bishops, and the Sturlunga saga, a compilation of sagas describing the events in the turbulent times when the sons of Sturla Ţórđarson were changing the political landscape of the Iceland.
