In Chapter 11, Okonkwo and Ekwefi undergo a terrifying series of events, forced to observe as their only daughter Ezinma is summoned before the god Agbala in the middle of the night. Achebe uses a variety of figurative language, including paradox and simile, to set the mood:
Chielo ignored what [Okonkwo] was trying to say and went on shouting that Agbala wanted to see his daughter. Her voice was clear as metal, and Okonkwo's women and children heard from their huts all that she said.
In this excerpt Achebe utilizes simile as a device, comparing Chielo's voice to metal. Within this simile exists a seemingly paradoxical statement: the priestess's voice is as "clear as metal." Metal is generally not see-through—thus, it appears contradictory to describe the "metal" of Chielo's voice as "clear." Achebe uses this bit of figurative language to describe more than just the sonic quality of Chielo's voice. "Clear[ness]" encompasses intent and assertiveness, indicating Chielo's confidence, as well as the harshness of her voice. When inhabited by the spirit of Agbala, Chielo becomes a different person. In such a state, her "clearness" and harshness stem from her authority as a divine representative. Both qualities serve to intimidate those around her, making people like Okonkwo and Ekwefi, normally Chielo's friends, intimidated and frightened.
