Roman arches may develop into ___________.

Roman arches may develop into ___________.

• A. Pillars
• B. Vaults
• C. Colonnades
• D. Domes

Answer: (B)

Arches extended along a space become vaults. In Roman architecture, the curved shape of an arch distributes weight to its supports, and when that form is continued to cover a space, it becomes a vault—such as a barrel vault that spans a long corridor or a groin vault formed by the intersection of two arches. This development lets builders cover larger areas with fewer columns, creating more expansive interiors. Pillars or columns are vertical supports, not the result of extending an arch. A colonnade is simply a row of columns, and a dome is a different ceiling form that can be supported by arches and vaults but isn’t the direct progression from a single arch.
