Beowulf in Old English literally "bee wolf" i.e. "bee hunter," a kenning for "bear") is the conventional title of an Old English heroic epic poem consisting of 3182 alliterative long lines, set in Scandinavia, commonly cited as one of the most important works of Anglo-Saxon literature. It survives in a single manuscript known as the Nowell Codex. Its composition by an anonymous Anglo-Saxon poet is dated between the 8th and the early 11th century. In 1731, the manuscript was badly damaged by a fire that swept through the building which housed a collection of medieval manuscripts that had been assembled by Sir Robert Bruce Cotton. It fell into obscurity for many decades, and its existence did not become widely known again until it was printed in 1815 in an edition prepared by the Icelandic scholar Grimur Jonsson Thorkelin. In the poem, Beowulf, a hero of the Geats, battles three antagonists: Grendel, who has been attacking the resident warriors of the mead hall of Hroogar (the king of the Danes), Grendel's mother, and an unnamed dragon. After the first two victories, Beowulf goes home to Geatland in Sweden and becomes king of the Geats. The last fight takes place fifty years later. In this final battle, Beowulf is fatally wounded. After his death, his servants bury him in a tumulus in Geatland. The events described in the poem take place in the late 5th century, after the Anglo-Saxons had begun migration and settlement in England, and before the beginning of the 7th century, a time when the Saxons were either newly arrived or in close contact with their fellow Germanic kinsmen in Scandinavia and Northern Germany. The poem could have been transmitted in England by people of Geatish origins. It has been suggested that Beowulf was first composed in the 7th century at Rendlesham in East Anglia, as Sutton Hoo also shows close connections with Scandinavia, and also that the East Anglian royal dynasty, the Wuffings, were descendants of the Geatish Wulfings. Others have associated this poem with the court of King Alfred, or with the court of King Canute. The poem deals with legends, i.e., it was composed for entertainment and does not separate between fictional elements and real historic events, such as the raid by King Hygelac into Frisia, ca. 516. Scholars generally agree that many of the personalities of Beowulf also appear in Scandinavian sources (specific works designated in the following section). This does not only concern people (e.g., Healfdene, Hroogar, Halga, Hrooulf, Eadgils and Ohthere), but also clans (e.g., Scyldings, Scylfings and Wulfings) and some of the events (e.g., the Battle on the Ice of Lake Vanern). As far as Sweden is concerned, the dating of the events in the poem has been confirmed by archaeological excavations of the barrows indicated by Snorri Sturluson and by Swedish tradition as the graves of Ohthere (dated to c. 530) and his son Eadgils (dated to c. 575) in Uppland, Sweden."
