Excerpt from The Firebird and Princess Vasilisa (http://www.widesky.org/stories_poetry/fire.html)
One day the huntsman went on his valiant horse to hunt in the woods. He rode and rode along the broad path, and suddenly he came upon a golden feather of the Firebird; it shone bright as a flame! The valiant horse said to him: "Take not the golden feather; if you take it, you will know trouble!"
