Thor ever foremost marches on;
The others follow the faint light
That from his brazen armour shone,
And shudder oft from cold and fright.
Through caverns drear they move on slow,
Which seem to lengthen as they go;
Pale shadows flit along; they hear
The rustling sound of waters near:
Now toads croak harsh, and owlets screech;
Now fogs arise, and vapours damp;
