[Maédhros]

2) The next one is right after that on p.15, where Fingolfin says to Morgoth, "Come forth, thou coward king, to fight with thine own hand! Den dweller, wielder of thralls, liar and lurker, foe of Gods and Elves, come! For I would see thy craven face." [Since he uses the word "Gods" I assume it is one of the earlier versions of the story].

From The Grey Annals

§155 Now Fingolfin, King of the Noldor, beheld (as him seemed) the utter ruin of his people, and the defeat beyond redress of all their houses, and he was filled with wrath and despair. Therefore he did on his silver arms, and took his white helm, and his sword Ringil, and his blue shield set with a star of crystal, and mounting upon Rochallor his great steed he rode forth alone and none might restrain him. And he passed over the Anfauglith like a wind amid the dust, and all that beheld his onset fled in amaze, deeming that Oromë himself was come, for a great madness of ire was upon him, so that his eyes shone like the eyes of the Valar. Thus he came alone to Angband's gate and smote upon it once again, and sounding a challenge upon his silver horn he called Morgoth himself to come forth to combat, crying: 'Come forth, thou coward king, to fight with thine own hand! Den-dweller, wielder of thralls, liar and lurker, foe of Gods and Elves, come! For I would see thy craven face.'

5) On p.280, third full paragraph, CT says that he has "said elsewhere" of his father that, "with the completion of the the great 'intrusion' and departure of The Lord of the Rings, it seems that he returned to the Elder Days with a desire to take up again the far more ample scale with which he had begun long before, in The Book of Lost Tales..." [The quote goes further on p.280].

From the War of the Jewels: The Later Quenta Silmarillion

In these versions my father was drawing on (while also of course continually developing and extending) long works that already existed in prose and verse, and in the Quenta Silmarillion he perfected that characteristic tone, melodious, grave, elegiac, burdened with a sense of loss and distance in time, which resides partly, as I believe, in the literary fact that he was drawing down into a brief compendious history what he could also see in far more detailed, immediate, and dramatic form. With the completion of the great 'intrusion' and departure of The Lord of the Rings, it seems that he returned to the Elder Days with a desire to take up again the far more ample scale with which he had begun long before, in The Book of Lost Tales. The completion of the Quenta Silmarillion remained an aim; but the 'great tales', vastly developed from their original forms, from which its later chapters should be derived were never achieved.
