If we consider the position of the authors or recorders of these sagas in relation to the views they present in regard to Odainsaker and the Glittering Plains, then we find that they themselves, with or without reason, believe that these views are from a heathen time and of heathen origin. The saga of Erik Vidforle states that its hero had in his own native land, and in his heathen environment, heard reports about Odainsaker. The Miklagard king who instructs the prince in the doctrines of Christianity knows, on the other hand, nothing of such a country. He simply conjectures that the Odainsaker of the heathens must be the same as the Paradise of the Christians, and the saga later makes this conjecture turn out to be incorrect.
The author of Hervor's saga mentions Odainsaker as a heathen belief, and tries to give reasons why it was believed in heathen times that Odainsaker was situated within the limits of Gudmund's kingdom, the Glittering Plains. The reason is: "Gudmund and his men became so old that they lived through several generations (Gudmund lived five hundred years), and therefore the heathens believed that Odainsaker was situated in his domain."
The man who compiled the legend about Helge Thoreson connects it with the history of King Olaf Trygveson, and pits this first king of Norway, who laboured for the introduction of Christianity, as a representative of the new and true doctrine against King Gudmund of the Glittering Plains as the representative of the heathen doctrine. The author would not have done this if he had not believed that the ruler of the Glittering Plains had his ancestors in heathendom.
The saga of Thorstein Bæarmagn puts Gudmund and the Glittering Plains in a tributary relation to Jotunheim and to Geirrod, the giant, well known in the mythology.
Saxo makes Gudmund Geirrod's (Geruthus') brother, and he believes he is discussing ancient traditions when he relates Gorm's journey of discovery and Hadding's journey to Jotunheim. Gorm's reign is referred by Saxo to the period immediately following the reign of the mythical King Snö (Snow) and the emigration of the Longobardians. Hadding's descent to the lower world occurred, according to Saxo, in an antiquity many centuries before King Snow. Hadding is, in Saxo, one of the first kings of Denmark, the grandson of Skjold, progenitor of the Skjoldungs.
The saga of Erik Vidforle makes the way to Odainsaker pass through Syria, India, and an unknown land which wants the light of the sun, and where the stars are visible all day long. On the other side of Odainsaker, and bordering on it, lies the land of the happy spirits, Paradise.
That these last ideas have been influenced by Christianity would seem to be sufficiently clear. Nor do we find a trace of Syria, India, and Paradise as soon as we leave this saga and pass to the others, in the chain of which it forms one of the later links. All the rest agree in transferring to the uttermost North the land which must be reached before the journey can be continued to the Glittering Plains and Odainsaker. Hervor's saga says that the Glittering Plains and Odainsaker are situated north of Halogaland, in Jotunheim; Herrod's and Bose's saga states that they are situated in the vicinity of Bjarmaland. The saga of Thorstein Bæarmagn says that they are a kingdom subject to Geirrod in Jotunheim. Gorm's saga in Saxo says it is necessary to sail past Halogaland north to a Bjarmia ulterior in order to get to the kingdoms of Gudmund and Geirrod. The saga of Helge Thoreson makes its hero meet the daughters of Gudmund, the ruler of the Glittering Plains, after a voyage to Finmarken. Hadding's saga in Saxo makes the Danish king pay a visit to the unknown but wintry cold land of the "Nitherians," when he is invited to make a journey to the lower world. Thus the older and common view was that he who made the attempt to visit the Glittering Plains and Odainsaker must first penetrate the regions of the uttermost North, known only by hearsay.
Those of the sagas which give us more definite local descriptions in addition to this geographical information all agree that the region which forms, as it were, a foreground to the Glittering Plains and Odainsaker is a land over which the darkness of night broods. As just indicated, Erik Vidforle's saga claims that the stars there are visible all day long. Gorm's saga in Saxo makes the Danish adventurers leave sun and stars behind to continue the journey sub Chao. Darkness, fogs, and mists envelop Hadding before he gets sight of the splendidly-clad proceres who dwell down there, and the shining meadows whose flowers are never visited by winter. The Frisian saga in Adam of Bremen also speaks of a gloom which must be penetrated ere one reaches the land where rich giants dwell in subterranean caverns.
Through this darkness one comes, according to the saga of Erik Vidforle, to a plain full of flowers, delicious fragrances, rivers of honey (a Biblical idea, but see Nos. 89, 123), and perpetual light. A river separates this plain from the land of the spirits.
Through the same darkness, according to Gorm's saga, one comes to Gudmund's Glittering Plains, where there is a pleasure-farm bearing delicious fruits, while in that Bjarmaland whence the Glittering Plains can be reached reign eternal winter and cold. A river separates the Glittering Plains from two or more other domains, of which at least one is the home of departed souls. There is a bridge of gold across the river to another region, "which separates that which is mortal from the superhuman," and on whose soil a mortal being must not set his foot. Further on one can pass in a boat across the river to a land which is the place of punishment for the damned and a resort of ghosts.
