Never knew it was Polish. Well, the more you know.
As promised, one Alaska Native tale. Athabaskan, to be precise.
This is how Raven stole the Sun and Moon.
A long time ago, when the world was younger, there was Raven. Raven was smart, a clever mischief maker, who has watched over the world since he remade it from the great flood.
In the early days of the new world, there was no Sun, nor Moon, as they had been washed away by the great waves. The people were thankful, but could not survive without the light. They could not hunt, nor fish. When they went out to find wood to burn in their fires, they had to crawl around in the forest feeling with their hands until they found something which might be wood. Then they would bite it to make certain that it was indeed firewood.
Raven saw how the people lived, and promised them he would bring back the Sun and Moon. For you see, as he was so clever, he knew where they had gone. They were swept into the sea, and now held by a great sea chief. This chieftain found the light they gave to be beautiful, and so hung them in his great house. He also had a single daughter, young and beautiful, his pride and joy. Raven knew he would do anything for her. So, he devised a plan, should simply asking fail.
He went to the great sea chief, and asked for the Sun and Moon. The chieftain refused. "They fell into my sea! They belong to me!" Again Raven asked, pleading for the people of the land, yet still, the chieftain refused. Raven left, knowing he had no choice but to follow his other plan.
Raven watched how the sea chieftain's daughter would leave the sea for a small stream to collect fresh water every morning. Raven watched, until he knew where she would always travel, and when. At last, when ready, Raven turned himself into a small fish, and fell into the water. So small was he, the girl did not see him, and so consumed him when she drank the water. When inside, he turned himself into a baby, and made the girl pregnant.
Soon after, the sea chieftain's daughter gave birth to a beautiful child, who was truly Raven. The child aged rapidly, far faster then any human child. The chieftain was proud of his grandson, and would do anything he asked.
One day, the boy asked the chieftain, "May I play with those?" pointing towards the Sun and Moon.
The chieftain, who would do anything to please his grandson, smiled and said, "Of course! Just be careful, for they are fragile, and can easily break." The chieftain then handed the child the Sun and Moon.
As soon as he had the Sun and Moon in his hands, the boy turned back into Raven, who laughed as he flew to the sky. The chieftain screamed, as he watched his prized possessions fly away, and cursed Raven for his trickery.
Raven was pleased with how he tricked the sea chief. However, in his haste to fly away, the Sun was held lightly in Raven's beak, and eventually fell to the ground. Raven cried in dismay, as the Sun shattered into many pieces. He was relieved to see most of the Sun remained intact, and put the largest and brightest piece into the sky. The smaller pieces, Raven swept into his wings and scattered across the sky, making the stars. The people cheered, as light was brought back into the world. They promised forever, that they would never kill ravens, because of what Raven did for them.
However, Raven felt sorry for his trick he pulled on the sea chief and his daughter. In apology, Raven made it so the Sun and Moon would return to the sea once a day, though not at the same time, so there would always be light for the people on the land.
And so, that was how Raven stole the Sun and Moon.
