Greek religion evolved from Bronze Age traditions, incorporating animism and nature deities. The pantheon developed over time, with the Twelve Olympians emerging as main deities during the Archaic period. Homeric epics played a significant role in shaping mythology and beliefs. Greek religion was polytheistic, with gods representing aspects of nature and human emotions. Sanctuaries and temples served as centers of worship and community gatherings. Rituals, sacrifices, and festivals were central to religious practice, fostering a sense of shared identity among Greek city-states.
