Duke Angelo is the ruler of Andalusia, and Roderick and Henriquez’s father.
An old man, he is making preparations for his death and his succession. Not a fool, he is as suspicious of Henriquez as he is fond of Roderick, but this does not imply that he does not love his younger son. He is a just and honorable man, if old-fashioned and having strong views about the rights of parents. His main concern is that there should be order in the world.
