When Cardinal Richelieu desired Callot to design and engrave a set of
plates descriptive of the siege and fall of his native town, he promptly
refused; and when the Cardinal peremptorily insisted that he should do
it, he replied, "My Lord, if you continue to urge me, I will cut off the
thumb of my right hand before your face, for I never will consent to
perpetuate the calamity and disgrace of my sovereign and protector."
