Interesting Fact:
Who was the owner of the head when it was still connected to the rest of the body? This mysterious figure is named Mimir. It is believed that Mimir comes from a race of giants, predating the gods during the creation of the world. Thus, he is older than the Aesir and Vanir, the two main races of gods. The Aesir represent—more or less—the authority over the sky, while the Vanir gods are primarily responsible for fertility and the earth, along with earthly desires. The exact nature of the relationship between these two groups of gods remains a topic of discussion among scholars, but one thing is certain: a war occurred between them.
After years of fighting, during which neither side could definitively defeat the other, a truce was reached. According to Heimskringla, the saga of kings, to maintain peace, hostages were exchanged. Mimir was sent to the Vanir along with Hoenir—the same one who, along with Odin and Lothur, created the first humans.
It was Hoenir who offered humans reason and a desire to act; he had a magnificent appearance, noble features, and a regal demeanor, which endeared him to the Vanir, who made him their leader. But in reality, he was indecisive and hesitant, making wise decisions only with Mimir's guidance. Without his support, Hoenir was unable to accomplish anything; when Mimir was absent, he could not respond to questions and merely grunted under his breath. When the Vanir realized that Hoenir was incapable of independent decision-making, they became furious. They believed the gods of Asgard had deceived them during the hostage exchange and decided, in their wrath, to kill… Mimir.
And so it happened. Once it was all over, the unfortunate man's head was packed into a bag and sent back to Odin. But wise Odin took the head, coated it with herbs—to prevent it from decaying—and sang incantations over it for many days. In this way, the head gained the power of speech and later revealed many secrets to Odin, providing him with valuable counsel.
