According to 13th-century poet Snorri Sturluson, she launched the largest of all ships at Baldr's funeral after the Æsir gods were unable to budge the vessel.
[9] It is told in Snorri Sturluson's Gylfaginning that at Baldr's funeral his wife Nanna died of grief and was placed alongside him on his pyre, thus joining her husband in Hel.
Þá gekk Hyrrokkin á framstafn nökkvans ok hratt fram í fyrsta viðbragði, svá at eldr hraut ór hlunnunum ok lönd öll skulfu.
As soon as she alighted, Odin ordered four Berserkir to hold her steed fast, who were, however, obliged to throw the animal on the ground ere they could effect their purpose.
She is also mentioned in a list of troll women by an anonymous skald:[12] Gjölp, Hyrrokkin, Hengikepta, Gneip ok Gnepja, Geysa, Hála, Hörn ok Hrúga, Harðgreip, Forað, Hryðja, Hveðra ok Hölgabrúðr.
The late 10th-century skald Þorbjörn dísarskáld, in two preserved fragments of the Skáldskaparmál (4) addressed directly to Thor, mentions Hyrrokkin among the jötnar killed by the thunder-god at Baldur's funeral:[3] Ball í Keilu kolli, Kjallandi brauzt þú alla, áðr draptu Lút ok Leiða, léztu dreyra Búseyru; heftir þú Hengjankjöftu, Hyrrokkin dó fyrri; þó var snemr in sáma Svívör numin lífi.
Andy Orchard's translation (1997)[14] The poem Húsdrápa ('House-Lay'), composed by Úlfr Uggason around 985 AD in western Iceland and partially preserved in the Prose Edda, also appears to refer to Hyrrokkin at Baldr's funeral: "The very powerful Hild of the mountains [giantess][a] caused the sea-Sleipnir [ship] to lumber forward, but the wielders of the helmet flames [warriors] of Hropt [Odin] felled her mount.
