Beowulf is an Old English epic poem consisting of 3,182 alliterative lines. It may be the oldest surviving long poem in Old English and is commonly cited as one of the most important works of Old English literature. A date of composition is a matter of contention among scholars; the only certain dating pertains to the manuscript, which was produced between 975 and 1025. The author was an anonymous Anglo-Saxon poet, referred to by scholars as the "Beowulf poet". The poem is set in Scandinavia. Beowulf, a hero of the Geats, comes to the aid of Hrothgar, the king of the Danes, whose mead hall in Heorot has been under attack by a monster known as Grendel. After Beowulf slays him, Grendel's mother attacks the hall and is then also defeated. Victorious, Beowulf goes home to Geatland (Götaland in modern Sweden) and later becomes king of the Geats. After a period of fifty years has passed, Beowulf defeats a dragon, but is mortally wounded in the battle. After his death, his attendants cremate his body and erect a tower on a headland in his memory. The full poem survives in the manuscript known as the Nowell Codex. It has no title in the original manuscript, but has become known by the name of the story's protagonist.[4] In 1731, the manuscript was badly damaged by a fire that swept through Ashburnham House in London that had a collection of medieval manuscripts assembled by Sir Robert Bruce Cotton.[5] The Nowell Codex is currently housed in the British Library. The poem deals with legends, was composed for entertainment, and does not separate between fictional elements and historic events, such as the raid by King Hygelac into Frisia. Though Beowulf himself is not mentioned in any other Anglo-Saxon manuscript,[10] scholars generally agree that many of the other figures referred to in Beowulf also appear in Scandinavian sources. (Specific works are designated in the following section).[11] This concerns not only individuals (e.g., Healfdene, Hroðgar, Halga, Hroðulf, Eadgils and Ohthere), but also clans (e.g., Scyldings, Scylfings and Wulfings) and certain events (e.g., the Battle on the Ice of Lake Vänern). The dating of the events in the epic poem has been confirmed by archaeological excavations of the barrows in Uppland, Sweden, 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).[12][13][14] In Denmark, recent archaeological excavations at Lejre, where Scandinavian tradition located the seat of the Scyldings, i.e., Heorot, have revealed that a hall was built in the mid-6th century, exactly the time period of Beowulf.[15] Three halls, each about 50 metres (160 ft) long, were found during the excavation. The majority view appears to be that people such as King Hroðgar and the Scyldings in Beowulf are based on historical people from 6th-century Scandinavia.[16] Like the Finnesburg Fragment and several shorter surviving poems, Beowulf has consequently been used as a source of information about Scandinavian figures such as Eadgils and Hygelac, and about continental Germanic figures such as Offa, king of the continental Angles. 19th-century archaeological evidence may confirm elements of the Beowulf story. Eadgils was buried at Uppsala according to Snorri Sturluson. When Eadgils' mound (to the left in the photo) was excavated in 1874, the finds supported Beowulf and the sagas. They showed that a powerful man was buried in a large barrow, c. 575, on a bear skin with two dogs and rich grave offerings. These remains include a Frankish sword adorned with gold and garnets and a tafl game with Roman pawns of ivory. He was dressed in a costly suit made of Frankish cloth with golden threads, and he wore a belt with a costly buckle. There were four cameos from the Middle East which were probably part of a casket. This would have been a burial fitting a king who was famous for his wealth in Old Norse sources. Ongentheow's barrow has not been excavated. **
