What is the author's style in Brand by Henrik Ibsen?

Ibsen wrote his play as a verse drama, also known as a dramatic poem, a play that is composed entirely of lines of poetry. This more romantic, less realistic style of play is less common in modern drama. From the first conversation in the play, the exchange between Brand and the peasant man, it is evident that the play is a verse drama. The first sign is that the dialogue is arranged into lines, as opposed to paragraph style.
