"...the Druids knew the Earth was a sphere and ... they knew about its dimension. Does the length of the Gallic league give any clue that this hypothesis has some validity? The leuga gallica or Gallic league of 2,222.5 m is usually thought to be a Romanised league, as was argued by Jacques Dassie, a specialist in aerial archaeology. As the Gallic league is also exactly 1-1/2 times the Roman mile, which measured 1,481.5 m, one possibility is that in Roman times the Gauls adopted a new league which was easy to convert to the Roman mile. Why not after all?"
