In 1717, Swedish professor Olof Rudbeck proposed about 100 etymologies connecting Finnish and Hungarian, of which about 40 are still considered valid. Several early reports comparing Finnish or Hungarian with Mordvin, Mari or Khanty were additionally collected by Leibniz and edited by his assistant Johann Georg von Eckhart. In 1730, Philip Johan von Strahlenberg published his book ("The North and East Parts of Europe and Asia"), surveying the geography, peoples and languages
