Viking Age to post-Viking Age

In the 11th century, chronicler Adam of Bremen recorded in a scholion of his Gesta Hammaburgensis Ecclesiae Pontificum that a statue of Thor, whom Adam describes as "mightiest", sat enthroned in the Temple at Uppsala (located in Gamla Uppsala, Sweden) flanked by Wodan (Odin) and " Fricco ". Regarding Odin, Adam defines him as "frenzy" (Wodan, id est furor) and says that he "rules war and gives people strength against the enemy" and that the people of the temple depict him as wearing armour, "as our people depict Mars". According to Adam, the people of Uppsala had appointed priests (gothi) to each of the gods, who were to offer up sacrifices (blót), and in times of war sacrifices were made to images of Odin.

In the 12th century, centuries after Norway was "officially" Christianised, Odin was still being invoked by the population, as evidenced by a stick bearing a runic message found among the Bryggen inscriptions in Bergen, Norway. On the stick, both Thor and Odin are called upon for help; Thor is asked to "receive" the reader, and Odin to "own" them.
