"'Twas Sir Everard Digby's ill fate to suffer in the Powder plott [the plot to blow up the English Houses of Parliment in 1605, a crime for which Guy Fawkes was later executed]. When his heart was pluct out by the Executioner (who secundum formam, cryed, Here is the heart of a Traytor!) it is credibly reported, he replied, 'Thou liest!'"
[Needless to say, this tale may be apocryphal.]
