An excellent text book. Gives three chapters to Northern mythology.

Carlyle, Thomas. The hero as divinity; Odin.
In his Heroes and hero-worship.
This essay is most interesting and inspiring to the story-teller
who is presenting Scandinavian mythology.

Mabie, H.W. Norse stories.

In this collection the rugged strength of the Norse tales
is modified by a style that polishes and a beauty which
(however delightful in reading), could have been present
only in a vague way in the original stories.

Most of the adaptations are based on this translation.

The Nibelungs; tr. from the German of F. Schmidt by G. Upton.
