The events in the poem take place over most of the sixth century, and feature no English characters. Some suggest that Beowulf was first composed in the 7th century at Rendlesham in East Anglia, as the Sutton Hoo ship-burial shows close connections with Scandinavia, and the East Anglian royal dynasty, the Wuffingas, may have been descendants of the Geatish Wulfings. Others have associated this poem with the court of King Alfred the Great or with the court of King Cnut the Great.
The poem blends fictional, legendary and historic elements. Although Beowulf himself is not mentioned in any other Anglo-Saxon manuscript, scholars generally agree that many of the other figures referred to in Beowulf also appear in Scandinavian sources (specific works are designated in the section titled "Sources and analogues"). 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 between Eadgils and Onela). The raid by King Hygelac into Frisia is mentioned by Gregory of Tours in his History of the Franks and can be dated to around 521.
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. 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. 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 (Gamla Uppsala, Sweden) according to Snorri Sturluson. When the western mound (to the left in the photo) was excavated in 1874, the finds showed that a powerful man was buried in a large barrow, c. 575, on a bear skin with two dogs and rich grave offerings. The eastern mound was excavated in 1854, and contained the remains of a woman, or a woman and a young man. The middle barrow has not been excavated.
