Chastes and Keepers of Secrets

Sixteenth-century Italy was rich in books of “secrets.” Among these works, Giambattista della Porta’s Magia Naturalis stands out as one of the best models. These compilations consisted of recipes, formulations, and practical advice covering various subjects like natural philosophy, astrology, medicine, alchemy, cosmetics, cooking, and occultism. Dating back to the period before the printing press, the manuscript Experimenti is another remarkable work, revealing the great interest of Renaissance courts in collecting recipes and practical secrets. Its authorship is attributed to Caterina Sforza, the founder of the Grand Ducal dynasty of the Medici.
