Midgard is the middle world of Norse myth, the home of humans between the realms of frost and fire, with Asgard above it.
Ignatius Donnelly places the home of the Norse gods on Midgard:
He dwelt with the twelve Æsir, or gods, upon Asgard, the Norse Olympus, which arose out of Midgard, a land half-way between the regions of frost and fire (to wit, in a temperate climate).
The same chapter is on The God Odi, Woden, or Wotan, and on Asgard: Home of the Æsir and Donnelly's Norse Atlantis I follow the home of the gods that rose above Midgard.
On The Secret of Plato's Atlantis (1885) Arundell answers that the burden is on Donnelly to show that Meru, Olympos, Elysium, Asgard and Midgard centred on Atlantis.
On Ymir and the creation of the world the gods create Midgard, the world of humans, and use an eyebrow of Ymir for its protective barrier.
On The Olympian Gods the war of the Æsir, led by Odin, against the older giants ends in the creation of Midgard, a world inhabited by gods and humans.
On Ancient wars Thor battles frost and fire giants to protect Asgard and Midgard, and on Thor (Etherean God) the Thor of Oahspe is compared with that Norse defender.
On Ragnarok: The Age of Fire and Gravel (1883) Donnelly reads the Midgard serpent as a comet whose approach sends the sea over the earth.

Thor often battled frost and fire giants to protect Asgard and Midgard.
The Oahspe Thor’s leadership and divine authority echo the Norse Thor’s role as a heroic defender of Asgard and Midgard.
He dwelt with the twelve Æsir, or gods, upon Asgard, the Norse Olympus, which arose out of Midgard, a land half-way between the regions of frost and fire (to wit, in a temperate climate).
Result: The creation of Midgard (Earth) and the establishment of a world inhabited by gods and humans, governed by a more structured pantheon.
He dwelt with the twelve Æsir, or gods, upon Asgard, the Norse Olympus, which arose out of Midgard, a land half-way between the regions of frost and fire (to wit, in a temperate climate).
Midgard, in Donnelly’s wording, is the land halfway between frost and fire, a temperate middle world from which Asgard arises.
