A nomadic horseback warring tribe invaded the land of the Vanir. These tribesmen were fierce and came, according to Snorri Sturlusson, from Asia, and were consequently called the Aesir. Having realised that foreign invaders infringed their tribal lands, the Vanir, who were normally peaceable, was not about to relinquish their native lands without a fight. Thus the Vanir warred with the Aesir in defence of their sacred homelands. However, surrounding the land of the Vanir lay the homes of the Giants, mutual enemies of both the Vanir and the Aesir.
Realising that their strength lay in unity, the Vanir and the Aesir sued for peace, hostages were exchanged and each tribal member sealed the truce by spitting into a kettle. The Vanir sent to the Aesir as hostages: Niordr and his children, Frey and Freyja. In return, the Aesir sent to the Vanir; Hoenir and Mimir. Mimir, we learn, was Odin’s uncle, and something of a sorcerer. Even at this stage in his development, Odin too, was a sorcerer to reckon with.
The spit from the kettle, containing the entire wisdom of the two great races was turned into a man whom the gods of the Aesir called Kvasir. Kvasir was extremely wise. He went forth into Middle Earth, teaching mankind and paving the way for Rig, who would come after him. Kvasir's knowledge was legendary so much so that the jealousy of two dwarves; Fiallar and Gallar, was aroused. They slew Kvasir for his blood, which they blended with honey and brewed into mead. This mead was called the Holy Mead or Mead of Inspiration (Odhroerir/Odh-ruh-rir). Any person drinking of the potion would become wise. Any wise person drinking a draught would become all wise. However, as with most gifts, there was a price to pay.
The murderous dwarf s were caught and punished, not for the death of Kvasir, but for the murder of a giant and his wife whom they had killed as well. The giant killed was called Gilling and it was his son Suttungr who punished the dwarfs. The price of the wergild (form of compensation) was the mead of inspiration that the dwarfs had deposited inside three vessels: Odhroerir (Inspiration), Son (Offering) and Boden (Expiation). Suttungr secured the mead under a mountain and set his daughter, Gunlod as a sentinel to ward over them. Now, Odin had two ravens called Huginn (Thought) and Muninn (Memory) who reported to him the fate of men on Middle earth. When Odin realised the fate of Kvasir, he left his lofty seat in Asgard, called Hlithskjolf, and set off in pursuit of the holy mead.
Eventually, Odin encountered nine peasant giants who were cutting hay for a farmer. The farmer, a giant called Baugi was Suttungr's brother. Odin tricked the peasant giant farm workers into a quarrel, which concluded with the deaths of all nine. He then applied to Baugi for their job. In payment for his work, Odin asked Baugi for access to Gunlod ' s chamber. Baugi was reluctant, but when faced with a lost harvest, he agreed. Odin succeeded in his task after which Baugi took him to the mountain. However, no opening presented itself to Odin and Baugi and so Odin produced a gimlet or awl called Rati. Odin asked Baugi to bore a hole through the rock into Gunlod ' s chamber. Rati, like Rig, was an alter ego for Heimdallr who was later rewarded by Odin for his help. Once inside the mountain, Odin seduced Gunlod and was granted one sip of the Holy mead.
Odin did not swallow the drink, however, and was able to drain the contents of all three containers. Aided by the power of flight, Odin escaped from the mountain back to Asgard but was hotly pursued by Suttungr. The Gods, however, were expecting Odin' s return and were able to destroy Suttungr with fire. Odin safely discharged the mead into three containers. Despite the truce between the Vanir and the Aesir, the Vanir became very suspicious of Mimir's magical abilities, and promptly killed him. Mimir's head was then returned to the Aesir where Odin, lamenting his loss, preserved his uncle's remains with herbs and spells.
The head thus became oracular, and Odin set the token up over one of the three magical wells on the world Ash tree called Yggdrasil.
In other versions of the story, Odin turns Mimir's skull into a vessel to store or drink the mead from. All the versions agree, however, that some of the mead ended up in the well or in a vessel next to the well. The three vessels are now called: Heiddraupnir (light dropper) which was Mimir's skull, head or well; Hoddrofnir (treasure opener) a horn; and Odhroerir (exciter of the heart) which was probably another horn since horns tended to be found in pairs whereas there could only be one skull. The three wells each belonged to the three Norns or Wyrd sisters.
The first sister was called Urdr (norn of the past), the second Verdandi (norn of the present) and Skuld (norn of the future). Despite the obvious similarity between the words skull and Skuld, the well of the future was where Odin installed Mimir's head and the mead of inspiration. Skuld means: "I have killed and shall make recompense", as both Kvasir and Mimir were unjustly slain. The head of Mimir was an oracular devise and as such is connected to the well of the future. When Odin eventually took up the Runes, we learn that they too had oracular powers. Is there a possible association with the norn of the future, Skuld? The stage is now set for us to see how Odin became wise, then all wise.
The Havamal tells how Odin hung on the World Tree around which the whole of Germanic Cosmology revolved, for nine days and nine nights. He was given neither food nor horn to drink and was wounded with a spear. On each of the nine nights, he visited one of the nine branches or rafters of the tree. On each branch hung one of the nine worlds and in each of the nine worlds; Odin found one of the nine runes. Exhausted but wise, Odin returned from his ordeal and visited the well of Mimir. At this point the Sigdrifosmol takes up the story. Odin stood by the well, which was close to the precipice that overlooks the Germanic netherworld, Hel. He wore a helmet on his head and held the sword Brimir in his hand. He pledged an eye to Mimir to be allowed to drink and to swallow the mead of inspiration.
The general belief was his left eye but the sagas do not specify. Odin hid his eye in the well and took a draught of the Holy Mead. Odin now became all wise, one work led him to another, and one Rune led to another. Odin now had eighteen runes developed from his existing nine and there can be little coincidence that after this episode the Havamal proceeds to describe eighteen rune charms (Harvamal vs .146-163), After his nuministic experience, Odin broke a branch off Yggdrasil or the tree of life and fashioned from it his famous spear shaft, Gungnir. Since Gungnir is elsewhere referred to as being an ashen spear, it is logical to conclude that the Tree of Life is an Ash tree and indeed it is called the World Ash in other sagas. This was not the first spear in the saga however.
Odin starts his torment by being impaled upon a spear whilst he was suspended in the tree. This spear would seem to compliment the other, one to start the ordeal and one received as token at the end.
