In the Poetic Edda, Prose Edda, and Heimskringla, Hel is referred to as a daughter of Loki, and to " go to Hel " is to die.

In the Heimskringla book Ynglinga saga, written in the 13th century by Snorri Sturluson, Hel is referred to, though never by name.

Subsequently the Stockholm manuscript was translated into Swedish and Latin by Johan Peringskiöld ( by order of Charles XI ) and published in 1697 at Stockholm under the title Heimskringla, which is the first known use of the name.

The first part of the Heimskringla is rooted in Norse mythology ; as it advances, fable and fact all curiously intermingle, and it terminates in factual history.

Loki is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources ; the Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson ; the Norwegian Rune Poems, in the poetry of skalds, and in Scandinavian folklore.

The name Gandalf is found in at least one more place in Norse myth, in the semihistorical Heimskringla, which briefly describes Gandalf Alfgeirsson, a legendary Norse king from Eastern Norway and rival of Halfdan the Black.

Several historic works, known as the kings ' sagas were written in Norway and Iceland in the 12th and 13th centuries, the best known of which is Snorri Sturluson's Heimskringla ( c. 1220 ).

In Heimskringla it is claimed that Harald succeeded, on the death of his father Halfdan the Black Gudrödarson, to the sovereignty of several small, and somewhat scattered kingdoms in Vestfold, which had come into his father's hands through conquest and inheritance.

The unification of Norway is, according to a tale narrated in Heimskringla, something of a love story.

The Yngling " Fairhair dynasty " lineage introduced in Hversu Noregr byggðist (" How Norway was settled ") and the Orkneyinga and Heimskringla sagas suggests a line of Rollo going back to Fornjót, the primeval " king " who " reigned over " Finland and Kvenland.

These include the late 12th-century Norwegian synoptics – Historia Norwegiæ ( perhaps c. 1170 ), Theodoricus monachus ' Historia de antiquitate regum Norwagiensium ( c. 1180 ) and Ágrip af Nóregskonungasögum ( c. 1190 ) – and the later Icelandic kings ' sagas Orkneyinga saga ( c. 1200 ), Fagrskinna ( c. 1225 ), the Heimskringla ascribed to Snorri Sturluson ( c. 1230 ), Egils saga ( 1220 x 1240 ) and Óláfs saga Tryggvasonar en mesta ( c. 1300 ).

While Eirik's mother remains anonymous in the synoptic histories ( Ágrip ) and most of the Icelandic sagas, the Heimskringla ( c. 1230 ) claims that she was Ragnhildr, daughter of Eric, king of ( South ) Jutland.

Whatever one makes of the discrepancy, the sagas – including Heimskringla – are unanimous in making Haakon Eric's younger half-brother and successor.

However, a number of later sagas such as the Separate Saga of St. Olaf ( c. 1225 ), Heimskringla, Egils saga and Óláfs saga Tryggvasonar en mesta assert that Eirik sailed directly to Orkney, where he took the joint jarls into vassalage, collected forces and so set up a base which enabled him to organise several expeditions on overseas territory.

This was taken up by the later Icelandic sagas, Fagrskinna and Heimskringla ( ca.

Snorri Sturluson in Heimskringla outlines why these sagas are to be taken as being accurate, in reference to given inaccuracies in the literature on his own part, he states: “ that would be mockery and not praise ”.
