His skull is unusually hard, and Thor breaks a cup by throwing it at Hymir's head.
[6] The Prose Edda provides the additional detail that while Thor was attempting to pull Jörmungandr in, his feet went through the bottom of the boat.
Scholar John Lindow notes that this may be a unique situation in Norse mythology, for if Loki also has a jötunn father, Fárbauti, he is only "enumerated among the Æsir" as Snorri Sturluson puts it in Gylfaginning, and thus not really part of their group.
[8] A stone slab that may be a portion of a second cross at Gosforth also shows a fishing scene using an ox head for bait.
[9] The legend is also depicted on the Altuna Runestone, but its image does not show Hymir, possibly due to the narrow shape of that stone.
