Enya - willows on the water, 1997

"In Greek mythology Aiglé was one of the Hespéridés, who were guardians to the tree that bore apples of gold. When the Minyans approached them, imploring them to reveal a river so that they could quench their thirst, the Hespéridés metamorphosed into trees, Aiglé becoming a willow. She was the one to show the Minyans where to find water."
