Which culture matches these ideas: assimilation of Greek and Etruscan ideas, and pioneers in the round arch and vault, plus the use of concrete?

• A. Roman
• B. Greek
• C. Egyptian
• D. Persian

Answer: (A)

Roman architecture blends Greek ideas with Etruscan engineering, and it pioneered the round arch, the vault, and the use of concrete. The Romans adopted Greek decorative orders and classical proportions, but they transformed engineering possibilities by mastering the arch and vault, which let them span large spaces and create complex interior volumes. Concrete, used in vast quantities, gave them a versatile, durable material that enabled monumental buildings like baths, bridges, and the Pantheon. This combination—arch and vault built with concrete, built on Greek-inspired form but expanded by Etruscan influence—defines the culture described. Greek architecture relies more on post-and-lintel with columned orders, while Egyptian and Persian traditions do not feature these Roman arch-and-concrete innovations to the same extent.
