In Euripides' Orestes the Erinyes are for the first time "equated" with the Eumenides[24] (Εὐμενίδες, pl. of Εὐμενίς; literally "the gracious ones", but also translated as "Kindly Ones").[25] This is because it was considered unwise to mention them by name (for fear of attracting their attention), the ironic name is similar to how Hades, god of the dead is styled Pluton, or Pluto, "the Rich One".[3] Using euphemisms for the names of deities serves many religious purposes.
