The Physica (Medicine),[1] also known as the Liber simplicis medicine (Book of Simple Medicine), is a 12th-century medical text by Hildegard of Bingen.
Hildegard of Bingen served as an infirmarian at her first monastery and was well-acquainted with various medical traditions.[2] What was subsequently given the conventional title of Physica, or Medicine, by Johannes Schott[3] is part of Hildegard's lost medical collection, the Subtilitatum diversarum naturarum creaturarum libri novem (Nine Books on the Subtleties of Different Kinds of Creatures),[4][1] written between 1151 and 1158.[1]
In 1222, Gebeno , prior of the Cistercian monastery at Eberbach, claimed in the foreword of his Speculum futurorum temporum (Mirror of Future Times; a compilation of prophecies by Hildegard) that she had written a "book of simple medicine" (librum simplicis medicine).[5] A decade later, the Physica (under the title of Liber simplicis medicine) was submitted to Rome as part of Hildegard's canonisation inquiry, alongside the Liber composite medicine (Book of Compound Medicine),[a] another entry in Hildegard's Subtilitatum.[7]
The Physica survives in at least nine manuscripts dating from as early as the thirteenth century, five of which contain the full text.[8]
The Physica comprises nine books on plants (230 chapters),[8] elements (63 chapters),[b][10] trees (63 chapters),[10] stones (26 chapters),[11] fish (37 chapters),[11] birds (72 chapters),[c][12] animals (45 chapters),[d][14] reptiles (18 chapters),[15] and metals (8 chapters).[15] Each chapter discusses the medicinal properties of an entity based on the ideas of hot, cold, wet, and dry.[3]
According to Lois N. Magner, the Physica was "probably the first book by a female author to discuss the elements and the therapeutic virtues of plants, animals, and metals", as well as the first book on natural history composed in Germany.[4]
