Snorri SturlusonThe Old Norse/Icelandic spelling of the name is Snorri Sturluson. Snorre Sturlason is the modern Norwegian and Snorre Sturlasson the modern Swedish spelling. For the construction of the name (a patronymic), see Icelandic naming conventions. English no longer features this type of name, except as a foreign word. Anglicization of Scandinavian names is not standard and varies a great deal. Encyclopedias and dictionaries nearly all list Snorri under his Icelandic name. Books and articles may use Snorre Sturleson, Snorri Sturlusson, Snorre Sturlson, Snorri Sturlson, Snorri Sturlusson, in addition to his Norwegian and Swedish names. (1178 ? September 23, 1241) was an Icelandic historian, poet and politician. He was two-time elected lawspeaker at the Icelandic parliament, the Althing. He was the author of the Prose Edda or Younger Edda, which consists of Gylfaginning ("the fooling of Gylfi"), a narrative of Norse mythology, the Skáldskaparmál, a book of poetic language, and the Háttatal, a list of verse forms. He was also the author of the Heimskringla, a history of the Norwegian kings that begins with legendary material in Ynglinga saga and moves through to early medieval Scandinavian history. For stylistic and methodological reasons, Snorri is often taken to be the author of Egils saga.

As a historian and mythographer, Snorri is remarkable for proposing the theory (in the Prose Edda) that mythological gods begin as human war leaders and kings whose funeral sites develop cults (see euhemerism). As people call upon the dead war leader as they go to battle, or the dead king as they face tribal hardship, they begin to venerate the figure. Eventually, the king or warrior is remembered only as a god. He also proposed that as tribes defeat others, they explain their victory by proposing that their own gods were in battle with the gods of the others.
