In short, our gentleman became so caught up in reading that he spent his nights reading from dusk till dawn and his days reading from sunrise to sunset, and so with too little sleep and too much reading his brains dried up, causing him to lose his mind. His fantasy filled with everything he had read in his books, enchantments as well as combats, battles, challenges, wounds, courtings, loves, torments, and other impossible foolishness, and he became so convinced in his imagination of the truth of all the countless grandiloquent and false inventions he read that for him no history in the world was truer.
