Synopsis
Three groups of objects associated with the court of Rudolf II. and his Kunstkammer that are said to be made from a seven-fold alloy, called Electrum, are presented in this essay: divinatory mirrors, spirit-summoning bells, and talismanic medals. Originating in Paracelsian literature, the Electrum was a curious material that let the paths of alchemists and goldsmiths cross, demanded great technological skill, and promised power and knowledge to its bearer.
