By the word “falls” (ἀποπτώσεις) Cyril evidently refers to the story of Hephæstus, or Vulcan, to which Milton alludes (Paradise Lost, I. 740):— “Men call’d him Mulciber, and how he fell From heaven they fabled, thrown by angry Jove Sheer o’er the crystal battlements:  from morn To noon he fell, from noon to dewy eve, A summer’s day.”
