One of the earliest historical reports of a far northern, snow-covered place was by Pytheas who sailed out of what is now Marseilles in 325 B.C., and discovered a place he called Ultima Thule, a six day journey north of Britain. No one knows exactly where his ship landed but people believe that it may have been Iceland, Greenland, Norway or the Shetlands. Pytheas described the remarkable midnight sun and reported that the sea surrounding Thule was "neither sea nor air but a mixture like a sea-lung that binds everything together."
In the following centuries the Romans and medieval scholars called the Far North "the kingdom of the dead" where the Cyclops lived "in a place of chaos, the abysmal chasm." In those days scholars also believed that the North Pole was a "gigantic metallic rock rising out of the ocean."
