Note 10 — Chapter VI · Diabolic Possession and Modern Spiritism
Reading edition
Cf. Vergil Æneid, IV. 471-3:
Agamemnonius scænis agitatus Orestes armatam facibus matrem et serpentibus atris cum fugit, ultricesque sedent in limine Diræ. (Or as the Atridan matricide Runs frenzied o’er the scene, What time with snakes and torches plied He flees the murdered queen, While at the threshold of the gate The sister-fiends expectant wait.)
