Magia Naturalis (in English, Natural Magic) is a work of popular science by Giambattista della Porta first published in Naples in 1558. Its popularity ensured it was republished in five Latin editions within ten years, with translations into Italian (1560), French, (1565) Dutch (1566) and English (1658) printed.
Natural Magic was revised and considerably expanded throughout the author's lifetime; its twenty books (Naples 1589) include observations upon geology, optics, medicines, poisons, cooking, metallurgy, magnetism, cosmetics, perfumes, gunpowder, and invisible writing.
Natural Magic is an example of pre-Baconian science. Its sources include the ancient learning of Pliny the Elder and Theophrastus as well as numerous scientific observations made by Della Porta.
