Our immense possessions in every kingdom of Europe, our high military fame, which brings within our circle the flower of chivalry from every Christian clime---these are dedicated to ends of which our pious founders little dreamed, and which are equally concealed from such weak spirits as embrace our Order on the ancient principles, and whose superstition makes them our passive tools. But I will not further withdraw the veil of our mysteries. That bugle-sound announces something which may require my presence. Think on what I have said.---Farewell!---I do not say forgive me the violence I have threatened, for it was necessary to the display of thy character. Gold can be only known by the application of the touchstone. I will soon return, and hold further conference with thee."
~Ivanhoe by Sir Walter Scott, Chapter 24
