ultima Thule
UL-tih-muh TOO-lee
The farthest north — the edge of the known world, the place beyond which maps give way to imagination. In classical geography, Thule was the northernmost land; ultima Thule was the point past which no one had been.
Etymology
Latin: ultima (farthest) + Thule (the northern land described by the Greek explorer Pytheas around 325 BC).
