`Are these magic cloaks? ' asked Pippin, looking at them with wonder.
`I do not know what you mean by that,' answered the leader of the Elves. `They are fair garments, and the web is good, for it was made in this land. They are elvish robes certainly, if that is what you mean. Leaf and branch, water and stone: they have the hue and beauty of all these things under the twilight of Lórien that we love; for we put the thought of all that we love into all that we make.

But as Thingol turned the hilt of Anglachel towards Beleg, Melian looked at the blade; and she said: 'There is malice in this sword. The dark heart of the smith still dwells in it. It will not love the hand it serves; neither will it abide with you long.'

Of Túrin Turambar, The Silmarillion

Beleg drew his sword Anglachel, and with it he cut the fetters that bound Túrin; but fate was that day more strong, for the blade slipped as he cut the shackles, and Túrin's foot was pricked. Then he was aroused into a sudden wakefulness of rage and fear, and seeing one bending over him with naked blade he leapt up with a great cry, believing that Orcs were come to torment him; and grappling with him in the darkness he seized Anglachel, and slew Beleg Cúthalion thinking him a foe.

Of Túrin Turambar, ibid

I have told you of and introduced him (to his great delight) to the 'Kalevala' the Finnish ballads.
Amongst other work I am trying to turn one of the stories -- which is really a very great story and most tragic -- into a short story somewhat on the lines of Morris' romances with chunks of poetry in between.....†

                       -------------------------

† Tolkien's reworking of one of the Kalevala stories, 'The Story of Kullervo', was never finished, but proved to be the germ of the story of Túrin Turambar in The Silmarillion. For Tolkien's account of this, see [Letter] no. 163.

The germ of my attempt to write legends of my own to fit my private languages was the tragic tale of the hapless Kullervo in the Finnish Kalevala. It remains a major matter in the legends of the First Age (which I hope to publish as The Silmarillion), though as 'The Children of Húrin' it is entirely changed except in the tragic ending.

Letter 257, (1964).

  Kullervo, Kalervo's offspring,
Grasped the sharpened sword he carried,          320
Looked upon the sword and turned it,
And he questioned it and asked it,
And he asked the sword's opinion,
If it was disposed to slay him,
To devour his guilty body,
And his evil blood to swallow.
   Understood the sword his meaning,
Understood the hero's question,
And it answered him as follows:
"Wherefore at thy heart's desire                 330
Should I not thy flesh devour,
And drink up thy blood so evil?
I who guiltless flesh have eaten,
Drank the blood of those who sinned not?"
   Kullervo, Kalervo's offspring,
With the very bluest stockings,
On the ground the haft set firmly,
On the heath the hilt pressed tightly,
Turned the point against his bosom,
And upon the point he threw him,                 340
Thus he found the death he sought for,
Cast himself into destruction.
  Even so the young man perished, 
Thus died Kullervo the hero,
Thus the hero's life was ended,
Perished thus the hapless hero.
   Then the aged Väinämöinen,
When he heard that he had perished,
And that Kullervo had fallen,
Spoke his mind in words that follow:             350
"Never, people, in the future,
Rear a child in crooked fashion,
Rocking them in stupid fashion,
Soothing them to sleep like strangers.
Children reared in crooked fashion, 
Boys thus rocked in stupid fashion,
Grow not up with understanding,
Nor attain to man's discretion,
Though they live till they are aged,
And in body well-developed."                     360

And it came to pass that the masons of the house of Finwë, quarrying in the hills after stone (for they delighted in the building of high towers), first discovered the earth-gems, and brought them forth in countless myriads; and they devised tools for the cutting and shaping of gems, and carved them in many forms. They hoarded them not, but gave them freely, and by their labour enriched all Valinor.

[...]
But Maeglin prospered and grew great among the Gondolindrim, praised by all, and high in the favour of Turgon; for if he would learn eagerly and swiftly all that he might, he had much also to teach. And he gathered about him all such as had the most bent to smithcraft and mining; and he sought in the Echoriath (which are the Encircling Mountains), and found rich lodes of ore of divers metals. Most he prized the hard iron of the mine of Anghabar in the north of the Echoriath, and thence he got a wealth of forged metal and of steel, so that the arms of the Gondolindrim were made ever stronger and more keen; and that stood them in good stead in the days to come.

Of Maeglin, ibid

290-5 [490-5] During this time Túrin dwelt in Nargothrond. Beleg's sword, wherewith he was slain, was reforged for Túrin; and Túrin rejected his former name, and he called himself Mormael†, Black Sword, but his sword he named Gurtholfin‡, Wand of Death....

† Mormael was later changed to Mormegil.
‡ Gurtholfin might have been related to Gorthol??

[...]There are other stories almost equally full in treatment, and equally independent and yet linked to the general history. There is the Children of Húrin, the tragic tale of Túrin Turambar and his sister Níniel - of which Túrin is the hero: a figure that might be said (by people who like that sort of thing, though it is not very useful) to be derived from elements in Sigurd the Volsung, Oedipus, and the Finnish Kullervo....

And Gwindor gave the sword Anglachel into his hands, and Túrin knew that it was heavy and strong and had great power; but its blade was black and dull and its edges blunt. Then Gwindor said: 'This is a strange blade, and unlike any that I have seen in Middle-earth. It mourns for Beleg even as you do. But be comforted; for I return to Nargothrond of the house of Finarfin, and you shall come with me, and be healed and renewed.'
[...]
The sword Anglachel was forged anew for him by cunning smiths of Nargothrond, and though ever black its edges shone with pale fire; and he named it Gurthang, Iron of Death.

Of Túrin Turambar, The Silmarillion

                       -------------------------

Now Túrin was made ready for the journey, and he bade farewell to his mother, and departed in secret with his two companions. But when they bade Túrin turn and look back upon the house of his father, then the anguish of parting smote him like a sword, and he cried: "Morwen, Morwen, when shall I see you again?" But Morwen standing on her threshold heard the echo of that cry in the wooded hills, and she clutched the post of the door so that her fingers were torn. This was the first of the sorrows of Túrin.
[...]
But Morwen would not depart from her house, for her heart was yet unchanged and her pride still high; moreover Nienor was a babe in arms. Therefore she dismissed the Elves of Doriath with her thanks, and gave them in gift the last small things of gold that remained to her, concealing her poverty; and she bade them take back to Thingol the Helm of Hador. But Túrin watched ever for the return of Thingol's messengers; and when they came back alone he fled into the woods and wept, for he knew of Melian's bidding and he had hoped that Morwen would come. This was the second sorrow of Túrin.[...]

Is the feud achieved  thy fathers chains
on the laid, or lessened  by this last evil?
Dream not that Morgoth  will mourn thy death
or thy dirges chant  the dread Glamhoth -
less would like them  thy living hatred
and vows of vengeance;  nor vain is courage,
though victory seldom  be valour's ending.

...nor vain is courage though victory seldom be valour's ending.

I would argue that Turin never falls, never gives in to Morgoth and is as courageous and defiant as his father all the way to the end, when he realizes that, bearing Morgoth's curse, he is ruinous to himself and to everyone he encounters and in the end, bravely, unfallen, he kills himself, unwilling to be a further instrument of Morgoth's evil. We see Hurin later come to the same conclusion about himself.

If Turin had faced the judgement of a jury of his peers he would have been quickly absolved of any crime (IMO) except - he had taken his sister to wife and impregnated her. We have already seen Idril's reaction to Maeglin's attraction. My guess is that Turin's peers would have shunned him for his unwitting incest, his only happiness turned repugnant. That was what caused him to finally judge himself better dead.

I suspect JRRT ceased to enumerate them because there are so many... However it is surprising that the list does not begin with the loss of his sister Urwen (Lalaith).

Thank you for pointing that out; it's too bad that Tolkien never finished this . I also wonder why Tolkien didn't consider the death of Urwen (Lalaith) a sorrow of Túrin (as you mentioned). Maybe he just forgot to include it in his list.
