Siegfried vs Alberich

 "Thereto the kings so mighty, / them slew he both as well.
But into gravest danger / through Alberich he fell,
Who thought for his slain masters / vengeance to wreak straightway,
Until the mighty Siegfried / his wrath with strong arm did stay.

"Nor could prevail against him / the Dwarf, howe'er he tried.
E'en as two wild lions / they coursed the mountainside,
Where he the sightless mantle / from Alberich soon won.
Then Siegfried, knight undaunted, / held the treasure for his own.
