MEGERA. Megaera was one of the Furies or Erinyes, her sisters being Allecto and Tisiphone. Daughters of the Night, they lived in the Underworld, where Proserpina was their mistress (Met IV.451-454, 481-484; Aeneid VI.554-556, 570-572; RR 19835-19837).
The poet invokes the Erinyes and asks Megera, Alete, and Thesiphone to help him, Tr IV.22-24. [Alete: Herenus: Proserpina: Thesiphone]
Megera, the French variant, appears initially, Tr IV.24.
