The culture of ancient time both enriched other civilizations and was enriched by civilizations outside the Roman Empire mainly by what?

Trade, cultural exchanges, and the spread of ideas and technologies. The Roman Empire had extensive trade networks that brought goods, knowledge, and cultural influences from other civilizations, such as the Greeks, Egyptians, Persians, and Mesopotamians. Additionally, the Romans adopted and adapted many aspects of these other cultures, including art, architecture, language, religion, and philosophy, which enriched their own culture. In turn, the Roman Empire also spread its own culture and influence to the regions it conquered, leaving a lasting legacy on the development of Western civilization.
