Key passages
“She was so pale and motionless that if it had not been for her flowing tears and her hair that moved in the breeze, he would have taken her for a marble statue.”
Andromeda was so still and pale that only her tears and wind-blown hair convinced Perseus she was alive, not a carved statue.
Highlights the dramatic contrast between Andromeda's helplessness and Perseus's active heroism.
“As an eagle, when from his lofty flight he sees a serpent basking in the sun, pounces upon him and seizes him by the neck to prevent him from turning his head round and using his fangs, so the youth darted down upon the back of the monster and plunged his sword into its shoulder.”
Like an eagle swooping on a sunning snake and gripping its neck to avoid its bite, Perseus dove onto the monster's back and stabbed its shoulder.
Epic simile comparing Perseus to an eagle emphasizes his speed, precision, and dominance over the monster.
“Cassiopeia is called 'the starred Aethiop queen' because after her death she was placed among the stars, forming the constellation of that name. Though she attained this honor, yet the Sea-Nymphs, her old enemies, prevailed so far as to cause her to be placed in that part of the heaven near the pole, where every night she is half the time held with her head downward, to give her a lesson of humility.”
Cassiopeia became a constellation, but the vengeful Sea-Nymphs ensured she spends half each night upside down near the pole as a lasting lesson in humility.
Explains the mythological origin of the Cassiopeia constellation and its perpetual punishment for her pride.
