Historic documentation of continental drif

Papers & Reports

Summary

The concept of continental drift started with the Ancient Greeks. Translation of part of Strabo’s Ancient Greek manuscript based on Eratosthenes’ mapping of sub-continental scale, geographic and geologic units which he named ‘sealstones’, led to the discovery that he had employed a successful, rectangular co-ordinate, mapping method. As early as c.240–220 BCE the detail of his data produced the first evidence of the continental drift of Italy from Corsica/Sardinia. Some 22 centuries later, Professor SW Carey convened an international symposium in Hobart in 1956 where he presented a global, hemispheric projection and included more detail of the same Mediterranean area. These comparisons, together with Ortelius’ claim in 1596 from a partly curved global Mercator projection that, ‘it was as if the Americas were torn apart from Africa/Europe’, provided a sequence of shoreline co-ordinate gathering peaks that transferred to evolving mapping methods and proved continental drift.
