Did You Know?
Ignoramus is the title of a farce by George Ruggle (1575-1622) that was first produced in 1615. The title character, whose name in Latin literally means "we do not know," is a lawyer who fancies himself to be quite shrewd but is actually foolish and ignorant. Ruggle may have been inspired in his choice of name for his character by a proceeding in the English judicial system. The term ignoramus was written on bills of indictment when the evidence presented seemed insufficient to justify prosecution. In these cases ignoramus indicated "we take no notice of (i.e., we do not recognize) this indictment." Such a reference would have been most appropriate for Ruggle's satire of the judiciary.
