The Graeae ("old women" or "gray ones"), were three sisters, one of several trinities of archaic goddesses in Greek mythology.
The Graeae were daughters of Phorcys, one aspect of the "old man of the sea," and Ceto, and thus were among the Phorcydes, all of which were archaic beings either of the sea or chthonic deities.
The Graeae took the form of three grey-haired old women, though poets might give them the euphemistic designation "beautiful." Their age was so great that a childhood for them was hardly conceivable.
