Although Bacon mentioned the shape of the continents in his Novum Organum (1620), there was no reference to the so-called jig-saw fit of the west coast of Africa with the east coast of South America. Instead the similarities of both east coasts and both west coasts were noted. The beginnings of the concept of continental drift can therefore not be attributed to Bacon.
