Geoffrey Chaucer,
The Canon’s Yeoman’s Prologue
“ When we be where we shall practise our elvish craft, we seem wondrous wise, our terms be so clerkly and strange. I blow the fire till mine heart fainteth. Why should I tell all the proportions of the things which we work upon, as on five or six ounces of silver, or perchance some other quantity, and busy me to tell you the names of iron scales, of orpiments and burnt bones, that be ground full fine into powder? ”
