ERINYS Their parentage is much discussed, being held by some to be the daughters of Night, by others Earth and Darkness, while still others ascribe to them Kronos and Eurynome as their parents. The Erinys were attendants of Hades and Persephone, and lived at the entrance to the Underworld. Their first duty was to see to the punishment of those who had committed some crime in the world above, but had arrived at Hades without obtaining absolution from the gods. Sometimes this duty extended to the world of men, where the Erinys (also called Dirae, Furiae, Eumenides or Semnae) would pursue criminals, at the behest of Nemesis, permitting the fugitive no rest. An example of the above is the tale of Agamemnon's son, Orestes, who slew his mother, Klytaemnestra, in revenge for his father's death.
