Snorri Sturluson starts his epic history of the kings of Norway with Ynglinga saga, a euhemerized account of the Norse gods. Here Odin and the Æsir are men from Asia who gain power through their prowess in war and Odin's skills. But when Odin attacks the Vanir he bites off more than he can chew and peace is negotiated after the destructive and indecisive Æsir-Vanir War. Hostages are exchanged to seal the peace deal and the Vanir send Freyr and Njörðr to live with the Æsir. At this point the saga, like Lokasenna, mentions that incest was practised among the Vanir.
Þá er Njörðr var með Vönum, þá hafði hann átta systur sína, því at þat váru þar lög; váru þeirra börn Freyr ok Freyja. En þat var bannat með Ásum at byggja svá náit at frændsemi. Ynglinga saga 4, Schultz's edition |
While Njord was with the Vanaland people he had taken his own sister in marriage, for that was allowed by their law; and their children were Frey and Freya. But among the Asaland people it was forbidden to intermarry with such near relations. Ynglinga saga 4, Laing's translation |
Odin makes Njörðr and Freyr priests of sacrifices and they become influential leaders. Odin goes on to conquer the North and settles in Sweden where he rules as king, collects taxes, and maintains sacrifices. After Odin's death, Njörðr takes the throne. During his rule there is peace and good harvest and the Swedes come to believe that Njörðr controls these things. Eventually Njörðr falls ill and dies.
Freyr tók þá ríki eptir Njörð; var hann kallaðr dróttinn yfir Svíum ok tók skattgjafir af þeim; hann var vinsæll ok ársæll sem faðir hans. Freyr reisti at Uppsölum hof mikit, ok setti þar höfuðstað sinn; lagði þar til allar skyldir sínar, lönd ok lausa aura; þá hófst Uppsala auðr, ok hefir haldizt æ síðan. Á hans dögum hófst Fróða friðr, þá var ok ár um öll lönd; kendu Svíar þat Frey. Var hann því meir dýrkaðr en önnur goðin, sem á hans dögum varð landsfólkit auðgara en fyrr af friðinum ok ári. Gerðr Gýmis dóttir hét kona hans; sonr þeirra hét Fjölnir. Freyr hét Yngvi öðru nafni; Yngva nafn var lengi síðan haft í hans ætt fyrir tignarnafn, ok Ynglingar váru síðan kallaðir hans ættmenn. Freyr tók sótt; en er at honum leið sóttin, leituðu menn sér ráðs, ok létu fá menn til hans koma, en bjoggu haug mikinn, ok létu dyrr á ok 3 glugga. En er Freyr var dauðr, báru þeir hann leyniliga í hauginn, ok sögðu Svíum at hann lifði, ok varðveittu hann þar 3 vetr. En skatt öllum heltu þeir í hauginn, í einn glugg gullinu, en í annan silfrinu, í hinn þriðja eirpenningum. Þá hélzt ár ok friðr. Ynglinga saga 12, Schultz's edition |
Frey took the kingdom after Njord, and was called drot by the Swedes, and they paid taxes to him. He was, like his father, fortunate in friends and in good seasons. Frey built a great temple at Upsal, made it his chief seat, and gave it all his taxes, his land, and goods. Then began the Upsal domains, which have remained ever since. Then began in his days the Frode-peace; and then there were good seasons, in all the land, which the Swedes ascribed to Frey, so that he was more worshipped than the other gods, as the people became much richer in his days by reason of the peace and good seasons. His wife was called Gerd, daughter of Gymis, and their son was called Fjolne. Frey was called by another name, Yngve; and this name Yngve was considered long after in his race as a name of honour, so that his descendants have since been called Ynglinger. Frey fell into a sickness; and as his illness took the upper hand, his men took the plan of letting few approach him. In the meantime they raised a great mound, in which they placed a door with three holes in it. Now when Frey died they bore him secretly into the mound, but told the Swedes he was alive; and they kept watch over him for three years. They brought all the taxes into the mound, and through the one hole they put in the gold, through the other the silver, and through the third the copper money that was paid. Peace and good seasons continued. Ynglinga saga 12, Laing's translation |
Þá er allir Svíar vissu, at Freyr var dauðr, en hélzt ár ok friðr, þá trúðu þeir, at svá mundi vera, meðan Freyr væri á Svíþjóð, ok vildu eigi brenna hann, ok kölluðu hann veraldar goð ok blótuðu mest til árs ok friðar alla ævi síðan. Ynglinga saga 13, Schultz's edition |
When it became known to the Swedes that Frey was dead, and yet peace and good seasons continued, they believed that it must be so as long as Frey remained in Sweden; and therefore they would not burn his remains, but called him the god of this world, and afterwards offered continually blood-sacrifices to him, principally for peace and good seasons. Ynglinga saga 13, Laing's translation |
Freyr had a son named Fjölnir, who succeeds him as king and rules during the continuing period of peace and good seasons. Fjölnir's descendants are enumerated in Ynglingatal which describes the mythological kings of Sweden.
