I have read Linneus Laponian journey in swedish. The original text is in swedish with lots of latin expressions. The notes were meant for a diary and not for publishing. However I found no mentioning of Tablut. Now, the version(s) I looked upon were incomplete, but there was a description of another game where you throw sticks.
(do skréše) Dež čekáš, až bodeš v něčem na taho, možeš bóchnót na "vechetat" o řádko "oževet" na dóležitym léstko, potem našteloj toďto hodnoto třeba na 30 sekond, abe se tě stav tvéch špilu oževoval rechléc. (Servant) (okázat šecke vechetávke)
