Mechanica Medicina Sacra: Biblical Vegetarianism in Philippe Hecquet’s Theological Medicine

In the early eighteenth century, the French Jansenist physician Philippe Hecquet began publishing prolifically on the benefits of what he called “meatless medicine,” calling for a “Catholic cook” to guide France’s physical, moral, and spiritual health. This paper analyzes Hecquet’s defense of vegetarianism as an early modern example of a distinct kind of Biblical medicine – what Hecquet termed “theological medicine” – in the context of his understanding of bodily mechanism, natural history, and Biblical literalism, in his Traité des dispenses du carême (1709) and La medecine théologique, ou la medecine créée (1733). I argue that vegetarianism was the first principle of Hecquet’s Biblical medicine, which he considered both a natural and revealed truth to be grasped and applied by the pious physician.
