Finding ways to equate Pliny's Hilleviones, Tacitus' Suiones and Jordanes' Suehans was a goal pursued with special vigor in the 17th century by the Rudbeckians of the Swedish Hyperborean School, who hoped to show that Sweden was not only the home of the original Goths, but also the "womb of mankind". In the center of this movement was Uppsala professor and poly-scientist Olaus Rudbeck (1630–1702), whose work is described by Flemming Lundgreen-Nielsen, professor, Department of Scandinavian Studies and Linguistics, University of Copenhagen as follows: "By means of fantastical etymologies and bold combinations of historical and scientific facts, Olaus Rudbeck showed that Sweden was the cradle of mankind and all early civilization, identifiable with Plato's lost continent of Atlantis. He considered the Swedish language to be the mother of all other tongues and saw Greek and Roman mythology as distorted versions of now-lost Swedish proto-myths." The efforts to construct a long, glorious history for Sweden became a political aim at the time of the Thirty Years War and culminated with the era of Swedish expansionism.
