Question

Highlight examples of metaphor in yellow and hyperbole in pink Rule thou in peace, our father, and our lord! Midst the remembrance of thy favours past, The meanest peasants most admire the last. May George, belov'd by all the nations round, Live with heav'ns choicest constant blessings crown'd! –“To the King's Most Excellent Majesty,” Phillis Wheatley

Answer 1

METAPHORS
"Father" - the king is not really his subjects' father. He acts their protector and sovereign, which is traditionally a father's role in a family. Hence the metaphor.
"Meanest peasants" - I believe he doesn't refer to peasants in the literal sense. He probably wants to say that even the most spiteful people have to admire the king's actions.
"Heave'ns choicest constant blessings crown'd" - this crown of heavenly blessings is a metaphor of God's will and patronage.

HYPERBOLES
"Belov'd by all the nations round" - this is an exaggerated image of the king. Of course, it is impossible that all the nations love and admire him.
"Live with heav'ns choicest constant blessings crown'd!" - this is a metaphor and a hyperbole at the same time.

Answer 2

'beloved by all nations round' in pink
