A rare edition collecting several of Bovio's polemic works defending Paracelsian medicine.
 
Bovio was a noble Veronese medical practitioner, alchemist, astrologist, supporter of Paracelsian theories, and, according to some of his contemporaries, an impostor.
 
In 1583 Bovio had published Flagello de’ Medici Rationali, a scathing pamphlet attacking learned medicine. The physician Donzellini (under the pseudonym of "Claudio Gelli") published a reaction titled Riposta ad un certo libro contra medici rationali (1584), calling Bovio an impostor. The present work includes Bovio's replies to Donzellini, including, with a separate title-page, Risposta dell'eccellente dottor Claudio Gelli.
 
Bovio's books were reprinted several times throughout the 17th century, testament to the popularity of the alchemical Paracelsian tradition.
