Greek religion was a polytheistic belief system centered around a pantheon of gods and goddesses, each with specific roles and attributes. Major deities included Zeus, the king of the gods; Hera, the goddess of marriage; and Athena, the goddess of wisdom. Worship often involved rituals, sacrifices, and festivals to honor these deities, reflecting the importance of divine favor in daily life. Temples, such as the Parthenon in Athens, served as places of worship and community gatherings. Greek religion also included various myths and legends that explained natural phenomena and human experiences, contributing to a rich cultural heritage that influenced art, literature, and philosophy.
