For him that stealeth, or borroweth and returneth not,
this book from its owner, let it change into a serpent in his hand and rend him.
Let him be struck with palsy, and all his members blasted.
Let him languish in pain crying out for mercy, & let there be no surcease to his agony till he sing in dissolution.
Let bookworms gnaw his entrails … when at last he goeth to his final punishment, let the flames of Hell consume him forever.
Curse on book thieves
From the monastery of San Pedro
