John Questebrune, a graduate of Dublin College, was domestic chaplain to the 6th Earl of Galway during the first half of the 18th century. The name Questebrune is listed among Huguenot refugees in England and Ireland.
John Questebrune's Short Introduction to Natural Philosophy, 1718-1720, is distinguished by the relatively equal weight given to discussions of the physical and the animal world. Beginning with a standard analysis of the elements, motion, the earth and solar system, working within the four elements of earth, water, air, and fire, Questebrune proceeds to a detailed description of medicinal plants, animals, the human body, diseases, and therapeutics.
Written in Kilkenny, Ireland, between 1718 and 1720, the manuscript was subsequently owned by William Hamilton of the Woodlands, an Irish-born Philadelphian who had dual interests in the natural sciences and the Irish community. The manuscript is embellished with decorative sketches opening each of the seven chapters, as well as pen and ink and watercolor illustrations depicting the terrestrial globe, the Ptolemaic and Copernican solar systems, the phases of the moon, and the human body in dissection.
Questebrune's lengthy chapter on the medicinal uses of plants focuses on the "severall vertues" of plants and their "medicinal vertues," with minor commentary on their cultivation, and particularly of coffee, tea, and chocolate. His treatment of animals is more eclectic, and less detailed, but includes a valuable discussion of reptiles.
Perhaps the most important part of the Questebrune volume is his extensive discussion of the human body and its relations. Making reference to Paracelsus and occult philosophy, Questebrune provides a verbal dissection of the body (with an illustration to accompany), an analysis of conception and reproduction, and a fascinating discussion of sympathetic theory. In his treatment of diseases he provides receipts for "l'ongent divin," a "magnetick arsenical preservative from all Contagions even the Plague," "wound water," and digestives.
