Doctor and alchemist Johann Otto von Helbig (16541698) combined East Indian and European knowledge in his theoretical writings and alchemical practice. He garnered attention with his own natural philosophy and cosmology, which provided him with access to the princely courts. This edition of Helbig's letters and documents is a key resource for research into Early Modern alchemy at royal courts.
