Olympia's Confession

Found scratched into the wall in the basement of an estate in Pella.

  I shall surely die here, and perhaps for my crimes against P. A. I deserve 
  to. Let me at last confess, then, that the father was neither the one-eyed 
  beast, nor Zeus in the form of an oak, but a snake sent by Nectanebos of the 
  many faces. P. was fooled by the disguises, but I fancy I never was.
  
  Was his father a god in the form of a snake, then, or just a snake? Am I 
  Europa or Pasiphae? But we all know the monster born of unnatural union was 
  Kukuth, the one who killed Stratobia. Had she not, everything would have 
  been different. I would be mistress of the world, and not even N., clad as a 
  crone, would have been able to stop me. Surely had anything gone differently 
  I would not be here today with nothing but my snakes and the ghosts of those 
  I killed.
