We don't know who this first responsible for this shift. At any rate, the image of a radical and rapid transformation of society was behind it.In a letter that Erasmus wrote to Martin Bucer in 1527, he spoke bitterly of the violent turn taken by the Lutheran Reformation. He observed that, first, the assent of princes and bishops should have been sought, and any kind of seditious activity avoided; moreover, a number of things, among them the Mass, should have been "changed without disorder." There are people today, he concluded, who no longer accept anything that has to do with tradition ("quod receptum est"),as if a new world could be brought into being virtually instantaneously ("quasi subito novus mundus condi posset") A slow and gradual transformation on the one hand, a rapid and violent upheaval (revolutionary, we'd call it) on the other : the contrast was distinct. But nothing having to do with geography was suggested by with the expression "notus mundus": the emphasis was rather the term "condere" used to indicate the foundation of cities.
