Where in the Friar Lawrence soliloquy is there a hyperbole?

Answer 1

I guess you mean the following passage:

• The grey-eyed morn smiles on the frowning night,
  Chequering the eastern clouds with streaks of light,
  And flecked darkness like a drunkard reels
  From forth day's path and Titan's fiery wheels:
  Now, ere the sun advance his burning eye,
  The day to cheer and night's dank dew to dry,
  I must up-fill this osier cage of ours
  With baleful weeds and precious-juiced flowers.
  The earth that's nature's mother is her tomb;
  What is her burying grave that is her womb,
  And from her womb children of divers kind
  We sucking on her natural bosom find,
  Many for many virtues excellent,
  None but for some and yet all different.
  O, mickle is the powerful grace that lies
  In herbs, plants, stones, and their true qualities:
  For nought so vile that on the earth doth live
  But to the earth some special good doth give,
  Nor aught so good but strain'd from that fair use
  Revolts from true birth, stumbling on abuse:
  Virtue itself turns vice, being misapplied;
  And vice sometimes by action dignified.
  Within the infant rind of this small flower
  Poison hath residence and medicine power:
  For this, being smelt, with that part cheers each part;
  Being tasted, slays all senses with the heart.
  Two such opposed kings encamp them still
  In man as well as herbs, grace and rude will;
  And where the worser is predominant,
  Full soon the canker death eats up that plant.

There are no hyperboles here. Personification: "grey-eyed morn", "frowning night", "his burning eye". Simile: "like a drunkard" Allusion: "Titan's fiery wheels" Metaphor: "Two such opposed kings" Extended Metaphor: "earth that's nature's mother" et seq. The whole speech may be summarized: "It is nearly dawn; I need to collect plants. The earth gives birth to many kinds of plants and all have some good use, but if they are misused they have bad effects. This flower here is good for you if smelled, but poison if eaten. Both good and bad are in people as well as plants, and if the bad is stronger, brings death."

In Friar Lawrence's soliloquy in Romeo and Juliet, the hyperbole can be found when he says, "The gray-eyed morn smiles on the frowning night." This is an exaggerated statement comparing morning to a person with eyes and emotions.
