If that thy valour stand on sympathy, There is my gage, Aumerle, in gage to thine: By that fair sun which shows me where thou stand’st, I heard thee say, and vauntingly thou spakest it That thou wert cause of noble Gloucester’s death. If thou deny’st it twenty times, thou liest; And I will turn thy falsehood to thy heart, Where it was forged, with my rapier’s point.
If your courage depends on sympathy, Here’s my challenge, Aumerle, in exchange for yours: By that bright sun that shows me where you stand, I heard you say, and you said it proudly, That you were the cause of noble Gloucester’s death. If you deny it twenty times, you’re lying; And I’ll prove your lies on your heart, Where they were made, with the point of my sword.
Lord Fitzwater · Act 4, Scene 1
Lord Fitzwater throws down his glove and accuses Aumerle of engineering Gloucester's death, and swears he heard Aumerle boast of it. The line persists because it introduces the farcical proliferation of accusations and challenges that follow—in the parliament scene, honor becomes a kind of currency that loses value through inflation. Each new gage thrown down makes the claims seem less serious, not more.
