But Thor, intent his goal to reach,
Struggles across the frozen swamp.
At length the gloomy fogs of night
Became dispell’d by sudden light;
Though faint, it fail’d not to impart
Fresh vigour to the Asa’s heart.
Two torches burning blue anon
A lurid flick’ring gleam display;
While through the cloven rock the moon
Sends forth a pale and wizard ray.
