In "Romeo and Juliet" Lord Capulet is of a choleric temperament. That is, he is 1)extremely quick to anger and (2) emotional change. For instance, when he first hears the citizens expressing frustration over the feuding and violence as they shout, "Down with the Capulets! Down with the Montagues!" (l.48) he demands his sword (he is dressed for battle) and is immediately ready to fight against his foe, Lord Montague, who tells him, "Thou villain Capulet,--Hold me not, let me go" (l.52) as Capulet flourishes his sword threateningly. (3)This bellicose nature of Capulet who is ready to "do battle" manifests itself later with Juliet when he threatens her after she refuses to marry Paris.
