Step-by-step explanation:
Greek and Roman cultures were both polytheistic, meaning they believed in multiple deities. In Greek culture, there was a large pantheon of gods with various responsibilities, personalities, and capabilities. The Greeks held rituals, ceremonies, and festivals throughout the year to worship and appease the gods through offerings and sacrifices. Similarly, Roman religion was multifaceted and based on the Greek pantheon, but adapted to Rome's culture and language. They also practiced animal sacrifice and sought the favor of their many gods.
