The Graeae were the three sisters who shared one eye and one tooth in Greek mythology.
The Graeae were named Deino, Enyo, and Pemphredo in the best-known genealogical tradition. They were daughters of Phorcys and Ceto, making them related to the Gorgons. Their shared eye and tooth were passed from one sister to another, an unusual detail that distinguishes them from Medusa’s family.
In the Perseus story, the hero sought information from the Graeae about how to reach the Gorgons. Some retellings say he seized their shared eye or tooth and forced them to reveal what he needed before returning it.
The Graeae are not Gorgons themselves. Their name means “old women,” and they belong to a separate group of ancient female beings in the mythic family of Phorcys and Ceto.
