Dr. Rydberg has shown that the "Seven Sleepers" story is an old Northern
myth, alluded to here in its early pre-Christian form, and that with
this is mixed other incidents from voyages of Swipdag, the Teutonic
Odusseus.

"Thorkill's Second Voyage to Outgarth-Loke to get Knowledge".--(a)
Guthrum is troubled as to the immortality and fate of the soul, and the
reward of piety after death. To spite Thorkill, his enviers advised the
king to send him to consult Outgarth-Loke. He required of the king that
his enemies should be sent with him.

(b) In one well-stored and hide-defended ship they set out, reached
a sunless, starless land, without fuel; ate raw food and suffered. At
last, after many days, a fire was seen ashore. Thorkill, setting a jewel
at the mast-head to be able to regain his vessel easily, rows ashore to
get fire.

(c) In a filthy, snake-paved, stinking cavern he sees two horny-nebbed
giants, (2) making a fire. One of the giants offers to direct him to

Outgarth-Loke chained, huge and foul.

(h) Thorkill plucks a hair of his beard "as big as a cornel-wood spear."
The stench that arose was fearful; the demens and snakes fell upon the
invaders at once; only Thorkill and five of the crew, who had sheltered
themselves with hides against the virulent poison the demons and snakes
cast, which would take a head off at the neck if it fell upon it, got
back to their ship.

(i) By vow to the "God that made the world", and offerings, a good
voyage was made back, and Germany reached, where Thorkill became a
Christian. Only two of his men survived the effects of the poison and
stench, and he himself was scarred and spoilt in the face.
