 Probably due to early influences from his father Diotifeci, who was a doctor to Cosimo de' Medici, Ficino published Latin and Italian treatises on medical subjects such as "Consiglio contro la pestilenza" (Recommendations for the treatment of the plague) and "De vita libri tres" (Three books on life).His medical works exerted considerable influence on Renaissance physicians such as Paracelsus, with whom he shared the perception on the unity of the micro- and macrocosmos, and their interactions, through somatic and psychological manifestations, with the aim to investigate their signatures to cure diseases.Those works, which were very popular at the time, dealt with astrological and alchemical concepts.
