"Although Alchemy has now fallen into contempt, and is even considered a thing of the past, the physician should not be influenced by such judgements. For many arts, such as astronomy, philosophy , and others, are also in disrepute. I am directing you, physicians, to alchemy for the preparation of the magnalia, for the production of the mysteria, for the preparation of the arcana, for the separation of the pure from the impure, to the end that you may obtain a flawless, pure remedy, God-given, perfect, and of certain efficacy, acheiving the highest degree of virtue and power. For it is not God's design that the remedies should exist for us, ready-made, boiled and salted, but that we should boil them ourselves, and it pleases Him that we boil them and learn in the process, that we train ourselves in this art and are not idle on earth, but labour in daily toil. For it is we who must pray for our daily bread, and if He grants it to us, it is only through our labour, our skill and preparation."
