Both the Renaissance and the Printing Press are dated to be around the 14th century. While the first Printing Press was in 1436 (Johannes Gutenberg), the Renaissance is also supposed to start around a similar time-frame. I suspect that both influenced the right of the other.
Is it true, that the Renaissance was influenced as scientific ideas were more easily propagated than they had been in the past? It would be interesting to know one way or the other!
