Jan Hanuš Máchal, The Mythology of All Races/Volume 3 (1918)
“ A man who robs a fairy of her pinions will bind her to himself; but so soon as she has regained possession of them, she will disappear. The eyes of the Vily flash like lightning, and their voices are so fine and sweet that to hear them once is to remember them forever. Men are often fascinated by their beauty; he who once chances to see a Vila, will yearn for her from the depths of his soul, and his longing will kill him at last. The fairies like to ride horses and stags, and they have the power of transforming themselves into horses, wolves, snakes, falcons, or swans. ”
