Monime is a character in a tragedy of five acts called "Mithridate". The term "mithridate" has come to refer to any generally all-purpose antidote. The manufacture of antidotes called mithridate or theriac (English "treacle") continued into the nineteenth century. He mixed all the effective antidotes into a single one, "mithridatium" or mithridate. The libretto is by , after Giuseppe Parini's Italian translation of Jean Racine's play "Mithridate". Until as late as 1786, physicians in London could officially prescribe mithridate. Mithridate discovers Pharnace's love for Monime by spreading a false rumour of his own death.
