In 1669 the Danish-born natural scientist Nicolaus Steno published his noted treatise The Prodromus of Nicolaus Steno’s Dissertation Concerning a Solid Body Enclosed by Process of Nature Within a Solid, a seminal work that laid the essential framework for the science of geology by showing in very simple fashion that the layered rocks of … One result of Werner’s approach to rock classification was that each unique lithology in a succession implied its own unique time of formation during the Noachian flood and a universal distribution.
In Italy, again in the Tuscan Hills in the vicinity of Florence, Giovanni Arduino, regarded by many as the father of Italian geology, proposed a four-component rock succession. With the publication of the Prodromus and the ensuing widespread dissemination of Steno’s ideas, other natural scientists of the latter part of the 17th and early 18th centuries applied them to their own work.
