the roman poet vergilius, in the middle of the first century bc, refers to the north as “ultima thule”, i.e. the furthermost north. the roman author plinius, who lived during the first century ad, claims that the world's furthermost place at thule or tyle is the place described by the greek pytheas from marseille, who travelled from the mediterranean to the north in 300 bc. in the 1950s, the german researcher w. koepp links the above mentioned citations to the area of tylö in halland, sweden.
