"He can perform a thousand things, and is the heart of all. He can perfect metals and minerals, impart understanding to animals, produce flowers in herbs and trees, corrupt and perfect air; in short, he produces all the odours and paints all the colors of the world. ...Know friend, that sulphur is the virtue of the world. And though Nature's second-born, yet the oldest of all things. To those who know him, however, he is as obedient as a little child. He is most easily recognized by the vital spirit in animals, the colour in metals, the odour in plants. Without his help his mother can do nothing."
