トルストンのサガ

Sö 54

バイキングの息子、トルストンのサガ（Þorsteins saga Víkingssonar or The Saga of Thorstein, Viking's Son） は７世紀にあったとされる伝説で、「大胆なフリシオフ（Frithjof the Bold）」の父の物語である。物語はノルウェーとスウェーデン（ウララッカー（Ulleråker）などの場所）から始まって、インドなどのエキゾチックな場所まで続く。「トルストンのサガ」は有名なサガの一つではないが、それでも面白い物語である。「大胆なフリシオフのサガ（The Saga of Fridthjof the Bold（Friðþjófs saga ins frœkna））」の前の時代の話となる。

It has been compared to the runestone Sö 54 in Bjudby, Södermanland, Sweden, as it also mentions a prominent family, and it besides the father Víkingr names three sons with the same names, and there are also close correspondences with the other names.

In Sweden, Viking sires nine sons by a second wife. Thorsten (Thorstein, or Thor's Stone) is the oldest son of Viking. Viking befriends his worthy foe Njorfe, King of Upplands, in Norway, who also has nine sons. The two groups of sons are highly competitive against each other. In a brutal ball game, they beat and maim each other, breaking each other's arms. A son of Viking, near death, slays a son of Njorfe.

Viking scolds this son and sends him to an island in Lake Vänern. Two more sons go with him, including Thorsten. Viking tells Thorsten to wait quietly on the island until the danger is over. Njorfe's sons want revenge. They use magic to conjure a frost that freezes the lake and travel across it to attack the three sons of Viking. Two of Viking's sons survive: Thorsten and Thorer. Two of Njorfe's sons survive, including his eldest son, Jokul, a sorcerer. Njorfe's sons use magic to discover that Thorsten and Thorer are alive.

Viking sends his two sons to the court of Halfdan for safety. Jokul invades Sogn, kills the king, banishes the heir Beli, and places a curse on the king's daughter Ingeborg, causing her to take the shape of a hideous troll. Jokul stirs a tempest which shipwrecks Thorsten twice. Ingeborg (as a troll, under the name Skellinefja) rescues Thorsten and asks him to promise to marry her. With her help, Thorsten returns Beli to the throne of Sogn, and the curse leaves Ingeborg. Thorsten unites with Ingeborg. Fridthiof is their son.

Thorsten, Beli, and Angantyr retrieve Viking's stolen magic ship Ellida. Thorsten fights Sote, a ghost pirate in barow mound, to get the magic ring (forged by Voland). Thorsten, Beli, and Angantyr conquer the Orkney Islands.

Thorsten and his son Frithiof inherit the magic sword Angurvadel and the magic ship Ellida from Viking. Descendants of Thorstein appear in Friðþjófs saga ins frœkna, and in the Starkad section of Gautreks saga.
