Snorri Sturluson's fame as a historian---his main work is the 16 sagas included in Heimskringla (c.1230), a monumental history of Norway from its beginning until 1177---lies both in his critical approach to sources and in his fine, realistic exposition of event and motivation. A similar combination of scholarly and imaginative talent is seen in The Prose Edda (c.1220). Intended to be a handbook in skaldic poetry, it preserves invaluable mythological tales that were on the verge of being forgotten even in Sturluson's time. A large part of what we know about Nordic mythology stems from his Edda. The bibliography that follows also lists the anonymous Egil's Saga (1200--30), which many expert Scandinavian medievalists (e.g., Sigurdur Nordal and Bjorn M. Olsen) attribute to Sturluson. It is a fascinating account of life in Norway, England, and Iceland and of the poet-warrior Egil, whose skaldic verse is renowned for its unusual emotional and personal qualities. Snorri Sturluson's own life was as eventful as those about whom he wrote. Returning to Iceland from exile in 1239, he again became deeply involved in serious power struggles and was murdered in 1241.
In autumn, King Halfdan proceeded to Vingulmark. One night when he was there in guest quarters, it happened that about midnight a man came to him who had been on the watch on horseback, and told him a war force was come near to the house. The king instantly got up, ordered his men to arm themselves, and went out of the house and drew them up in battle order. At the same moment, Gandalf’s sons, Hysing and Helsing, made their appearance with a large army. There was a great battle; but Halfdan being overpowered by the numbers of people fled to the forest, leaving many of his men on this spot. His foster-father, Olver Spake (the Wise), fell here. The people now came in swarms to King Halfdan, and he advanced to seek Gandalf’s sons. They met at Eid, near Lake Oieren, and fought there. Hysing and Helsing fell, and their brother Hake saved himself by flight. King Halfdan then took possession of the whole of Vingulmark, and Hake fled to Alfheimar.
