The Delphic Sibyl was a prophetess associated with early religious practices in Ancient Greece and is said to have been venerated from before the Trojan Wars as an important oracle. At that time Delphi was a place of worship for Gaia, the mother goddess connected with fertility rituals that are thought to have existed throughout the ancient Mediterranean world. As needed to maintain the religious tradition, the role of sibyl would pass to another priestess at each site.
