330 BC
Pytheas of Massalia was a Greek merchant, geographer and explorer who explored Britain and the waters north of Scotland. He described an island six days sailing north of Britain called “Thule.” This may refer to Iceland, but could also have been the coast of Norway, or the Shetland or Faroe Islands. Pytheas was the first person to record a description of the midnight sun, the aurora, and Polar ice.
