   • 1605, Miguel de Cervantes, “Capítulo I”, in El ingenioso hidalgo Don Quijote de la Mancha, Primera parte:

     En resolución, él se enfrascó tanto en su letura, que se le pasaban las noches leyendo de claro en claro, y los días de turbio en turbio; y así, del poco dormir y del mucho leer, se le secó el celebro de manera que vino a perder el juicio.

     In short, he became so absorbed in his books that he spent his nights from sunset to sunrise, and his days from dawn to dark, poring over them; and what with little sleep and much reading his brains got so dry that he lost his wits.
