Description: The first realistic description of auroras is found in the Norwegian chronicle the King's Mirror from about 1230 AD. The book is originally written as a textbook, probably for the young King Magnus Lagabøte by his father. The youngster is taught about all possible matters that he would need to know as a future ruler of Norway. In contrast to the prevailing belief in medieval Europe, the aurora in the King's Mirror was said to be a natural phenomenon and was named Nordurljos, or northern lights.
