Material is lacking to prove the historical truth of the Teutonic traditions which point to Scandinavia as the cradle of the Teutonic tribes. But Jordanes, the first historian of Teutonic birth who speaks of Scandinavia, stands at the cradle of Swedish history, and, as a modern historian has expressed it, his shadow throws an umbrage across the whole field of Swedish historical research. The mistake, based upon Jordanes’ history, of identifying the Swedish Gauts with the Goths has caused a great deal of mischief and ridiculous chauvinism, Gothic and Swedish history and royal lines being mixed up or put in connection with each other.
In leaving aside the Teutonic traditions of the island of Scandza, or Scania, as the cradle of the race, let us quote a remark by Tacitus which seems to point to the conclusion that such traditions were current already in the first century of the Christian era: “I should think that the Teutons themselves are aborigines, and not at all mixed through immigrations or connections with non-Teutonic tribes. For those desiring to change homes did not in early times come by land, but in ships across the boundless and, so to speak, hostile ocean--a sea seldom visited by ships from the Roman world.”
The Old English poem of Beowulf must also be mentioned among the sources which throw light on early Swedish history. Whether the Geátas of Beowulf are identical with the Jutes of Denmark, or with the Gauts of Sweden, is a much disputed question. Although, phonetically, the Old English name Geátas corresponds to the Old Swedish _Gautar_, it seems most plausible to suppose that by this term is meant the Jutes, and not the inhabitants of Swedish West or East Gothland. This accepted, the poem does not contain much about the Swedes. But the information, therein given, of the Swedish kings is of great value, because it renders the service of a firm chronological support to the facts gathered from another source. This source, of vastly greater importance, is the Ynglinga Saga, or rather the poem around which it is spun, in Heimskringla, of which more in the next chapter.
The first information of the religion practiced by the inhabitants of Scandinavia is given by Prokopios, who says that they worshipped many gods and spirits of the sky, air, earth, sea, and also some who were supposed to dwell in springs and rivers. Offerings were constantly made, the chief ones being of human beings, for which the first prisoner made in a war was destined. This sacrifice was made to “Mars,” who was the highest god. The statements of Prokopios without doubt are correct. The Scandinavian war-god who corresponds to the Mars of classical mythology was Tyr. Odin, originally the ruler of the wind, became the highest god during the Viking Age. He is an aristocratic god, the god of the select few, whose cult succeeded that of Tyr as the cult of the latter had succeeded that of Thor, the thunderer, as the highest god. The idea of a supreme God was probably unknown until the contact with Christianity, or at least not common. Thor, the peasant god, is probably the oldest of the gods of Teutonic mythology, the representative of stern power and law-bound order. Thor was the most popular god of the Swedes, to judge from the great number of ancient Swedish proper names of which his forms a part. Besides Thor, Odin and Frey were the most honored. All the other gods and goddesses mentioned in Old Norse literature were probably known, but few of them much worshipped in Sweden.
