Far away in the mists of ancient days, there once dwelt a band of extraordinary trees with the gift of prophecy: oaks with the power of human speech, answering the needs of mortals who journeyed far to seek their wise counsel. This sounds like a folk tale, but it is not. Deeply rooted in archaic Greek myth, these oaks also lived in history as the first and only oracle existing in Greece for many years. Ancient mythographers remembered the priestesses who tended these oaks as the first females on earth who ever sang their own compositions; their companion nymphs were compassionate nurses for Zeus, shielding him in his vulnerable infancy, and henceforth revealing his will to mortals. In the remote and mountainous terrain of Epirus in northwest Greece, from the second millennium BCE, this sacred forest grew in the mystical sanctuary of Dodona.
