In Greek mythology the Erinyes (Ερινύες) or Eumenides (or Furies in Roman mythology) were female personifications of vengeance. A formulaic oath in the Iliad (iii.278ff; xix.260ff) invokes them as "those who beneath the earth punish whoever has sworn a false oath." Burkert suggests they are "an embodiment of the act of self-cursing contained in the oath" (Burkert 1985 p 198). They were usually said to have been born from the blood of Ouranos when Cronus castrated him. According to a variant account, they issued from an even more primordial level—from Nyx, "Night". Their number is usually left indeterminate. Virgil, probably working from an Alexandrian source, recognized three: Alecto ("unceasing," who appeared in Virgil's Aeneid), Megaera ("grudging"), and Tisiphone ("avenging murder"). Dante followed Virgil in depicting the same three-charactered triptych of Erinyes. The heads of the Erinyes were wreathed with serpents (compare Gorgon), their eyes dripped with blood, and their whole appearance was horrific and appalling. Sometimes they had the wings of a bat or bird, or the body of a dog.

The Erinyes are the main subject of the comic book The Kindly Ones from comic book series Sandman.
