The word Sibyl (in English, /ˈsɪbəl/) comes (via Latin) from the Greek word σίβυλλα sibylla, meaning prophetess. The earliest oracular seeresses known as the sibyls of antiquity, "who admittedly are known only through legend" prophesied at certain holy sites, under the divine influence of a deity, originally— at Delphi and Pessinos— one of the chthonic deities. Later in antiquity, sibyls wandered from place to place.
