In this scholarly yet accessible introduction to the history of Hermeticism and its mythical founder, Florian Ebeling provides a concise overview of the Corpus Hermeticum and other writings attributed to Hermes. He traces the impact of Christian and Muslim versions of the figure in medieval Europe, the power of Hermeticism and Paracelsian belief in Renaissance thought, the relationship to Pietism and to Freemasonry in early modern Europe, and the relationship to esotericism and semiotics in the modern world.
