A good example of the old knowledge is The Garden of Health (Hortus sanitatis), an encyclopedia of natural history in which species of plants and animals are described along with modes of preparation for their medical application. Originally published in German, our copy is one of the many editions of the Latin translation. This treatise reflects the widely spread anxiety to compile an eclectic range of old written sources, including Graeco-Roman mythology, classical authors, and medieval bestiaries.
