Jean François Fernel (Latinized as Ioannes Fernelius; 1497 -- 1558) was a French physician who introduced the term "physiology" to describe the study of the body's function. His medical works included De naturali parte medicinae (1542), De vacuandi ratione (1545), De abditis rerum causis (1548) which included a chapter on angelology and demonology. What has been called his "crowning work", Universa Medicina, comprises three parts: the Physiologia (developed from the De naturali parte), the Pathologia, and the Therapeutice.
This late 16th century edition of the Therapeutice and De abditis rerum causis combines two of his most important works, and they are very well printed by Wechel.
The binding is age-toned but the spine bears the still-legible author and title in a large black Gothic script.
