Question

Which of these best describes how Roman architects used engaged columns?

A) To counteract lateral thrust

B) To support vaults

C) To cover joints in the concrete

D) To create a non-structural layer of correct Greek details

Answer 1

Roman architects used engaged columns primarily as an ornamental feature to present a layer of correct Greek details, contributing to the aesthetics of their structures rather than playing a major structural role.

Thus, the correct option is D.

Step-by-step explanation:

The engaged columns in Roman architecture were primarily used to create a non-structural layer of correct Greek details.

These engaged columns, also known as half-columns, are embedded in a wall and are partly ornamental, partly structural, reflecting the influence of Greek architecture on Roman aesthetics.

Although engaged columns can serve to articulate the divisions within a building or a wall, they were not primarily used to support vaults, counteract lateral thrust, or cover joints in concrete.

Thus, the correct option is D.
