“When the dragon awoke, new woe was kindled.
O’er the stone he snuffed. The stark-heart found
footprint of foe who so far had gone
in his hidden craft by the creature’s head. --
So may the undoomed easily flee
evils and exile, if only he gain
the grace of The Wielder! -- That warden of gold
o’er the ground went seeking, greedy to find
the man who wrought him such wrong in sleep.
Savage and burning, the barrow he circled
all without; nor was any there,
none in the waste.... Yet war he desired,
was eager for battle. The barrow he entered,
sought the cup, and discovered soon
that some one of mortals had searched his treasure,
his lordly gold. The guardian waited
ill-enduring till evening came;
boiling with wrath was the barrow’s keeper,
and fain with flame the foe to pay
for the dear cup’s loss.”
