[1] The period corresponds to the Germanic Wars in terms of historiography, and to the Germanic Iron Age in terms of archaeology, spanning the early centuries of the 1st millennium, in particular the 4th and 5th centuries, the period of the final collapse of the Western Roman Empire and the establishment of stable "barbarian kingdoms" larger than at the tribal level (the kingdoms of the Visigoths and Ostrogoths, the Franks and the Burgundians, and the Anglo-Saxon settlement of Britain).
The Germanic peoples at the time lived mostly in tribal societies.
Ker would thus extend the Germanic heroic age to the point of Christianization, to the inclusion of the Scandinavian Viking Age and culminating in the Icelandic family sagas of the 13th century.
The Prose Edda itself originated as a handbook for skaldic poets, compiled by Snorri Sturluson more than 200 years after the Christianisation of Iceland, because poetic tradition at that time was threatened by extinction.
Identifiable historical characters appearing in Germanic heroic poetry, notably in the Völsung and Tyrfing cycles, include: A number of tribal kings of the 5th to 6th centuries featured in heroic poetry are likely historical, but only rarely can this be established from independent historiographic traditions, as in the case of Hygelac (died c. 521), king of the Geats, who appears both in the heroic poem Beowulf and in historiographic sources such as the Liber Historiae Francorum.
