The erinyes (singular: erinys) are Greek goddesses or spirits residing in the Underworld. They punish those who swear false oaths and those who commit heinous crimes. They are most well known for pursuing Orestes. They condemned his as a matricide, though he was avenging the death of his father Agamemnon. Orestes was later pardoned in the court of the gods. Their name means "avengers". In Roman mythology, they are known as the Furies, or Dirae.
