Altuna stone U 1161 (RAÄ-nr Altuna 42:1) at Altuna church, Altuna parish, Simtuna district, Fjädrundaland, Enköping municipality, Uppsala county, Uppland, Sweden. Here you can see the lower part of the left side of the runestone where Tor's fish prison is shown. We see the god Thor with raised hammer in a boat with an ox's head on a reef and the Serpent of Midgard slashing at bait. Note that Tor stepped through the bottom of the boat.
