Medical honoraria in the 17th century.

Paolo Zacchias (1584-1659), the physician of the Pope, in his main work, "Quaestiones medico-legales" (Rome, 1621-1625) provides answers to hundreds of important practical and theoretical questions. On the following pages the author tries to summarize Zacchias's opinion concerning the problem of honorarium and fee, hoping that this short extract will prove to be useful for the modern physician as well.
