Iceland's most versatile literary genius, Snorri Sturluson (1179-1241) was born in western Iceland, the son of a great chieftain. Early in his career, he won a reputation at home and in Norway for his poetic talents. Later he traveled to Norway and wrote about the lives of the kings: "Heimskringla Saga, Egil's Saga, "and "Saint Ol?f's Saga, "a work unsurpassed in Icelandic prose.
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.
