The Norse god who was most popular was Thor, and the Altuna Runestone in Uppland shows Thor's fishing expedition when he tried to capture the Midgard Serpent. Two centuries later, the Icelander Snorri Sturluson would write: "The Midgarth Serpent bit at the ox-head and the hook caught in the roof of its mouth. When it felt that, it started so violently that both Thor's fists went smack against the gunwale. Then Thor got angry, assumed all his godly strength, and dug his heels so sturdily that his feet went right through the bottom of the boat and he braced them on the sea bed." (Jansson's translation). The Altuna Runestone has also included the foot that went through the planks.
