Fingolfin like a shooting light
beneath a cloud, a stab of white,
sprang then aside, and Ringil drew
like ice that gleameth cold and blue,
his sword devised of elvish skill
to pierce the flesh with deadly chill.
With seven wounds it rent his foe,
and seven mighty cries of woe
rang in the mountains, and the earth quook,
and Angband's trembling armies shook.
