Chapter LX: Section III: Jormundgander, or the Midgard-Serpent

The Midgard- or world-serpent we have already become tolerably well acquainted with, and recognize in him the wild tumultuous sea. Thor contended with him; he got him on his hook, but did not succeed in killing him. We also remember how Thor tried to lift him in the form of a cat. The North abounds in stories about the sea-serpent, which a nothing but variations of the original myth of the Eddas. Odin cast him into the sea, where he shall remain until he is conquered by Thor in Ragnarok.
