Mother Earth  móðir Jörð, our beloved planet.
Svalinn is the shield to protect us or land and waters would burn up due to Sun‘s heat.

Svalinn as the ozone layer is a new theory by Guðrún.

Mundilfari (mandala) möndull jarðar is earth’s axis .
Hjúki og Bil are Jack and Jill, perhaps same as rahu ketu, केतु रहु (dragon‘s tail head)
Mother Earth is also Þórs móðir, mother to Þór.
We Heathen men see her as a deity. Heathens were mocked for that stupidity to see stones and earth as a living deity. But we simply love her.
