Antonioundergoes adynamicchange (from sadness and melancholy to happiness).
He showsmercyto Shylock (IV, 1: 380-90). But Antonio has no big speeches at the end of play. In fact, as a title character, he speaks very little. The character of Portia actually dominates finalact.
Shylockis the most interesting character in the play. He is a highly developed character, although he is also stereotyped in some ways. His big speech on revenge (III, 1:53-
73) and his appearance in the courtroom scene (IV, 1: 35-62) are the central occasions when his character becomes fully illuminated. His demands for justice and his admission that revenge is unreasonable help to establish the portrayal of Shylock as one of Shakespeare’s most dramatic psychologicalcharacters.
