Inventions of the Renaissance had a very big impact on people's life. In order to get more knowledge and to make real life more interesting and creative, people started to invent. There were many inventions of the Renaissance: telescope, compass, printing press, etc. But the most important technological advance of all was the development of printing, with movable metal type, about the mid-15th century in Germany. A German named Johannes Gutenberg invented the printing press in 1436. Printing press invention had a large impact on the value of the books, religion and reformation and education.
Before the invention of printing press, multiple copies of a manuscript had to be made by hand. Hand written books took months or years to hand print. This made books very expensive. Printing press made it possible to produce more copies in a few weeks than formerly could have been produced in a lifetime by hand.
This made books cheaper. With the printing press they could do thousands copies of books. According to the Encyclopedia Britannica, by 1500 the presses of Europe produced some six million books.
This reflects through the church. The Bible was the first book to be mass-produced. Two hundred copies of the two-volume Gutenberg Bible were printed; this information is presented on the web site www.historyguide.org/intellect/press.html. People could buy the Bible and they did not go to churches anymore. This leads to Reformation and new religions. People realized that they could prey and confess at their homes. People set up the rules when, where and how they can pray and confess. Hundreds of new religions started to form. Some of them where thinking that the church was not right and that is why Reformation occurred.
In the Middle Ages, the only educated people in Europe were church leaders.
