The in Finnish national book- The Kalevala the is a person maybe give a model to Tolkien when he make that story about Turin and her sister.In The Kalevala the is talk about Kullervo in poem 31-36 and here is a part from the poem 36:
He went a little distance, walked a little way; he came to that tract in the forest, got to that place where he had ravished the maiden, ruined his mother`s offspring. There the lovely grass was weeping, the loveliest clearing lamenting, the young herbs grieving, the heather blooms complaining yhe repe of the girl, the ruining of the mothers`s offspring. Nor had young grass sprung up, no heather bloom come out, grown up in the spot, in that evil place where he had ravished the girl, ruined his mother`s offspring. Kullervo, son of Kalervo, drew his sharp sword; he looks at it, turns it over, questions it, inquired of it. He asked the sword its wish, whether it wanted to eat guilty flesh, drink sinful blood. The sword knew the man`s mind, understood what the warrior said: it answered with these words: "Why should I not eat as I want, eat guilty flesh, drink sinful blood? I eat the flesh of an innocent person, drink the blood of a sinless one, too." Kullervo, son of Kalervo, blue-stockinged son of an old man, pushed the hilt into the field, pressed the butt into the heath, turned the point against his breast, stuck himself onto the point. On that he contrived his death, met his end.
That was the death of the young fellow, the death of the man Kullervo, at long last the end of the man, the death of the luckless one.
It certainly was. The Kalevala was one of Tolkien's inspirations for writing his legends to begin with. His original ambition was to do for England what Lonnrot had done for Finland, but unlike Lonnrot he had no existing body of traditional stories to work with so he made up his own. In the oldest versions of his stories, Tol Eressea, the Lonely Isle, was therefore a prehistoric and pre-human Britain, and in his original conception the city of Kortirion (later the city of Tirion upon Tuna) corresponded to Warwick.
He fell in love with the sound of Finnish, and although he never learned much of it he based the phonology of one of his Elvish languages Quenya on it. (But not the grammar or other features.)
Certain parts of the story of the Children of Hurin also correspond to the Volsung saga.
Hmm...I read somewhere that Tolkien loved Kalevala.Between the two mythologies really have much in common.In principle, this is not surprising that all myths are somewhat similar.The difference is only in national qualities,names and landscapes.
And so Doom comes for the Master of Doom, but it is delayed a while... Nice depiction of the event. IIRC it took place during a rainstorm, where Turin saw what he first thought was a ghost on the grave-mound, but you have done a nice job of a daylight encounter.
