There is genius in the little book. Its author perhaps did better than he meant, for he brings on every page the moral atmosphere of the underworld, the old folk-morality, the same in sixteenth-century Spain as in the oldest tales of sagacity and cunning. Lazarillo's shameless mother apprentices him to a blind beggar who promises to treat him like a son and begins his education at once. He takes the boy to a big stone on the outskirts of the town, and bids him listen to the noise within it. The boy puts his head close to the stone to hear the better, and the old rascal gives him a thundering blow, which, the stone being an admirable anvil, nearly cracks his skull. That is his first lesson ... never to be unsuspicious ... and it is as characteristic of the others as of _Reynard the Fox_. There never was so excellent a beggar as Lazarillo's master; no trick of the trade was unknown to him. As a fortune-teller, he could prophesy what his victims wished to hear. As a doctor he had his remedies for toothache, and for fainting-fits; not an illness could be mentioned but he had a physic ready to his hands. Then too, 'he knew by heart more prayers than all the blind men of Spain. He recited them very distinctly, in a low tone, grave and clear, calling the attention of the whole church; he accompanied them with a posture humble and devout, without gesticulations or grimaces of mouth, after the manner of those blind men who have not been properly brought up.' Indeed his only fault was avarice. 'He was not content with making me die of hunger,' says his pupil; 'he was doing the same himself.'
