What term means 'eye' in Latin and refers to a circular opening in a dome?

• A. Oculus
• B. Rotunda
• C. Cristallo
• D. Benin Bronzes

Answer: (A)

An oculus is the architectural term for a circular opening at the top of a dome. It directly evokes an eye—Latin for eye is oculus—and its function is to let light (and sometimes a glimpse of the sky) into the space, much like how eyes let light into vision. A classic example is the Pantheon’s oculus in Rome, which creates dramatic illumination inside the dome. The other terms don’t describe this feature: a rotunda refers to the round building or hall itself, cristallo means crystal, and Benin Bronzes are a group of West African metal artworks. So the circular dome opening named for the eye is the oculus.
