In Greek mythology the Erinyes (Ἐρινύες, pl. of Ἐρινύς, Erinys; literally “the avengers”) from Greek ἐρίνειν ” pursue, persecute”—sometimes referred to as “infernal goddesses” (Greek χθόνιαι θεαί)— were female chthonic deities of vengeance. A formulaic oath in the Iliad 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”.
