Le Livre Sans Titre, which translates as The Book Without a Title, is an 1830 French illustrated book warning against the harmful effects of masturbation.
He was young, handsome; his mother’s fond hope… He corrupted himself! [and] soon he bore the grief of his error, old before his time… his back hunches… See his eyes once so pure, so brilliant; they are extinguished! A fiery band envelops them. Hideous dreams disturb his slumber…he cannot sleep… His hair, once so lovely, falls as if from old age;his scalp grows bald before his age… His chest collapses… he vomits blood… Pustules cover his entire body… He is terrible to behold! His entire body stiffens!… his limbs stop moving… At the age of 17, he expires, and in horrible torment.
