O, know, my name is lost.
By treason’s tooth bare-gnawn and canker-bit.
Yet am I noble as the adversary
I come to cope withal.
– William Shakespeare
King Lear, Act 5, Scene 3. A challenger steps up to prove Edmund’s treachery through a trial by combat. He says that his name and title have been lost to a traitor, chewed away by treachery. But he is as noble as his opponent and ready to fight. The challenger is a disguised Edgar, who is not yet ready to reveal his identity.
