From where did the great wisdom and the amazing secrets of the world emerge?
We have a story from Nürnberg. Paul Creuz was an inhabitant here who knew an amazing magic. To fulfill some of his wishes, he used his miraculous magic spell. He placed a new table in his garden, covered that with a white cloth, placed two milk-bowls on it, and also two honey-bowls, two plates, and nine knives. Then he took a black hen and shredded it on a pan in which cabbage was being cooked. The blood dripped into the boiling food. An unimaginable dish was prepared.
Next morning he took one part of it left it on the table. In the evening he kept the rest of the cabbage on the table and began chanting a spell. Finishing the incantation, he ran towards a green tree and hid himself behind that. He saw two small mountain people emerging from the earth. They sat at the table, and ate the precious smoky dish that was left there.
After they finished, Paul came to them and asked some questions. They answered. His wish was fulfilled.
Paul Creuz practiced the same repeatedly. The little men became so familiar that they too visited him in the house quite often. But he needed to give them time to finish the food first. If he did not wait, they either did not show up or disappeared soon. He finally got their king to support him. One day after hearing his sincere chant, the little king of the dwarfs came alone in a red scarlet cloak, under which he had a book. After finishing dinner, he threw the book on the table and allowed the host to read it as long as he wanted.
Eventually humans earned knowledge of all valuable secrets and great wisdom from that host of dwarfs.
