Ans for question one:
Johannes Gutenberg was the German goldsmith who invented the printing press in the mid-15th century. The printing press is considered one of the most significant inventions of the Middle ages and lead to the spread of new ideas. It helped in that time because people who had a lot of work on their hands had the printing press at their side to aid them.
Ans for question 2:
Costantine moved Rome to Byzantium for many reasons, and all were symbolic and practical.
- Byzantium was closer to the center of the empire making control easier.
- Rome had become a periphery and Diocletian's choice of Nicomedia in the East was difficult to defend
Hope I helped :P
