Better than fines?

"For him that stealeth a book from this library, let it change into a serpent in his hand and rend him. Let him be struck by palsy & all his members blasted. Let him languish in pain, crying aloud for mercy, & let there be no surcease for his agony until he sink to dissolution. Let bookworms gnaw his entrails in token of the worm that dieth not, & when at last he goeth to his final punishment let the flames of hell consume him for ever & aye."
