13. The Transition from the Spirit of the Ancient Mysteries to That of the Mediaeval Mysteries

But the genuine students and researchers, who made investigations with retorts to learn about Man and about the wide world of Nature, are none other than glorified Faustian characters in the early Middle Ages. They are all deeply conscious of one thing. They can all say: ‘When we experiment, then the Nature Spirits speak to us, the Spirits of the Earth, the Spirits of the Water, the Spirits of the Fire, the Spirits of the Air. We hear their whispered murmurs, we hear their strangely wandering sounds, beginning with a humming and growing ever into harmony and melody that again turns back upon itself, melody unfolding melody. We hear them when Nature processes take place, when we stand before a retort.’ In all piety of heart, they steeped themselves in the process that was taking place. For example in the very process of which we have spoken, where they experienced the metamorphosis of oxalic acid into formic acid, when they asked the question of the process, and the Nature Spirit gave the answer, then it was so that they could as it were make use of what the Nature Spirit gave for the inner being of man. For then the retort began to speak in colour. And they were able to feel how the Nature Spirits of the earthy and of the watery rise up from the oxalic acid and assert themselves, and how the whole passes over into a humming melody, into a harmonious shaping of melodies that then again turns back into itself. Such was their experience of the process that results in formic acid and carbonic acid.
