    • 1820, Percy Bysshe Shelley, Oedipus Tyrannus; Or, Swellfoot The Tyrant: A Tragedy in Two Acts:
      But my Leech—a leech
      Fit to suck blood, with lubricous round rings,
      Capaciously expatiative, which make
      His little body like a red balloon,
      As full of blood as that of hydrogene,
      Sucked from men’s hearts
