Reason of Martin Luther: 
In 1517, the religious reformer Martin Luther wrote Ninety Five Theses criticising many of the practices and rituals of the Roman Catholic Church. A printed copy of this was posted on a church door in Wittenberg. It challenged the Church to debate his ideas. Luther’s writings were immediately reproduced in vast numbers and read widely. This lead to a division within the Church and to the beginning of the Protestant Reformation. Luther’s translation of the New Testament sold 5,000 copies within a few weeks and a second edition appeared within three months. Deeply grateful to print, Luther said, ‘Printing is the ultimate gift of God and the greatest one.’

In the sixteenth century, Menocchio, a miller in Italy, began to read books that were available in his locality. He reinterpreted the message of the Bible and formulated a view of God and Creation that enraged the Roman Catholic Church. When the Roman Church began its inquisition to repress heretical ideas, Menocchio was hauled up twice and ultimately executed. The Roman Church, troubled by such effects of popular readings and questionings of faith, imposed severe controls over publishers and booksellers and began to maintain an Index of Prohibited Books from 1558.
