A rare and most unusual allegorical map, in which physician George-Christoph Würtz (1756-1823) arranged differing herbal simples according to their natural “affinity,” that is, based on the degree to which each consisted more or less of air, earth, fire (“phlogiston”), or water. The simples are arranged secondarily according to their effects on the human body, in regions such as “Emetica,” “Diuretica,” and “Emollientia.”

The map illustrated Würtz’s 1778 work of similar title, in which he laid out his theory of affinities. Though the map has the appearance of a curiosity, the work earned him prominence in French and German medical circles, where he traveled widely and was well received.
