Greek religion was a polytheistic belief system centered around a pantheon of gods and goddesses, such as Zeus, Hera, and Athena. These deities were believed to control various aspects of life and nature, and they were often worshipped through rituals, sacrifices, and festivals. Temples were built in their honor, and myths were told to explain their actions and relationships. The ancient Greeks also believed in the importance of oracles, such as the famous Oracle of Delphi, where priests would interpret messages from the gods. Religious practices were deeply intertwined with daily life, influencing everything from politics to art, and they played a crucial role in shaping Greek culture and identity.
