¿Qué opina Lutero con respecto al papa de la iglesia católica y su actuar? *

Johann Gutenberg (1399-1468), was born in Mainz, Germany. Before the invention of the printing press, books and documents were produced by handwritten copies, most of the time by monks, resulting in a slow and arduous work. In the Middle Age in Europe woodcut was used, on a wooden board an artisan recorded the words or drawings that had to be reproduced. The work was very laborious and if some piece was worn or part of the content changed, the complete mold had to be repeated.

Gutenberg's merit was to perfect the existing printing techniques, he melted each of the letters of the alphabet separately into metal, and devised a system to put them one after the other and fasten them. In this way, the pages could be composed faster and the molds could be reused to compose others. To reproduce the drawings, the woodcut was still used and later they were painted by hand.
