I'll drown more sailors than the mermaid shall; I'll slay more gazers than the basalisks; I'll play the orator as well as Nestor, Decieve more slily that Ulysses could, And like a Sinon, take another Troy. I can add colors to the chameleon, Change shapes with Proteus for advantages And set the murderous Machiavel to school. Can I do this, and cannot get a crown? Tut! were it further off, I'll pluck it down.
