Myths of the Norsemen From the Eddas and Sagas
Northern cosmogony was not unlike the Greek, for the people imagined that the earth, Mana-heim, was entirely surrounded by the sea, at the bottom of which lay coiled the huge Midgard snake, biting its own tail; and it was perfectly natural that, viewing the storm-lashed waves which beat against their shores, they should imagine these to be caused by his convulsive writhing. The Greeks, who also fancied the earth was round and compassed by a mighty river called Oceanus, described it as flowing with “a steady, equable current,” for they generally gazed out upon calm and sunlit seas. Nifl-heim, the Northern region of perpetual cold and mist, had its exact counterpart in the land north of the Hyperboreans, where feathers (snow) continually hovered in the air, and where Hercules drove the Ceryneian stag into a snowdrift ere he could seize and bind it fast.
The Phenomena of the Sky
Like the Greeks, the Northern races believed that the earth was created first, and that the vaulted heavens were made afterwards to overshadow it entirely. They also imagined that the sun and moon were daily driven across the sky in chariots drawn by fiery steeds. Sol, the sun maiden, therefore corresponded to Helios, Hyperion, Phœbus, or Apollo, while Mani, the Moon (owing to a peculiarity of Northern grammar, which makes the sun feminine and the moon masculine), was the exact counterpart of Phœbe, Diana, or Cynthia.
The Northern scalds, who thought that they descried the prancing forms of white-maned steeds in the flying clouds, and the glitter of spears in the flashing light of the aurora borealis, said that the Valkyrs, or battle maidens, galloped across the sky, while the Greeks saw in the same natural phenomena the white flocks of Apollo guarded by Phaetusa and Lampetia.
As the dew fell from the clouds, the Northern poets declared that it dropped from the manes of the Valkyrs’ steeds, while the Greeks, who observed that it generally sparkled longest in the thickets, identified it with Daphne and Procris, whose names are derived from the Sanskrit word which means “to sprinkle,” and who are slain by their lovers, Apollo and Cephalus, personifications of the sun.
The earth was considered in the North as well as in the South as a female divinity, the fostering mother of all things; and it was owing to climatic difference only that the mythology of the North, where people were daily obliged to conquer the right to live by a hand-to-hand struggle with Nature, should represent her as hard and frozen like Rinda, while the Greeks embodied her in the genial goddess Ceres. The Greeks believed that the cold winter winds swept down from the North, and the Northern races, in addition, added that they were produced by the winnowing of the wings of the great eagle Hræ-svelgr.
The dwarfs, or dark elves, bred in Ymir’s flesh, were like Pluto’s servants in that they never left their underground realm, where they, too, sought the precious metals, which they moulded into delicate ornaments such as Vulcan bestowed upon the gods, and into weapons which no one could either dint or mar. As for the light elves, who lived above ground and cared for plants, trees, and streams, they were evidently the Northern equivalents to the nymphs, dryads, oreades, and hamadryads, which peopled the woods, valleys, and fountains of ancient Greece.
Jupiter and Odin
Jupiter, like Odin, was the father of the gods, the god of victory, and a personification of the universe. Hlidskialf, Allfather’s lofty throne, was no less exalted than Olympus or Ida, whence the Thunderer could observe all that was taking place; and Odin’s invincible spear Gungnir was as terror-inspiring as the thunderbolts brandished by his Greek prototype. The Northern deities feasted continually upon mead and boar’s flesh, the drink and meat most suitable to the inhabitants of a Northern climate, while the gods of Olympus preferred the nectar and ambrosia which formed their only sustenance.
Twelve Æsir sat in Odin’s council hall to deliberate over the wisest measures for the government of the world and men, and an equal number of gods assembled on the cloudy peak of Mount Olympus for a similar purpose. The Golden Age in Greece was a period of idyllic happiness, amid ever-flowering groves and under balmy skies, while the Northern age of bliss was also a time when peace and innocence flourished on the earth, and when evil was as yet entirely unknown. 
The Creation of Man
Using the materials near at hand, the Greeks modelled their first images out of clay; hence they naturally imagined that Prometheus had made man out of that substance when called upon to fashion a creature inferior to the gods only. As the Northern statues were hewn out of wood, the Northern races inferred, as a matter of course, that Odin, Vili, and Ve (who here correspond to Prometheus, Epimetheus, and Minerva, the three Greek creators of man) made the first human couple, Ask and Embla, out of blocks of wood.
The goat Heidrun, which supplied the heavenly mead, is like Amalthea, Jupiter’s first nurse, and the busy, tell-tale Ratatosk is equivalent to the snow-white crow in the story of Coronis, which was turned black in punishment for its tattling. Jupiter’s eagle has its counterpart in the ravens Hugin and Munin, or in the wolves Geri and Freki, which are ever crouching at Odin’s feet.
Norns and Fates
The close resemblance between the Northern Orlog and the Greek Destiny, goddesses whose decrees the gods themselves were obliged to respect, and the equally powerful Norns and Mœræ, is too obvious to need pointing out, while the Vanas are counterparts of Neptune and the other ocean divinities. The great quarrel between the Vanas and the Æsir is merely another version of the dispute between Jupiter and Neptune for the supremacy of the world. Just as Jupiter forces his brother to yield to his authority, so the Æsir remain masters of all, but do not refuse to continue to share their power with their conquered foes, who thus become their allies and friends. 
Like Jupiter, Odin is always described as majestic and middle-aged, and both gods are regarded as the divine progenitors of royal races, for while the Heraclidæ claimed Jupiter as their father, the Inglings, Skioldings, etc., held that Odin was the founder of their families. The most solemn oaths were sworn by Odin’s spear as well as by Jupiter’s footstool, and both gods rejoice in a multitude of names, all descriptive of the various phases of their nature and worship.
Odin, like Jupiter, frequently visited the earth in disguise, to judge of the hospitable intentions of mankind, as in the story of Geirrod and Agnar, which resembles that of Philemon and Baucis. The aim was to encourage hospitality; therefore, in both stories, those who showed themselves humanely inclined are richly rewarded, and in the Northern myth the lesson is enforced by the punishment inflicted upon Geirrod, as the scalds believed in poetic justice and saw that it was carefully meted out.
The contest of wit between Odin and Vafthrudnir has its parallel in the musical rivalry of Apollo and Marsyas, or in the test of skill between Minerva and Arachne. Odin further resembled Apollo in that he, too, was god of eloquence and poetry, and could win all hearts by means of his divine voice; he was like Mercury in that he taught mortals the use of runes, while the Greek god introduced the alphabet.
