Once the world was still young. Odin sat on his throne where he could see over all three parts of the world. He made the green land that stretched out before his eyes. With the help of the other gods he had made men and women who lived on the earth.
The elves and the ugly dwarfs decided to help Odin in caring his children of the earth. All seem to be going well. Until Odin knew that the frost giants were only waiting for the chance to bring trouble to his children. They were the ones who brought cold and ice to the world and shook the earth in anger. They hated Odin and all the works of the gods.
Down from his throne, Odin climbed. Down the broad rainbow bridge, he strode and across the green earth till he came to one of the roots of the great evergreen tree. There, close by the tree, was a well full of clear water. Its surface was so still it was like a mirror. In it one could see pictures of things that had happened and things that were going to happen.
Beside the well sat an old man named Mimir which means "memory". No one, not even the great Odin, could see the pictures in the well unless he first drank some of its water. Only Mimir could give the magic drink. So, Odin asked Mimir to give him at least one sip in able for him to see the pictures in the well. "The price of one drink from this well is not cheap," the price of a drink must be a great sacrifice, Mimir said. Odin thought of his son, Balder, whom he loved most in the world. But Mimir had read Odin's thoughts. I am not asking for your son. I ask for one of your eyes, Mimir said. Odin plucked out one of his eyes and handed it to Mimir. Then, Mimir smiled and gave Odin a horn full of the waters of his well.
After Odin drank the water from the well, he knelt by the edge of the well and watched the pictures passing across its still and silent surface. When he stood up again, he sighed, for it was as Mimir had said. He had seen sorrow and death as well as joy. It was only the glorious promise at the end that gave him courage to go on.
So Odin, the great king of the gods, became one-eyed. If you can find Mimir's well, you will see Odin's blue eye resting at the bottom. It is there to remind men and women of the great sacrifice he made for them.
