In the Urals there are mountains all around. One mountain is called Copper, and it has its own Mistress. For a bad person to meet her is woe, and for a good person it is not good enough. There was a boy in the village, his name was Danilka the underfed, an orphan. And he became an apprentice to the malachite master Prokopyich, the best at that time. This is how Danila grew up, learning to work with malachite. And when he carved a sleeve - a snake - from a whole stone, he was recognized as a master.
