The Golden Calf, Which the World Adores, and Desires / In Which Is Handled the Most Rare and Incomparable Wonder of Nature, in Transmuting Metals; viz. How the Intire Substance of Lead, Was in One Moment Transmuted in Gold-Obrizon, with an Exceeding Small Particle of the True Philosophick Stone

The author presents a first-person account of alchemical inquiry, claiming observation and execution of a transmutation that converts lead into gold using a minute transmutatory powder. He recounts experiments and conversations with an experienced practitioner, describes practical procedures and spagyric and physico‑artificial principles, and defends the possibility of a Philosophick Stone against skeptics. The text warns about fraud and expense in the trade, considers the art’s medicinal and metallurgical aims, and intersperses metaphysical reflections on nature, knowledge, and the responsibilities of those who pursue these secret processes.
