The German free cities were then animated with the new spirit which was to mould the great age of Germany, and result in Dürer and Luther. The growing weakness of the Empire had fostered independence and self-reliance in the citizens, while the increase of commerce, both on the north to the German Ocean, and on the south through Venice, had introduced the wants of a higher civilization, and afforded the means to satisfy them. Local pride, which showed itself in the rivalries and public works of the cities, made their enterprise and industry more active, and gave an added impulse to the rapid transformation of military and feudal into commercial and democratic life. In these cities, where the body of men interested in knowledge and with the means of acquiring it, became every year more numerous, the new presses sent forth books of all kinds--the religious and ascetic writings of the clergy, mediæval histories, chronicles and romances, travels, voyages, botanical, military, and scientific works, and sometimes the writings of classic authors; although, in distinction from Italy, Germany was at first devoted to the reproduction of mediæval rather than Greek and Latin literature. The books in Latin, the learned tongue, were usually without woodcuts; but those in the vulgar tongues, then becoming true languages, the development and fixing of which are one of the great debts of the modern world to printing, were copiously illustrated, in order to make them attractive to the popular taste.
