Roman architecture was both inventive and derivative. How is the Roman temple related to both Greek and Etruscan designs? What specific aspects are uniquely Roman?© BrainMass Inc. brainmass.com August 15, 2018, 2:27 pm ad1c9bdddf
Etruscan is pre-Roman, or early Roman, and is more crude than later Roman structures and styles.

Roman temples, while related to the Greek temple form in general design and use of the Classical orders, represent a very defined category of temple form. The distinctive elements of being raised on a podium, having a front staircase, and having the columns along the sides being attached or engaged (pseudo-peripteral) allow for the easy identification of a Roman temple.

GREEK: Post and lintel/marble. ROMAN: True arch (barrel/groin vaults)/concrete.
