"Look, here it is, the prophetic Russian stone! O crafty Siberian. It was always green as hope and only toward evening was it suffused with blood. It was that way from the beginning of the world, but it concealed itself for a long time, lay hidden in the earth, and permitted itself to be found only on the day when Tsar Alexander was declared of age, when a great sorcerer had come to Siberia to find the stone, a magician."
Leskov Nikolai Semyonovich. Alexandrite.1884
