Eumenides in Wikipedia

In Greek mythology the Erinýes (Ἐρινύες, pl. of Ἐρινύς, Erinýs; literally "the angry ones") or Eumenídes (Εὐμενίδες, pl. of Εὐμενίς; literally "the gracious ones" but also translated as "Kind-hearted Ones" or "Kindly Ones") or Furies or Dirae in Roman mythology were female chthonic deities of vengeance or supernatural personifications of the anger of the dead. A formulaic oath in the Iliad (iii.278ff; xix.260ff) invokes them as "those who beneath the earth punish whosoever has sworn a false oath". Burkert suggests they are "an embodiment of the act of self-cursing contained in the oath".[1]...
