It would be a METAPHOR. a comparison is being made between "Madison" and "a gazelle". This is used as a means to emphasize the fact that she ran very fast when she crossed over the finish line.
In the excerpt from Ozymandias by Percy Shelley, the below lines show that art alone can last forever.
Half sunk, a shattered visage lies, whose frown, And wrinkled lip, and sneer of cold command.
Tell that its sculptor well those passions read Which yet survive, stamped on these lifeless things"
The above line is the one that makes us understand that art can last alone forever. Percy Shelley talks about the sculpture's face that lies shattered.
Still, it cannot be forgotten to mention that, the frown, the wrinkled lip and the sneer of the command the face has cannot be missed to be appreciated.
Having understood these passions well, the poet says that the sculptor's accurate and artistic depictions still lives.
Omg I feel you i was on Alice through the looking glass and i was so stuck nobody helped me but thats ok. Its crazy because i know your struggling because its so hard!
