Lore
Two brothers once lived side by side. The older was a hard-hearted, wealthy goldsmith; the younger was a good-natured but penniless broom maker who had twin boys.
One day the poor man brought home a marvel from the woods—a golden bird. First he had found a single feather, then a golden egg, and finally the bird itself, which the rich brother bought for a great deal of money. The goldsmith knew a secret: anyone who ate the bird’s heart and liver would find a gold coin under his pillow every morning. He ordered his wife to roast the bird. While it was cooking, the poor man’s twins wandered into the kitchen and nibbled the heart and liver that had fallen onto the pan. From that night on, each boy awoke to a shiny gold coin.
