First person view is the view point of the character writing or speaking directly about themselves. Third person view is the author or narrator telling the story. One advantage for First person would be that you can hear or read the thoughts the characters or having. A disadvantage in third person view is you can't know what the characters are thinking only their actions and what they say.
Answer: The figurative language describes the violence of the scene.
In this excerpt of <em>Pyramus and Thisbe</em>, Ovid uses very vivid imagery. He describes the blood flowing out of the body as if it was a broken leaden pipe. The blood was coming out in a long and hissing stream as jets of water. The figurative language used to describe this event helps us image the violence of the scene.
