Original version: “With love's light wings did I o'erperch these walls,”
Modern version: With love’s wings did I climb over the walls.
This is not an example of personification but of hyperbole because a personification would be an attribute of a personal nature or human characteristics to something non-human which is untrue. While a hyperbole is an exaggerated statements or claims not meant to be taken literally which can be seen when Romero says love gave him wings.
It connects to love because Romero talks about how their love gave him wings to go climb over the wall and reach Juliet.
