A rare edition of Lemnius's most influential work, The secret miracle of nature.
 
Lemnius (1505 – 1568) was a Dutch physician and author who studied medicine under Rembert Dodoens, Konrad Gesner and Vesalius. He practised in Zierikzee (Zeeland) from 1527 onward. Devoted to and beloved by his patients, he courageously catered to both their physical and spiritual needs during several outbreaks of the plague.
 
He authored several medical books, the most influential being the present De Miraculis occultis naturae (The secret miracles of nature). First published in 1559 it went through numerous editions and was translated into several vernacular languages. Among the topics discussed are balneology, teratology, psychiatry and precious stones.
 
”It is a most heterogeneous collection, heterogeneously piled together, of notions on physiological, physical, medical, religious, and moral topics, with attempts to explain phenomena in nature which subsequent enquiry has shown do not exist at all. The collection is a very curious one, notwithstanding, and furnishes good instances of popular ideas about natural things current three hundred years ago” (Ferguson).
