A nightmare within nightmaresch. 19, 20
Antony is “the only angel to have been there and come back,” and calls it “a nightmare within nightmares, though dreadfully aware, even inside it, of its foreboding falsehood” (19). Leviathan “held the keys to his Tartarus prison” (20), and “Tartarus will celebrate this castration of the dark oceans” (19).
Note: placed in the ocean.
