C) a polytheistic mythology
Ancient Greek and Roman societies made sense of their world through a polytheistic mythology. Both civilizations believed in a pantheon of gods and goddesses who controlled various aspects of life and nature. These deities were believed to influence everything from natural phenomena to human emotions, and they played a significant role in the daily lives and rituals of the ancient Greeks and Romans. The mythology provided explanations for the origins of the world, human existence, and natural events, helping to give meaning and structure to their understanding of the world around them. It also influenced their religious practices, social norms, and cultural traditions.
