Both ancient rome and greece had similar views on religion. greece believed in the greek polytheistic gods while the romans believed in their own, yet similar gods. these beliefs influenced both roman and greek architecture in a similar fashion. Both the romans and the greeks made similar marble statues, many of which depicted gods or warriors. greek architecture was primarily comprised of columns and roman architecture had more arches, as seen in the parthenon and coliseum respectively. hope this answers your question.
