The grave, where the playwright was buried in 1616, carries the warning: "Good friend, for Jesus' sake forebeare, To digg the dust enclosed heare; Bleste be the man that spares thes stones, And curst be he that moves my bones."
I would say that Shakespeare uses allusion in this excerpt from Romeo and Juliet. He is alluding, or making a reference to Aurora, who is a character/person outside of Romeo and Juliet.
